1. Show HN: Parent Docker Image Transparency And Daily Pull Request Compliance

URL: https://github.com/marketplace/www-signal-fyi

Author: kcrane3576

Description: site: https://www.signal.fyi/ Github Marketplace App: https://github.com/marketplace/www-signal-fyi

Available on GitHub Marketplace, signal.fyi provides developers with essential parent Docker image information directly in the PR body, supporting transparency, compliance, and efficiency. Here’s how it works:

- SBOMs and Vulnerability Summaries in Every PR: signal.fyi generates a Software Bill of Materials (SBOM; CycloneDX) for each parent Docker image, including a vulnerability summary by severity. This visibility helps teams assess risks directly in the PR, integrating security and compliance into the review process seamlessly.

- Automated Parent Docker Image Version Configuration: signal.fyi configures the latest secure version of the parent Docker image in the FROM line, ensuring that every build starts with an up-to-date, compliant base. This approach reduces the risk of outdated dependencies and simplifies image management for developers.

- In-Workflow Transparency for Faster PR Reviews: By bringing SBOM data, vulnerability summaries, and configured image versions directly into the PR, signal.fyi reduces the need for time-consuming manual checks, helping developers make quick, informed, and compliant decisions.

For teams aiming to streamline compliance and efficiency in their PRs, signal.fyi offers a free trial to explore how real-time Docker transparency can enhance your workflow. Join us in building a smoother, more secure development process.

URL: https://www.rocketjobs.app/

Author: theprophecy

Description: I was tired of major job boards like LinkedIn/Indeed/Glass Door having spammy, promotions, and irrelevant job postings. Especially in ML where it was a pain to find MLE roles specializing in Computer Vision.

So I built Rocket Jobs. It looks at your resume and then uses semantic search to match you to relevant job postings based on your actual work experience. I spent a lot of time improving this “RAG” system by trying different embedding vendors and techniques to improve retrieval quality.

I intend to keep this 100% free. I’m able to run it for $0 rn. I’m also parsing 2M tokens a day all for free because I’m just using a 8B param llama for free rn from cerebras, groq, and together.ai. I plan to migrate to gemini later.

Also getting free postgres from aiven.io and free hosting from heroku student discount valid for 2 years

17. Show HN: Jelly – A simpler shared inbox for small teams

URL: https://letsjelly.com/

Author: mlettini

Description: Hello HN!

I wanted to share something we at Good Enough (https://goodenough.us) built over the past year:

Jelly! https://letsjelly.com

Jelly is a simpler shared inbox for small teams (like us) to answer team email. We had just been sharing a login to Fastmail previously, but as email started getting busier, that really started to stink as a solution — no one knew who was going to answer what, if someone else saw an email or not, etc etc. And a Google Group would prove to be worse, as replies too easily got lost to personal inboxes if someone accidentally didn’t “Reply All”. It wasn’t great!

We went looking for a tool to solve these problems, but everything we found was way too much software, and really quite expensive charging per seat. We didn’t need a complex ticketing system. We just needed email, as a team, in a simple and sane way.

So we built Jelly! And we’re not charging per seat, so you can bring your whole team for a very affordable price. (As a quick comparison for our team of six: Jelly’s lowest tier costs just $29/month while Zendesk’s costs upwards of $330/month.)

We would love to hear thoughts from anyone on a small team that needs to handle shared email. Also, if you know of other teams in that same position, we’d appreciate you letting them know about Jelly. Thank you!

22. Show HN: Open-source Kibana alternative for logs and traces in ClickHouse

URL: https://github.com/hyperdxio/hyperdx/tree/v2

Author: mikeshi42

Description: Hi HN, Mike and Warren here! We’re excited to share some (early) work towards our next major version of HyperDX. HyperDX makes it easy to visualize/search logs & traces on top of Clickhouse (so incident & bug investigations hopefully go by a little easier). For example, if a team is thinking of migrating to Clickhouse for their observability data warehouse [1][2][3] usually due to cost or data privacy reasons, they can easily throw HyperDX on top to do the UI layer for analysis and dashboarding in a dev-friendly way (aka not needing to type paragraphs of SQL to find some logs)

Over the past year we’ve seen a ton of excitement in companies adopting Clickhouse-based observability stacks - but one of the biggest challenges we’ve seen is that the UI layer on top of Clickhouse is either clunky to use for observability use cases (ex. BI tools), or too tied to a specific ingestion architecture to scale to every use case (we used to be in this category!). For companies that needed more flexibility in how their data is ingested and stored (usually due to running at a large scale), there’s really no good options for a developer experience (DX) focused observability layer on top of Clickhouse (Shopify spent 3 years building it in-house!)

