[Other] Show HN: Free developer-first OneNote alternative Hey Everyone, been working on a note-taking app called janta (Just Another Note Taking App) the past few months.<p>You can try it out at app.janta.dev (you will be redirected to app.janta.dev&#x2F;canvas&#x2F;temporary, which is the locally-stored whiteboard you can access)<p>I felt limited with OneNote, Excalidraw, and other infinite-canvas style apps, so I built an alternative. You have access to code-editors, Desmos graphs, and rich text editors (SlateJS). This is because the canvas is designed in a way that allows web components to exist on the same layer as pen-strokes, so you can annotate code, circle points-of-inflection, and programmatically generate graphs using matplotlib.pyplot!<p>This is a beta release, and feedback would be awesome!

[Other] Show HN: Built an MCP server using Cloudflare's Code Mode pattern Read this article by Cloudflare this morning <a href="https:&#x2F;&#x2F;blog.cloudflare.com&#x2F;code-mode&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blog.cloudflare.com&#x2F;code-mode&#x2F;</a> the main argument being that LLMs are much better at writing typescript code than tool calls because they&#x27;ve seen typescript code many more times.<p>HN Discussion: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45399204">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45399204</a> <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45386248">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45386248</a><p>Deno provides a great sandbox environment for Typescript code execution because of its permissions system which made it easy to spin up code that only has access to fetch and network calls.<p>Stick an MCP proxy on top of that and you&#x27;ve got &quot;CodeMode&quot; (code intermixed with MCP tool calls) for more advanced workflow orchestration.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;jx-codes&#x2F;codemode-mcp" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jx-codes&#x2F;codemode-mcp</a><p>There&#x27;s a lot of things that can be improved here. Like a virtual file system for the agent to actually build up its solution instead of being forced to one shot the solution but the bones are there.

[Other] Show HN: Toolbrew – Free little tools without signups or ads I got tired of fighting through spammy tool sites just to do something simple, so I made Toolbrew in a few hours on Replit.

No signups, no ads.<p>If there is a tool you wish existed, you can request it on the site and I will build it. Do your worst. Seriously, ANY tool.<p>Maybe it helps, maybe not. Enjoy!
