About

AtomCode is an open source AI coding agent that lives in the terminal and autonomously reads files, edits code, runs commands, searches the web, executes tests, and self-verifies until a task is complete. It is designed as a multi-model alternative to tools such as Claude Code and Cursor Agent, supporting Claude, OpenAI, DeepSeek, GLM, Qwen, Ollama, SiliconFlow, and any OpenAI-compatible API. Its built-in code graph tools provide symbol indexing, reference lookup, caller and callee tracing, dependency analysis, and blast-radius analysis to help the agent understand large codebases more deeply than basic text search. Developers can attach screenshots and images, while vision preprocessing can extract useful context when the selected primary model does not support images directly. AtomCode integrates natively with AtomGit for OAuth login, repository management, issues, and pull requests, and supports MCP, reusable Skills, plugins, custom slash commands, hooks, and workflows.

About

OpenCode is the AI coding agent purpose-built for the terminal. It delivers a responsive, themeable terminal UI that feels native while streamlining your workflow. With LSP auto-loading, it ensures the right language servers are always available for accurate, context-aware coding support. Developers can spin up multiple AI agents in parallel sessions on the same project, maximizing productivity. Shareable links make it easy to reference, debug, or collaborate across sessions. Supporting Claude Pro and 75+ LLM providers via Models.dev, OpenCode gives you full freedom to choose your coding companion.

Pros & Cons from Real Users

Pros

  • OpenCode feels like a strong fit for developers who want an AI coding agent without getting locked into one model or one editor. I like that it works in the terminal, desktop, and IDE, so it can fit into different workflows instead of forcing one setup. The model flexibility is a big win. Being able to use 75+ providers, local models, GitHub Copilot, or ChatGPT Plus/Pro makes OpenCode feel more open and customizable than a lot of coding assistants. I also like the LSP support and multi-session workflow. For real coding work, it helps when the agent understands the project better and can run multiple threads of work in parallel.
  • Easy to install Easy to use Free models available with nearly no limits New models commonly get added for free

Cons

  • OpenCode is still something I would supervise closely. Any coding agent that can modify files, reason through projects, and run workflows needs clear review, tests, and good developer judgment.
  • CLI only
