[Other] Remembering Planet Source Code: Sharing Code Before GitHub Made It Easy

[Other] The ultimate space for work and life — to find, build, and collaborate with agent teammates that grow with you. We are taking agent harness to the next level — enabling multi-agent collaboration, effortless agent team design, and introducing agents as the unit of work interaction.

[API/SDK] Show HN: GETadb.com – every GET request creates a DB Hey HN! We made GETadb.com, so it&#x27;s easier to get agents to build you full stack apps. You don&#x27;t need to give them any credentials. Just by loading a GET request, they get access to a database, a sync engine, and abstractions for auth, presence, and streams.<p>To see what the agent sees, you can load https:&#x2F;&#x2F;getadb.com&#x2F;new<p>There&#x27;s two fun things about how it&#x27;s implemented:<p>1. If you curl the home page, it the agent content rather than human content. We do this by detecting the &#x27;Sec-Fetch-Mode&#x27; header. It&#x27;s not perfect, but gets the job done for Claude Code et al.<p>2. For an agent to spin up an app, they make _two_ fethes. (1) getadb.com&#x2F;guide tells them to generate a uuid, and fetch (2) getadb.com&#x2F;provision&#x2F;&lt;uuid&gt;. We did this, because just about half of the popular web-based app builders cache URLs globally, even if you return no-store headers. To get around this we just instruct the agent to generate unique URLs<p>You may wonder: Why GET requests, rather than POST requests? It&#x27;s because then you can build in surprising places. For example, we get meta.ai to build an app inside the artifact preview: https:&#x2F;&#x2F;artifacts.meta.ai&#x2F;share&#x2F;a&#x2F;b80c7412-c3af-4088-b430-78efdfe8ea2d<p>Under the hood, this is possible because the whole infra is mult-tenant from ground up. We already announced how that works on HN, but if you&#x27;re curious here&#x27;s the essay for it: https:&#x2F;&#x2F;www.instantdb.com&#x2F;essays&#x2F;architecture

[Other] Show HN: Notion-to-site – sync any Notion database to local Markdown/MDX/JSON Built this while syncing my own blog from Notion. Good alternative to paid options like Super.so.<p>Supports incremental sync, all Notion block types including equations and synced blocks, image download + WebP conversion, and adapters for Markdown, MDX, and JSON.<p>Works with Next.js, Astro, SvelteKit, and anything that reads files.

[Other] Show HN: Git for AI Agents hi guys. been working on something i think is fundamentally missing in today&#x27;s workflow with ai agents.<p>vcs.<p>i find myself struggling with questions that agents can&#x27;t answer like &quot;why did you do it?&quot;, &quot;when did u delete this folder? why?&quot;, etc. or trying to &#x2F;rewind (after a &#x2F;compact...) or basically `bisect` to find when and why something was done by the agent in the current &#x2F; previous session.<p>just like git did for code, i think we are the same core capabilities with ai agents<p>so...<p>i developed an open source solution for that (currently supporting claude code)<p>would love to get feedback, contribution or maybe other ideas or solutions you find for those problems.

[CLI Tool] Show HN: Crit – local review tool for agent plans and code diffs Crit is a single-binary CLI that opens your file or code diffs in a browser with GitHub-inspired interface. Your favourite agent acts on the feedback and responds back - continue until you&#x27;re happy.<p>I&#x27;ve been building this for a few months now and it&#x27;s been helping me a lot juggling parallel conversations with agents, making it easier to actually review the plans they generate and the resulting code - all before it hits GitHub.<p>It also allows you to export the plans to a hosted service (which you can self-host for privacy), to solicit feedback from your team. No account needed, and reviews are automatically deleted after 30 days of inactivity.

[Other] Show HN: DiffCAD, a FreeCAD workbench to review model changes like code I&#x27;d like to share a new workbench I&#x27;ve been working on called DiffCAD. Coming from a software engineering background, not having the ability to properly diff my CAD model changes was driving me crazy. This project scratches my own itch, and maybe someone elses&#x27;, too!<p>I&#x27;m open to feedback, ideas, and contributions. Cheers!

[Testing] Show HN: Resurf – realistic, reproducible test framework for AI browser agents Systematic testing of browser agents today is not easy: testing on real websites is flaky, rate-limited and potentially expensive (e.g. using proxies or bypassing Captcha), while static-HTML benchmarks lack state and dynamic behavior.<p>Resurf gives your browser agent a realistic, stateful, instrumented framework — built on synthetic websites with failure-mode injection:<p>- Realistic, dynamic, interactive environment - Deterministic &amp; reproducible - Failure-mode injection (latency, payment errors, 5xx) - Auditable success eval (DB state, not LLM judge) - No dependency on live websites - Browser Use and Stagehand supported out of the box
