Built for how devs actually work

Not another AI wrapper. A developer tool that fits your terminal and your workflow.

Predictable by default

All destructive operations support --dry-run. Mutations require confirmation unless --yes is passed.

Terminal-native

Built for CLI usage first. Scriptable, automation-friendly, CI-friendly. JSON output when you need it.

Repo-aware

Understands Next.js app router, Nest.js modules, Prisma schemas, tsconfig, and monorepo patterns.

Scope-honest

Focused on TS/Node and Python workflows. No fake 'works for everything' story.

Explicit bootstrap

No hidden runtime installation. No invisible setup. You see everything that happens.

Multi-provider

Anthropic, OpenAI, Ollama, OpenRouter. Choose your model, run locally or in the cloud.

Two focused tools

Intentionally split instead of one mixed runtime. Easier to explain, install, and trust.