Our current release works completely in the browser - and it does this by building on top of Clickhouse’s HTTP interface, which our React app can directly talk to. This means you can actually try HyperDX in your browser on your own Clickhouse with no installation! This was fortunately easy for us to accomplish due to being full stack Typescript, making it incredibly easy to shift between server and client code. On top of this we’ve been spending time baking in performance optimizations to ensure that HyperDX can continue to leverage Clickhouse efficiently at larger data volumes. We do a few tricks like only fetching columns that are needed for the current search, and re-querying to expand the entire row if needed to fully leverage Clickhouse’s columnar nature (40% faster, ymmv!) - or rewriting queries to use materialized columns to speed up Map column access when available (10x faster!).

On the DX side: we support querying using both Lucene (ex. fullText property:value) and SQL syntax. We’ve found the former to be our favorite for how concise it is. Similarly for charts, our chart builder has been upgraded to accept SQL expressions as well, so you can leverage the full power of SQL, while avoiding typing paragraphs of boilerplate SQL for time series data. We also make it easy to switch between UTC/local timestamps! Lastly, we’ve added high cardinality outlier analysis by charting the delta between outlier and inlier events (a la bubble up) - which we’ve found really helpful in narrowing down causes of regressions/anomalies in our traces.

We have a lot more planned for the full release - but wanted to get this out early to hear your feedback and opinions!

23. Show HN: QA.tech – End-to-End Testing in Natural Language

URL: https://qa.tech/

Author: daniel_mp

Description: Hi, I’m Daniel, CEO of QA.tech. We’ve spent the past 18 months developing a cool tool that allows you to run end-to-end tests on any web application using natural language. Check it out and let us know what you think!

I used to be a CTO at a B2C marketplace and was taken aback that all qa agencies we talked to wanted to create a custom suite of tests from scratch. Even though we were essentially a e-com with the same functionality as everyone else. Why weren’t there any best practices?

Some time later my co-founders and I had moved on and were looking for the next thing to do. AI agents became a thing, and we wanted to use them to take test cases, written by humans, and perform them with bots.

A test case can be very vague, and test the overall functionality, like this: Sign up for an account and send an invoice

Or include as many specific instructions as you choose, like After signup, verify that the email contains an image of the Chinese zodiac of the year you entered as your birth date

The tech is still very early, and a bit slow in some cases, but I am genuinely impressed by how much the agent manages to solve by itself.

Some cool things about the tool:

All tests are recorded and you get a step-by-step replay of what happened

It tracks all console logs and network logs for easier debugging

It creates “Issues” of bugs found during test execution that you can export to Linear

It suggests test cases for you based on what we scrape from your URL

We have an open signup where you can try it out and create your own test cases.

https://app.qa.tech/auth/sign-up?code=site-signup

Hope this brings you some joy, and that you have some feedback for me.

Cheers

26. Show HN: RowMaker – Turn Images and Words into Spreadsheets

URL: https://www.simpltech.ai/?

Author: kenstler

Description: Hey All,

RowMaker is a simple utility app I built that helps you automate data entry into personal spreadsheets. RowMaker uses AI to turn pictures and voice notes from your phone into rows of data for personal use cases.

I built RowMaker for myself because I have a ton of use cases where I’d like to track information in a spreadsheet, but I’m way too lazy to do manual data entry. It occurred to me that, if the things I’m trying to track can be captured in an image or describe in a voice note, I can just use a multi-modal LLM to convert that raw data into a structured format that can be added to a spreadsheet. Hence, RowMaker.

Here’s how it works:

  1. Users create a “rowmaker”, which is a set of fields and descriptions that define the columns of a spreadsheet.
  2. RowMaker creates the spreadsheet in your Google Sheets account.
  3. Users can then take pictures or voice notes on their phone, and submit them to a rowmaker.
  4. RowMaker uses an LLM + the spreadsheet context to extract the necessary data from the picture/voice note.
  5. The extracted data is added as a new row to the spreadsheet.

