Developers want an open-source terminal agent that works with any model provider and has no subscription lock-in. This guide maps your config files, walks a 4-step migration checklist and prices the seat delta for a 10-dev team.
01Migration brief
Developers want an open-source terminal agent that works with any model provider and has no subscription lock-in. Shifts from a fixed $20/mo seat to pay-as-you-go API tokens. (OpenCode Go is an optional $10/mo plan.)
Claude Code
Anthropic $20 per month · FreemiumClaude Code is a terminal-native agentic coding tool that integrates directly into your development environment to plan, edit, and test code across entire repositories. It operates as an autonomous agent that can handle multi-file refactors, bug fixes, and feature implementations by reading your codebase and executing shell commands with your approval.
OpenCode
Anomaly $10 per month · FreemiumOpenCode is an open-source AI coding agent that functions as a terminal-based interface, desktop application, or IDE extension. It supports multi-session workflows and allows users to connect to a wide range of LLM providers for customized coding assistance.

034-step checklist
- 01
Audit & export your Claude Code rulesClaude Code reads repo-level rules from CLAUDE.md. Convert them to AGENTS.md with the Rules Converter, then review the output before committing. Open →
- 02
Install & configure OpenCodeInstall OpenCode with `npm install -g opencode-ai`. Pricing: Freemium. Open ↗
- 03
Adapt your daily workflow (CLI Agents → CLI Agents)You trade a managed subscription for a bring-your-own-key setup — configure provider credentials and watch token spend instead of seat count. OpenCode is best for developers who need a versatile, privacy-focused AI coding agent that integrates directly into their terminal and supports custom model configurations.

Run a one-week parallel pilot, then reallocate seatsShifts from a fixed $20/mo seat to pay-as-you-go API tokens. (OpenCode Go is an optional $10/mo plan.) Keep Claude Code active for one sprint while OpenCode handles new tasks; cancel seats only after velocity holds. Open →
04Trade-offs
What you gain
- OpenCode is best for developers who need a versatile, privacy-focused AI coding agent that integrates directly into their terminal and supports custom model configurations.
- Unified background service shared across TUI, desktop, and web.
- Code Mode for converting MCP servers and OpenAPI endpoints into callable functions.
- Background subagents and long-running shell commands.
What you give up
- Claude Code is positioned for solo founders, indie hackers, and developers working in real-world codebases who need help with complex, multi-file engineering tasks like refactoring and bug fixing. — confirm OpenCode covers that before cancelling seats.
- OpenCode is not ideal for users requiring a closed-source, turnkey enterprise solution without any manual configuration, or those using legacy V1 plugins that are incompatible with the V2 architecture.
Running both together: Running both is mostly redundant — pilot OpenCode on one repo for a sprint, then pick one.

06FAQ
How do I convert my Claude Code rules to OpenCode?+
Claude Code reads CLAUDE.md and OpenCode reads AGENTS.md. Run them through the Rules Converter (https://ai.dosa.dev/tools/rules-converter?from=claude-md&to=agents-md) and review the output before committing.
Is OpenCode cheaper than Claude Code?+
Claude Code starts at Claude Pro ($20/mo); OpenCode has no listed per-seat plan. Shifts from a fixed $20/mo seat to pay-as-you-go API tokens. (OpenCode Go is an optional $10/mo plan.)
What do I lose when switching from Claude Code to OpenCode?+
Claude Code is positioned for solo founders, indie hackers, and developers working in real-world codebases who need help with complex, multi-file engineering tasks like refactoring and bug fixing. — confirm OpenCode covers that before cancelling seats. OpenCode is not ideal for users requiring a closed-source, turnkey enterprise solution without any manual configuration, or those using legacy V1 plugins that are incompatible with the V2 architecture.
Can I use Claude Code and OpenCode together?+
Running both is mostly redundant — pilot OpenCode on one repo for a sprint, then pick one.
