Skybridge

<p>👋 Hey Product Hunt!<br><br>The internet is going headless. More and more, people don't open a website or an app, they just ask an assistant. That's making MCP Apps the new UI: real, interactive apps that run right inside Claude, ChatGPT and the rest. We think it's one of the biggest shifts in how software gets built and used right now.<br><br>While building these apps at Alpic, we kept hitting the same wall: every host (Claude, ChatGPT, Cursor…) has its own quirks, and writing the plumbing to support all of them is painful. So we built <strong>Skybridge</strong>. It is an open-source<strong> </strong>framework to build MCP apps, from idea to the official app stores. Code once, ship everywhere.<br><br>It abstracts away the implementation differences, so your app runs the same in Claude, ChatGPT, VS Code and any MCP-compatible client. It bundles a full local emulator, Hot Module Reload and an instant tunnel to connect your local app to Claude and ChatGPT. Agents are first-class users too: Skybridge gives your coding agent everything it needs to build an MCP app end-to-end.<br><br>Want proof the hard parts work? Have a look at our <a href="https://www.skybridge.tech/showcase" target="_blank" rel="nofollow noopener noreferrer">showcase page</a>. You'll find many of the apps the community and us made with Skybridge and published to the stores. Skybridge already powers dozens of apps live in the stores.<br><br>What's happening in the MCP world right now is wild, and we can't wait to see what you build with it 💫</p>

<p>👋 Hey Product Hunt! I'm Fred, co-founder and CTO of Alpic, and core maintainer of Skybridge!<br></p><p>When ChatGPT Apps launched in October 2025, the OpenAI Apps SDK was just a page of documentation. No runtime, no tooling, nothing. So we built the missing SDK ourselves. That was Skybridge, day one.<br></p><p>But the deeper frustration was the feedback loop. Hot Module Reload, instant iteration, host context mocking (like locale, theme, or screen size), things web developers have taken for granted for a decade, mostly natively supported in modern browsers, simply didn't exist for AI Apps. Every change meant a full restart, a metadata refresh, and manually reconnecting to your conversational agent. The stack was brittle at best. When your feedback loop takes ages, you stop experimenting. You stop building.<br></p><p>So the DevTools became a core pillar of Skybridge: a local-only environment where you can iterate freely on your app before ever connecting it to Claude or ChatGPT. Tight loop, no friction.<br></p><p>Fully open-source. Because foundational tooling for this new layer of the web should be built in the open.</p><p>Since then, we've seen the number of apps built with Skybridge skyrocket! We've made the DevTools both human- and agent-friendly, enabling development loops we couldn't have even dreamed of 6 months ago. Can't wait to see what experiences people will bring to life with Skybridge.<br></p><p>If you want to give it a go yourself, check out our <a href="https://docs.skybridge.tech/quickstart/create-new-app" target="_blank" rel="nofollow noopener noreferrer">getting started guide</a>!</p>

<p>Huge👏 congrats <a href="https://www.producthunt.com/@julienvallini" data-node-type="mention" data-mention-type="user" data-mention-id="julienvallini" target="_blank" rel="nofollow noopener noreferrer">@julienvallini</a> on the release, the headless web framing is spot on. love it's a open source, qq. do we have to deploy to alpic cloud to get the store auditing features or can we run the full beacon compliance scan locally via the cli?</p>

<p>Thanks for the release! I have been using Skybridge to develop a few apps and v1 has made it a breeze, especially with the new devtools UI !</p><p></p><p>Shoutout to the team who made it happen ! </p>
