Your AI agent gets worse as your project grows. VibeDrift catches the drift, fixes it, and gives your agent the context to stop making it.

About Overplane

Overplane is an AI code generation and build system that verifies and safely compiles plain-language specs into working, verified code. Container-sandboxed agents, replayable builds, and multi-agent support. Overplane combines popular AI coding agents with containers, spec-driven development, and formal verification to create a safer and more reliable AI coding workflow. Overplane keeps the speed and fixes the rest in three moves: contain the agent, wrap it in a real build system, and verify the plan before the code exists.

About VibeDrift

Your AI agent gets worse as your project grows. VibeDrift catches the drift, fixes it, and gives your agent the context to stop making it. See exactly how it works, free to use and fully public. Mid-task, Claude Code and Cursor ask your codebase what it already does, and get an evidence-backed answer in under a second. With and without VibeDrift, graded by an independent pass, it only changes things when the model would've gotten it wrong, and we show where it did nothing.
