Switching from
What to check before leaving each one, and the options worth knowing.
Claude Code alternatives: what to check before switching
The real question is lock-in. Eight things to check before switching coding agents, the options worth knowing, and head-to-head comparisons.
CodexCodex alternatives: keep GPT, add every other model
Looking for an OpenAI Codex alternative? What to check, the options, and how to keep your ChatGPT plan while adding Claude, Gemini, DeepSeek and local models.
Claude CoworkClaude Cowork alternatives: an agent desktop that runs any model
Looking for a Claude Cowork alternative? What Cowork does, what to check, the options — and where OHarness's desktop agent fits, with any model and your own key.
Head to head
One tool at a time: where it wins, where OHarness does, and who should pick which.
OHarness vs Claude Code
Choose Claude Code if you work with Claude models and want the best-supported tool for them, with an OS sandbox and usage included in a Claude plan. Choose OHarness if you want the same kind of agent on any model — OpenAI, Gemini, DeepSeek or a local one — switching mid-session without losing the conversation.
OHarness vs OpenCode
Choose OpenCode if you want a mature, fully open source terminal agent with the widest set of subscription logins. Choose OHarness if switching models mid-session without converting history, or one engine behind terminal, browser and desktop, matters more.
OHarness vs OpenAI Codex CLI
Choose Codex CLI if you mostly use OpenAI models, want an OS-level sandbox with the network off by default, or want usage included in a ChatGPT plan. Choose OHarness if you want Anthropic, Gemini, DeepSeek and Chat Completions endpoints first-class in the same session.
OHarness vs Aider
Choose Aider if you want pair programming built around git — automatic commits, `/undo`, a repository map — with a light footprint. Choose OHarness if you need an agent with MCP tools, subagents, permission rules and a browser or desktop UI.
OHarness vs Cline
Choose Cline if you want the agent inside VS Code or JetBrains with Plan/Act modes and checkpoints. Choose OHarness if you work from the terminal or browser, switch vendors mid-task, and want deny rules that hold in every mode.
OHarness vs Gemini CLI
Choose Gemini CLI if you work on Gemini and want its free tier — 1,000 requests a day with a Google account — and built-in sandboxing. Choose OHarness if you need Claude, GPT, DeepSeek or local models alongside Gemini in one session.
OHarness vs DeepSeek Harness
Choose DeepSeek Harness if you want to take the agent runtime itself apart — it is MIT licensed, the source is public, and every piece is a plugin — and can live with a developer preview. Choose OHarness if you want a coding agent to use every day, on any model, in the terminal, browser or desktop.