    As an example, I used RowMaker to create a pantry inventory by defining the fields I wanted to track (food name, category, brand) and taking pictures of everything in my pantry.

    I’m releasing the app today on the app/play stores. The app has usage-based pricing based on credits - 1 extraction consumes 1 credit. New users get 20 credits free, and can purchase additional credits in increments of 100 for $1 / 100 credits.

    Today, RowMaker only supports Google Sheets for storing data, so you will need a Google account.

    This app is not meant to be a money-maker. My goal is to eventually use a local, on-device LLM for data extraction, so I can drop the LLM API calls and the usage-based pricing.

    Would love to hear your feedback!

34. Show HN: GazeFilter – A Web-Based Eye-Tracking Solution

URL: https://gazefilter.app

Author: rostyq

Description: Hello HN,

I’ve built a web-based eye-tracking solution that can be embedded into any website or even used with OBS Studio. It handles webcam access, calibration, different detection models, gaze tracking, and works entirely on the client side. All you need is a relatively up-to-date popular web browser, a connected web camera, and a well-lit environment around you.

A long time ago, I was looking for an eye-tracking solution for web browsers. I tried using WebGazer, but it didn’t meet my requirements. The performance was lacking because it relies entirely on JavaScript for computations. Additionally, its appearance-based calibration, which uses low-scale eye image patches, struggled with extrapolation, making it poor at predicting out-of-screen gazes.

To overcome these challenges, I started developing a JavaScript library, gazefilter.js, focusing on model-based gaze calibration and using WebAssembly for heavy computation. However, integrating such a library can be complex. It requires handling device selection, creating a calibration procedure, managing errors, and more. Since web browsers allow cross-origin messaging, I realized that a more user-friendly (and developer-friendly) approach would be to offer this as a web application. Gazefilter can be opened via an HTML iframe inside another website, handling all eye-tracking-related tasks. It allows end-users to select devices, choose detection models, read tips, and calibrate the gaze point.

You can try it out at gazefilter.app. Since I don’t use any client-side analytics and the documentation is still a work in progress, I’d really appreciate any feedback. Whether you’re integrating it into a website, setting it up with OBS Studio, or just trying out the demo to see real-time eye-tracking in action. You are welcome to open issues on GitHub or share your experience here.

38. Show HN: Danswer APIs – Open-source APIs for building RAG apps over company docs

URL: https://github.com/danswer-ai/danswer

Author: yuhongsun

Description: Hi HN! I’m one of the creators of Danswer, the open-source enterprise search project that you may have seen on HN a bit under a year ago (https://news.ycombinator.com/item?id=39467413). Really excited to be back to post about our new APIs :)

Over the last half-year the #1 thing we’ve heard from our open-source community is the desire to build custom applications on top of the core connections with common apps + search + assistants. While this has always technically been possible, it hasn’t been easy for two main reasons: (1) inability to use APIs with auth-enabled w/o grabbing cookies from the browser and (2) a lack of simple APIs. Well no longer!

For (1), we now provide a UI to generate API keys and for (2) we provide a pure “search” endpoint, a “chat” endpoint, and an implementation of OpenAI’s Assistants API. With these, we take care of all the boring stuff (integrating with 35+ tools, constantly keeping docs up-to-date, and handling permissions) and provide an opinionated starting point for the generic hard stuff (really good hybrid-search + factoring in metadata, recency, etc.), so that you can focus on the specific business logic of the app.

Back when I was at Alation, on-call for our team could have been made so much easier by a small, custom app that auto-responded to every alert based on Confluence, Slack, and a few Drive folders. Danswer’s APIs would power the core of this, and all I’d be left with are app-specific things like routing alerts to the right team member based on the document ownership of the cited documents.

For an example of what it looks like to use the APIs, check out this script here: https://github.com/danswer-ai/danswer/blob/main/examples/ass…!

If you’re curious what’s happening under the hood, check out our docs: https://docs.danswer.dev/system_overview.

Thanks, excited to hear your thoughts!

