Replay Builder is a newly launched software tool offering unlimited app building with flat pricing and no token limits, emphasizing ownership of tools and data. Transitioning from Nut.new, it integrates a deterministic debugger from Replay DevTools, enabling users to easily identify and fix issues. Aimed at consultants and small teams, it allows creating bespoke applications like CRMs and issue trackers without vendor lock-in. Replay Builder comes with production-ready reference apps such as a Telemetry Board and Issue Tracker, which can be copied, customized, and used freely. It supports integration with services like Supabase, ChatGPT, and Claude, and offers seamless data handling and communication features. By eliminating usage caps and focusing on long-term app management, Replay Builder sets itself apart from traditional no-code tools, ensuring users can build and maintain applications without the stress of token limitations or unexpected costs.
