You deserve better
Building software shouldn't feel like gambling. Popular AI coding tools work like slot machines—credits run out mid-project, token limits force impossible choices, and when something breaks, debugging is pure luck. We built Replay Builder because you deserve better.
Today we're launching Replay Builder: unlimited app building with no token limits, flat pricing, and production-ready apps you can start with. Build as much as you want, for as long as you want, for one price.
From Nut.new to Replay Builder
If you've been using Nut.new, you already know what Builder can do. Today we're giving it a name that matches our ambition, and pays homage to the debugging engine we’ve already built that we baked into it. We’ve created reference apps to get you started faster, flat pricing so you never worry about running out of credits, and a clear message: own your tools, own your data.
Why We Built This
Our team spent years building Replay DevTools, a deterministic debugger trusted by engineering teams at Vercel, Glide, and Pantheon. We learned that the hardest problem in software isn't writing code—it's understanding what broke and why. That insight became Replay Builder's secret weapon: every app you build has deterministic debugging built in. When something breaks, Builder can replay exactly what happened and fix it fast.
Who Builder Is For
Consultants building software for clients: Create custom tools your clients will own. No vendor lock-in to explain, no per-seat pricing to justify, no limits on what you can build. Your clients own their apps and their data, completely.
Small teams replacing expensive SaaS: We know you’re tired of paying for bloated SaaS tools with features you’ll never even use. We’re tired of it too! Build CRMs, issue trackers, time tracking tools, and knowledge bases specialized to your business—and own them forever.
Start with Production-Ready Reference Apps
We're launching with a small but growing library of complete web applications that the Replay team actually uses every day:
Telemetry Board – Listens to OpenTelemetry events and lets you build custom dashboards and visualizations for telemetry data.
Issue Tracker – Bug tracking and feature management for your team. Built by developers who got tired of paying for Jira.
Time Tracking & Invoicing – Track hours, generate invoices, and manage client billing. Perfect for consultants and small agencies.
Team Wiki – Internal documentation and team knowledge management that your team will actually use.
Customer Feedback Portal – Let your customers tell you what they want you to improve, and let the community vote on the best ideas.
These aren't templates or prototypes. They're real, working applications. Copy them for free, customize everything, and make them yours. We use these apps to run Replay—now you can use them to run your business.
Build Anything, Own Everything
With Replay Builder, you can create web apps that:
- Have a full database backend via our deep integration with Supabase
- Connect to ChatGPT and Claude for sophisticated AI-powered features without needing your own third-party API keys
- Send SMS messages to communicate with customers and send transactional updates
- Pull information from documents and spreadsheets, and write data back to them
- Send notifications and transactional emails for new signups and user actions
- Handle photo, video, and file uploads with built-in image resizing and compression
- Integrate with any third-party service that can trigger webhook events
No token limits. No usage caps. No surprises.
Free plan: Build one app to get started, or copy as many reference apps as you want
Builder plan: Build as many apps as you want, use them as much as you want
If Builder struggles to accomplish what you need, the Replay team will be there to support you. We're continuously improving Builder—adding new reference apps and major features based on what you tell us you need.
The Difference That Matters
Every other no-code tool in the market makes you play the slot machine. Will you have enough credits to finish your project? Will you hit your token limit right when you need to ship? Will debugging eat your entire budget?
We don't want you to stress about token balances. We want you to build and nurture your apps for the long term. That's why we shifted to flat subscription pricing—to differentiate ourselves from every other player whose customers complain about feeling nickel-and-dimed.
And when something does break (because something always breaks), you have deterministic debugging built in. The built-in Replay debugging engine can see what happened, understand the root cause, and fix it—without burning through debug credits or filing support tickets.