39. Show HN: Eidon AI – Decentralized AI Network for Next-Generation On-Chain Models

URL: https://app.eidon.ai

Author: lawrenceyan

Description: Hey HN, we’re thrilled to launch Eidon AI today, a decentralized AI network that rewards you for contributing real-world data through Quests. Think of Quests as a decentralized bounty system, but instead of slaying monsters, you’re helping train the next generation of AI by capturing frontier data, all while owning the data you collect and earning a stake in the future of AI.

Check it out: https://app.eidon.ai

We built Eidon because we believe AI should be decentralized and uncensored to unlock the full potential of humanity. Today, big tech monopolizes both data and models, giving nothing back to the people who were used to create it while imposing a lobotomized, censored version of reality. We’re here to change that, putting the power in your hands. You decide what data to share, and you’re rewarded for your data contributions and the subsequent value generated by the models built from that data.

Here’s how it works: The network assigns ‘Quests’ for specific data like images, video, and audio covering multiple environments, actions, locations, cultures, and perspectives of reality. You use the Eidon App to complete these Quests by uploading the requested data. Our AI Agent system verifies the quality and ensures the data is free from spam, enabling labeling-free collection. You’re rewarded based on the value, novelty, and demand for your contributions.

But our focus goes beyond just data collection. The long-term goal is to create fully on-chain AI models using this real-world, multimodal data. These models will be uncensored, permissionless, private, and highly personalized grounded in the diverse reality around us.

We see Eidon as the go-to platform for decentralized AI data collection whether it’s for training humanoids or building more personalized AI assistants. And for us, it’s really about what kind of AI future we want to create, dystopia or utopia? The AI is the blockchain, the blockchain is the AI. Eidon wants to see a decentralized, permissionless future where AI empowers human potential instead of controlling it.

We’d love your feedback! What kind of quests would you like to see? How would you use this decentralized data? If you’re a company or individual interested in specific types of data, we’re open to discussing any requests and would be happy to set up a conversation with your team. Email us at [email protected]

41. Show HN: Image Pig – API for AI images (limited 80% discount)

URL: https://imagepig.com/

Author: dqdcz

Description: TL;DR: I created a service called Image Pig that provides an API for generating and manipulating images using AI. The discount is below.

Dear HN,

I was not really happy with obstacles a programmer needs to overcome in order to integrate AI into image-related projects. I mean specific knowledge about different AI models, software and hardware setup. Even for a moderately experienced software developer, it can easily take weeks or even months to master AI for image processing. I believe that you should not need PhD in computer vision or to break your piggy bank to be able to generate a few images in your project.

So I created Image Pig, a simple API for AI images. As an MVP, it currently offers three different AI models for generating images and several handy tools for AI image manipulation, namely content replacement, face swapping, background removal, upscaling and outpainting.

Instead of buying an expensive hardware and fiddling with AI models, you just install a package (supporting Python, Node.js, PHP and Rust – more will come soon) and add AI images to your project within minutes.

It is still work in progress and I would really appreciate your feedback.

As a special thank you to the HN community, I prepared an exclusive (HN users only) discount. Just use one of the following links after creating an account.

Use https://imagepig.com/account/checkout/basic80/ for the Basic plan: 1000 images/month, rate limiting 4 images/minute.

Or use https://imagepig.com/account/checkout/standard80/ for the Standard plan: 4000 images/month, rate limiting 10 images/minute.

The links are valid only for the first 20 uses, because with such a huge discount, I am actually losing money on every active user.

I am looking forward to your comments.

42. Show HN: Open-Source,The underlying infrastructure of our profitable API Market

URL: https://github.com/APIParkLab/APIPark

Author: FreyLoong

Description: Yes, we have an API marketplace similar to RapiAPI, which has been operating for over two years. Its revenue is substantial enough to support our entire team of over a dozen people, so we’ve been exploring other directions as well.

We’ve noticed that advancements in large AI models are significantly impacting a variety of new products, and we’re also considering the potential of combining AI with APIs to unlock more possibilities.

However, we still lack deeper insights into how to effectively integrate AI with data-driven APIs and the specific industries and scenarios where this combination would be most impactful.

Therefore, we plan to open-source the underlying API gateway of our API marketplace, building it in public. This would allow anyone to share APIs with AI integrations or package prompts with AI into APIs for community use.

