About

Reasonix is an open source coding agent designed for long autonomous sessions that remain readable, auditable, and reversible. One local engine powers four interfaces: terminal, desktop app, browser, and ACP-compatible editors, with sessions, permissions, skills, and MCP servers shared across them. Plan mode holds every write until the proposed steps are reviewed and approved, while reads, writes, and shell commands are separately gated and constrained by a workspace sandbox. Each turn creates a checkpoint outside Git, allowing users to rewind a long run without affecting commit history. MCP support over stdio, SSE, and streamable HTTP merges external tools into one registry, while Markdown skills and isolated subagents extend the agent without requiring a fork. Reasonix maps a codebase once and keeps that map throughout the session, letting users queue tasks, review diffs, and resume work without losing context.

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
