01 / precision
Tools that understand a codebase
List files, match paths, search with regex, and read line-by-line before making a targeted change.

Terminal coding harness
Let AI move fast.
Keep your hands on the wheel.
Beast gives language models a controlled, tool-driven interface for understanding a project, making targeted changes, and running approved commands.

Project-scoped sessions
Confirmation-gated commands
Streaming responses
The useful middle ground
More than chat.
Less than autopilot.
Beast puts the project and the model in the same loop, without handing over the keys. Every action is visible, scoped, and shaped for software work.
02 / control
Approval where it matters
Shell commands pause for confirmation. You stay in control of what runs on your machine.
03 / continuity
Long-running context
Resume project-scoped sessions, track live token usage, and compact context when work gets deep.
04 / compatibility
Bring the model you already use
Connect to OpenAI, OpenRouter, Groq, Mistral, Ollama, Google-compatible endpoints, or your own base URL.

A better operating rhythm
One harness.
Two intentional modes.
01Plan
Explore without risk
Give the model read-only access to inspect the codebase and produce an implementation plan without modifying anything.
> map the project
02Build
Make the change
Switch modes when the plan is clear. Beast exposes editing and execution tools, one deliberate action at a time.
> implement the plan
03Verify
Review what happened
Inspect the edits, approve commands as they appear, and keep the conversation available for the next iteration.
> run the tests
TAB Toggle between Plan and Build at any time.