We’re eager to hear if anyone has additional suggestions. Feel free to submit an issue for us!

43. Show HN: Assindo – AI Assistant That Handle Your Phone Calls

URL: https://www.assindo.com/

Author: assindo

Description: Hi HN,

I created Assindo, an AI-powered virtual assistant to automate phone calls for busy professionals and parents (MVP). Balancing work with personal responsibilities left me losing time to missed calls, hold times, and scheduling tasks. Hiring a human virtual assistant was costly, so I built Assindo to automate and manage these phone-based tasks, freeing up my focus while ensuring no important call or task slips through the cracks.

### How It Works

- Outgoing Calls: Assindo can schedule appointments, handle customer service calls, and make reservations, navigating IVR menus (press “1” to …), managing hold times, and leave voice mails.

- Incoming Calls: It pickup on your behalf, transcribes the discussion, summarizes key info, and sets up follow-up tasks – so no critical call is missed.

### Next Steps

I just applied to YC 2025 (fingers crossed!) and am looking for early adopters to try Assindo and share feedback, as well as suggestions on new features to improve the experience.

Try it out at https://web.assindo.com/ or visit https://www.assindo.com for more info. Thanks, and I’d love any feedback!

Android and iOS will be released in few days, you can join the waitlist: https://www.assindo.com/waitlist

47. Show HN: Open-Source AI Test Conductor with Playwright/Puppeteer

URL: https://github.com/andytyler/playwright-ai

Author: andyjtyler

Description: Hey HN,

This weekend our team created Playwright-AI. It’s a tool that hooks Anthropic’s computer use model into Playwright (on top of Puppeteer) to execute browser tests from natural language test cases.

ai(”Test users can create a new project.”)

Why tho? Testing Sucks! We wanted to see if we could just feed test cases in natural language to AI and it would test them exactly as a human would do. Writing E2E UI tests is super brittle, you change sign in button to say login and everything breaks…! If you’ve written UX E2E tests in a large org I’m sure you will know this pain well. We were inspired by zerostep.com

Fully Open-Source: MIT-licensed, free to use, and open for contributions.

This is just the initial version, and we’re eager to learn and make it even better, based on community feedback.

48. Show HN: BabelViz -Machine Translate Tableau Dashboards into over 150 Languages

URL: https://babelviz.com

Author: celue

Description: Hey HN!

I built BabelViz, a Tableau dashboard extension that translates dashboards automatically into over 150 languages.

The idea came from seeing global teams wrestle with static language solutions and relentless, frustrating tweaks. Tasks like duplicating workbooks, managing calculated fields, and regression testing (since Tableau updates could alter the underlying XML structure) made localization a serious challenge.

With BabelViz, translation is as simple as dragging and dropping the extension onto your dashboard. You get automatic translations, personalized language preferences that persist without users needing to change settings manually, and custom glossaries for translation overrides. This way, you retain translation control over specific terms to ensure accurate and consistent messaging for your audience. BabelViz also operates as a secure, on-premises solution for privacy and data security.

Would love to hear what you think, any feedback, or questions on this. https://babelviz.com

55. Show HN: I just launched my first SaaS - Timelogga

URL: https://www.timelogga.io/

Author: mazahermuraj

Description: Hey Guys

I’m a frontend developer and for nearly 7 years I’ve been building and shipping products for my employers. I’ve freelanced during that time too.

The problem with freelancing wasn’t finding a gig. Thankfully I found many and many found me. The problem was accurately tracking my time and quickly creating a timesheet ready to submit so I could be paid for my work.

I built Timelogga.io so I could solve that problem.

Now I generate timesheets quickly for the tasks that I’ve worked so I don’t need to worry about creating one manually. That was a very long task and honestly, it was the most boring and time-consuming part of freelance work - which sadly, was NOT a paid endeavour!

Sometimes, I was late for my payment submissions because the timesheet wasn’t ready.

I tried tools like Google Sheets and other similar products but they were either limited, too bloated for what I needed or just too expensive (especially when I was starting out!).

Now that I can easily track my tasks and create a timesheet quickly, I focus my time and energy on what matters and gets me paid. My work.

LATEST new feature: You can now pause ongoing tasks and start new ones.

I hope you enjoy it. I’d love some feedback, some sales and your support.

Thank you.
