Help us build the perfect debugger for your coding agent.
We're partnering with a small group of engineering teams to go deep on how Replay MCP fits into real workflows. You get free access and a direct line to our team. We get honest signal on what to build.
Your agent is only as good as what it can see.
Coding agents are getting genuinely good at writing code. But when something breaks at runtime — a flaky test, a race condition, a bug that only happens in production — they're flying blind. No DOM state. No network timing. No component tree. Just your codebase and a guess.
Replay MCP closes that gap. It gives your agent the browser runtime context it needs to diagnose bugs precisely — and fix them the first time. We're looking for engineering teams who want to help us make that experience as useful as possible.
What design partners get
This isn't a beta waitlist. It's a working relationship.
Free for the full engagement
Full access to Replay MCP at no cost for the duration of the partnership — a minimum of 30 days, up to three months. No credit card. No catch. Use it on real work.
Direct line to the engineering team
You'll have access to the Replay engineering team in Discord. Ask questions, share feedback, or just tell us when something doesn't work the way you expected.
Your workflow shapes the product
We'll schedule occasional calls to hear how you're using Replay MCP — what's clicking, what's still painful. Your feedback directly influences what we build next.
Preferred pricing when you're ready
At the end of the engagement, we're happy to work out friendly pricing that reflects the relationship we've built. Design partners won't be treated like strangers at renewal.
Who this is for
Replay MCP is purpose-built for debugging React-based web apps. If your team has meaningful surface area in React — a product, a platform, an internal tool — and you're using AI coding agents like Cursor, Claude Code, Copilot, or Windsurf to build and fix it, this program is designed for you.
If your stack is primarily mobile, backend, or outside the React ecosystem, Replay MCP probably isn't the right fit yet. We'd rather be honest about that upfront than waste your time.
What matters beyond the stack: you care about making the debugging loop faster, and you're willing to tell us honestly when something doesn't work the way it should.
