[Other] Show HN: I build a cheap Skype Clone I build a skype clone, where you can make international calls via browser.<p>Skype was my go to app for that, but since they shut it down, decided to build my own. Its perfect for calling international customer support, or any other gov numbers.<p>Its pay-as-you-go - so no subscription charges, very transparent pricing. You can just top up $5 and see pricing in real time during the call.

[Other] AI-Automated-Trading-Framework Combine a large language model API and an exchange API. The system periodically retrieves exchange data, sends it to the AI, and uses tailored prompts so the AI outputs commands in a format recognized by the exchange API—enabling fully automated trading. - a985783/AI-Automated-Trading-Framework

[Other] ai-sdk-panel: the config panel for ai sdk. The LLM Providers editor for ai sdk providers. Many AI applications require editing and managing Providers, and doing this well takes considerable effort. Having built several AI applications, I found myself constantly reinventing the wheel, developing a separate LLM provider editor for each one. The project includes complete end-to-end (e2e) testing, built and tested using the latest Vitest 4.0 Browser Mode.

[Other] Show HN: IRCd in Pure Bash In <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45755788">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45755788</a> there was mention of an IRC server using gawk, but no code. So I wrote an IRCd in pure bash.

[Other] Show HN: Ellipticc Drive – open-source cloud drive with E2E and PQ encryption Hey HN, I’m Ilias, 19, from Paris.<p>I built Ellipticc Drive, an open-source cloud drive with true end-to-end encryption and post-quantum security, designed to be Dropbox-like in UX but with zero access to your data, even by the host.<p>What’s unique:<p>Free 10GB for every user, forever.<p>Open-source frontend (audit or self-host if you want)<p>Tech stack:<p>Frontend: Next.js<p>Crypto: WebCrypto (hashing) + Noble (core primitives)<p>Encryption: XChaCha20-Poly1305 (file chunks)<p>Key wrapping: Kyber (ML-KEM768)<p>Signing: Ed25519 + Dilithium2 (ML-DSA65)<p>Key derivation: Argon2id → Master Key → encrypts all keypairs &amp; CEKs<p>Try it live: <a href="https:&#x2F;&#x2F;ellipticc.com" rel="nofollow">https:&#x2F;&#x2F;ellipticc.com</a><p>Frontend source: <a href="https:&#x2F;&#x2F;github.com&#x2F;ellipticc&#x2F;drive-frontend" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ellipticc&#x2F;drive-frontend</a><p>Would love feedback from devs and security folks — particularly on encryption flow, architecture, or UX.<p>I’ll be around to answer every technical question in the comments!

[Other] Launch HN: Propolis (YC X25) – Browser agents that QA your web app autonomously Hi HN, we&#x27;re Marc and Matt, and we&#x27;re building Propolis (app.propolis.tech&#x2F;#&#x2F;launch). We use browser agents to simulate users in order to report bugs and write e2e tests. Today, you can launch 10s-100s of agents that collaboratively explore a website and report back on pain points + propose e2e tests that can run as part of your CI.<p>You can try an initial run (two minute set up) to get a feel for the product for free here: app.propolis.tech&#x2F;#&#x2F;launch. Or watch our demo video: <a href="https:&#x2F;&#x2F;www.tella.tv&#x2F;video&#x2F;autonomous-qa-system-walkthrough-3s4e">https:&#x2F;&#x2F;www.tella.tv&#x2F;video&#x2F;autonomous-qa-system-walkthrough-...</a><p>The Problem<p>Both Matt and I have been thinking about software quality for the last 10 years. While at Airtable Matt worked on the infrastructure team responsible for deploys and thought a lot about how to catch bugs before users did. Deterministic tests are incredibly effective at ensuring pre-defined behavior continues to function, but it&#x27;s hard to get meaningful coverage &amp; easy to &quot;stub&#x2F;mock&quot; so much that it&#x27;s no longer representative of real usage.<p>I like to pitch what we&#x27;re building now as a set of “users” you can treat like a canary group without worrying about impacting real users.<p>What we do: Propolis runs &quot;swarms&quot; of browser agents that collaborate to come up with user journeys, flag points of friction, and propose e2e tests that can then be run more cheaply on any trigger you&#x27;d like. We have customers from public companies to startups running &quot;swarms&quot; regularly to massively increase the breadth of their automated testing + running the produced tests as part of their CI pipeline to ensure that more specific flows stay working without needing to worry about updating playwright&#x2F;selenium tests.<p>One thing that really excites me about this approach is how flexible &quot;checks&quot; can be since they&#x27;re evaluated partially via LLM, for example we&#x27;ve caught bugs related to the quality of non-deterministic output (think a shopping assistant recommending a product that the user then searches for and can’t find).<p>Pricing and Availability<p>It&#x27;s production-ready today at $1000&#x2F;month unlimited-use + active support for early users willing to give feedback and request features. We&#x27;re also happy to work with you for capped-use &#x2F; hobby plans at lower prices if you&#x27;d like to use it for smaller or personal projects.<p>We&#x27;d love to hear from the HN community - especially curious if folks have thoughts on what else autonomous agents could validate beyond bugs and functional correctness. Try it out and let us know what you think!

[Other] Show HN: I made a heatmap diff viewer for code reviews 0github.com is a pull request viewer that color-codes every diff line&#x2F;token by how much human attention it probably needs. Unlike PR-review bots, we try to flag not just by &quot;is it a bug?&quot; but by &quot;is it worth a second look?&quot; (examples: hard-coded secret, weird crypto mode, gnarly logic, ugly code).<p>To try it, replace github.com with 0github.com in any pull-request URL. Under the hood, we split the PR into individual files, and for each file, we ask an LLM to annotate each line with a data structure that we parse into a colored heatmap.<p>Examples:<p><a href="https:&#x2F;&#x2F;0github.com&#x2F;manaflow-ai&#x2F;cmux&#x2F;pull&#x2F;666" rel="nofollow">https:&#x2F;&#x2F;0github.com&#x2F;manaflow-ai&#x2F;cmux&#x2F;pull&#x2F;666</a><p><a href="https:&#x2F;&#x2F;0github.com&#x2F;stack-auth&#x2F;stack-auth&#x2F;pull&#x2F;988" rel="nofollow">https:&#x2F;&#x2F;0github.com&#x2F;stack-auth&#x2F;stack-auth&#x2F;pull&#x2F;988</a><p><a href="https:&#x2F;&#x2F;0github.com&#x2F;tinygrad&#x2F;tinygrad&#x2F;pull&#x2F;12995" rel="nofollow">https:&#x2F;&#x2F;0github.com&#x2F;tinygrad&#x2F;tinygrad&#x2F;pull&#x2F;12995</a><p><a href="https:&#x2F;&#x2F;0github.com&#x2F;simonw&#x2F;datasette&#x2F;pull&#x2F;2548" rel="nofollow">https:&#x2F;&#x2F;0github.com&#x2F;simonw&#x2F;datasette&#x2F;pull&#x2F;2548</a><p>Notice how all the example links have a 0 prepended before github.com. This navigates you to our custom diff viewer where we handle the same URL path parameters as github.com. Darker yellows indicate that an area might require more investigation. Hover on the highlights to see the LLM&#x27;s explanation. There&#x27;s also a slider on the top left to adjust the &quot;should review&quot; threshold.<p>Repo (MIT license): <a href="https:&#x2F;&#x2F;github.com&#x2F;manaflow-ai&#x2F;cmux" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;manaflow-ai&#x2F;cmux</a>
