Hi @julienvallini, @fredisterik, and the rest of the Alpic team,

Wanted to send a quick note that has been overdue.

We've been leaning on @Skybridge heavily at Waniwani. It's now running across 50+ MCPs we've shipped to our enterprise customers, and it's core to every single one we build. What used to take us weeks to get an MCP shipped now takes a couple of hours to be fully production ready. That shift has been massive for us.

Beyond the framework itself, what's stood out is the team. You're always there, quick to respond, and clearly listening. Every piece of feedback we've raised has either been picked up or turned into a real improvement, and watching the framework get better release over release has been genuinely fun to be part of.

We're really happy to be partnering with you and excited to keep building alongside you as MCP apps grow. Keep doing what you're doing.

Best,

Maxime

Hey, Nikolay here, one of Alpic, the team behind Skybridge. Thank you for all the comments and feedback, it helps us making the product better everyday!

A very interesting framework! I always have plenty of ideas for improving construction site management, but lack the tools to bring them to life... I can't wait to try it out!

Juste tried this awesome framework in insurance product distribution ! This service will accelerate our business for sure.

I am one of the founder of Alpic. We built some of first apps in ChatGPT and we realized how big was the gap between modern development and MCP app development. We spent a lot of time these past few month to build the best react framework for MCP apps. Looking forward to see your feedback and contributions.

We believe dynamic UI generated by agent is the future and this is the first real successful iteration.

Amazing idea and framework. Let's try to build a logisitic app for my day to day job

I've been using Skybridge for now 3 months and I'd have to say that's the easiest way to build an MCP Apps. It has the whole loop to build, test (visually and also with a real LLM on the playground).

Kudos to the team !!

Awesome framework! I already player around a bit with Claude connectors but never had the chance to see ChatGPT app. I’ll give it a try! I’m working in architecture and so much still needs to be done in the space

The testing tunnel plus the client-compatibility layer is what catches my eye — the MCP-app dev loop across ChatGPT vs Claude clients seems like where most breakage would hide. With 'code once, ship everywhere,' how much per-client branching actually leaks into app code versus being abstracted by the framework? And for view rendering, does state stay scoped to the MCP server session, or is there shared client-side state I have to reason about across hosts?

Love that you tackled the cross host quirks head on, the code once ship everywhere abstraction with graceful polyfills is the unglamorous plumbing that actually makes building MCP apps feel sane.

Congrats guys - this looks super useful and I have passed to my Dev team. We have a few MCP's including a full telecoms stack so I am looking forward to us publishing them here.

Love the abstraction layer here. Building standard UIs while the big players fight over becoming an OS is a smart play. I haven't tested it yet, but it's next on my list. I'll give it a spin soon and will definitely ship some apps once Gemini finally joins the party and opens up an app store! 🚀

The interesting bit for me is the compatibility layer across assistants; MCP apps will be much easier to adopt if teams don’t have to maintain separate UI paths for Claude, ChatGPT, and internal agents.

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!
