MCP apps are the new website: they're real, interactive apps that run right inside AI assistants like ChatGPT and Claude. The tooling to build them didn't exist, so we built it. Meet Skybridge, the React framework that handles the infrastructure and the dev loop so you can focus on your features: MCP server, view rendering, client compatibility, testing tunnel, and more. Code once, ship everywhere. Already +500K downloads and dozens of apps in the stores!
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.
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 Skybridge. It is an open-sourceframework to build MCP apps, from idea to the official app stores. Code once, ship everywhere.
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.
Want proof the hard parts work? Have a look at our showcase page. 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.
What's happening in the MCP world right now is wild, and we can't wait to see what you build with it 💫
The "code once, ship everywhere" angle is the part that resonates — I build a lot of my own tooling on top of MCP and the host quirks between Claude and ChatGPT are exactly the kind of friction that quietly eats a weekend. The compliance-scanning piece caught my eye too; that's not where most early frameworks put their attention. Curious how you handle host capability divergence — when one host supports a UI primitive the other doesn't, do you degrade gracefully or gate the feature? Congrats on #1.
This resonates — I'm building voice/WhatsApp AI agents on top of Vapi + Twilio + Anthropic, and the "each host has its own quirks" pain is real even with just 3 providers, let alone every MCP client. The nastiest bugs aren't the obvious API mismatches, they're silent ones: I just spent hours chasing a bug where a local .env file baked into a Docker image was silently overriding production secrets at runtime — same code, different environment, completely different behavior, no error thrown. Curious how Skybridge handles that class of problem: env/config drift between the local emulator and the actual Claude/ChatGPT/VS Code runtimes. Is that abstracted away too, or still something devs have to test for per-host?
500K downloads before the PH launch says everything. What's the most unexpected thing someone built on top of it so far?
We use this framework as well at Noodle Seed. Love the dev tooling and all the conveniences it has! @Skybridge is amazing!
Very interesting the core concept here. The biggest bottleneck with bridge/integration tools is usually maintaining stable connections when the underlying third-party APIs update or throttle. Have you built a custom webhook fallback system to handle those latency drops, or are you relying on standard polling? Congrats again on the launch!
As someone who's been creating podcasts, newsletters, social posts, and now launching a product, I've found the biggest challenge isn't creating content; it's actually staying on brand across different formats. Interesting approach. Congrats on the launch.
MCP apps still feel like a wild west right now, I've been hacking on
one for a personal project and the dev loop is genuinely painful.
The testing tunnel piece especially.
How does the client compatibility layer work in practice? Different
hosts seem to render the same MCP differently and that's been driving
me mad.
The idea that MCP apps could become the "new websites" is really interesting. Curious what the biggest challenge has been in making apps work consistently across different AI assistants like ChatGPT and Claude?
Congratulations on the launch of Skybridge! How are you handling the identity building blocks involved in this? MCP auth spec, credential storage, etc.?
Love that it handles MCP server + view rendering out of the box. As someone building inside AI assistants, this removes so much friction. Any plans for more client compatibility (e.g. custom UIs)?
You mention it’s agent-ready. What does that concretely mean once I’m building with it?
Just tried and it's amazing ! Will be using it across our companies at Hexa !
Recently released our MCP server at CodSpeed. Didn’t know about Skybridge at the time but will definitely take a look. I used @modelcontextprotocol/server directly.
Why would I gain by switching to Skybridge, what would I lose?
And how difficult the transition would be?
Very nice, thanks for sharing! I didn’t see before the existence of an app store on ChatGPT. How long does it take for an app to be accepted upon submission ?
You guys made me open ProductHunt after a long time. Had a good time at one of your hackathons, and I was genuinely surprised how easy Skybridge made building MCP apps.
Looks like a cool initiative, I’ll give Skybridge a try!
I’m new in the space, is there any experience in particular that you feel this new surface to be adequate for? Any idea worth exploring first?
Congrats on the launch ! Question from the document-infra side: how does Skybridge handle rendering for heavier components like a document or PDF viewer vs lighter interactive UI?
