Compyle

Compyle is a coding agent designed for software engineers who want to maintain control over their projects. Unlike fully autonomous agents, it takes a question-driven approach: understanding your task thoroughly, generating research and planning documents, and validating changes against your decisions before implementation. It stops and asks if something doesn't align with your plan.

The platform uses multiple oversight agents to catch bad patterns, ensure consistency with your project rules, and keep you informed throughout development. Built on Claude's Agent SDK with Sonnet 4.5, it runs in sandboxed environments to safely execute code. The makers say they built Compyle by orchestrating Claude Code instances, drawing on their experience where rapid prototyping led to codebases they no longer fully understood.
