What is it?

DeepCode is an open agentic coding framework that lets an AI agent explore a codebase, edit files, run commands and tests, review changes, and carry a task through to a verified result. Its design centers on a goal-driven loop: the agent keeps working through understanding, implementation, verification, and repair rather than stopping after a single answer, and the user can add requirements, switch models, stop, or resume without discarding completed work.

The terminal UI, desktop app, and web workbench all connect to one shared local background service, so projects, session history, models, skills, permissions, and automations are consistent across interfaces. Sessions persist to disk, and tool activity, plans, code changes, and test results stay visible for review. Users can bring their own model providers, including local model servers, and extend the agent with reusable skills and MCP servers.

The project also includes Paper2Code, a workflow for turning research papers into runnable code, and supports headless execution for scripted or scheduled runs.

Key features

  • 01Terminal, desktop, and web clients share one local background service.
  • 02Goal-driven loop that continues through understanding, implementation, verification, and repair.
  • 03Sessions persist to disk and can be resumed, with tool activity and test results visible.
  • 04Supports user-configured model providers and per-session reasoning settings.
  • 05Extensible through reusable skills, MCP servers, and plugins.
  • 06Headless execution and recurring automations for repository maintenance tasks.

Use cases

  • Delegating bug fixes, test repair, or refactoring tasks to an agent working inside a local repository.
  • Turning a research paper into a runnable code implementation with Paper2Code.
  • Scheduling recurring checks such as regression tests or documentation upkeep.
  • Experimenting with multi-agent coding workflows using your own model providers.
