Full Comparison
| Criterion | Amp | OpenCode |
|---|---|---|
| Starting price | Megawatt $20 / month Includes $20 of agent usage and 750 hours of orbs. Gigawatt $200 per month. Students and teachers $10 per month. Unconstrained is pay-as-you-go at API pricing, with the option to bring your own inference keys. | Free, MIT licence You bring your own provider keys and pay them directly. The optional OpenCode Zen gateway is pay as you go per million tokens and includes several free models. |
| Free trial | Not stated | Free open-source agent |
| Commercial use | Yes | Yes, MIT licence |
| Output | Autonomous, multi-step coding across the terminal, editors and Slack | Agentic coding in a terminal, a desktop app or an IDE |
| API | N/A | Local server with a TypeScript SDK |
| Where it runs | CLI, VS Code and compatible editors (including Cursor and Windsurf), Neovim, Zed, the web and Slack | Terminal, a desktop app for macOS, Windows and Linux, and IDE extensions; open source under the MIT licence, installed through npm, Homebrew, Scoop, Chocolatey, Arch, Mise, Docker or a binary |
| Inline completions | No, the Amp Tab completion engine was retired at the end of January 2026; Sourcegraph points to Cursor, Copilot or Zed for inline completions | No, OpenCode is driven by prompts rather than by suggestions as you type; its language-server integration feeds diagnostics back to the agent instead of offering inline completions |
| Agent mode | Yes, an autonomous agent that reads code, runs tests and commands and edits files across multi-step tasks | Yes, an autonomous coding agent with several sessions running in parallel and the option to share a session |
| Model choice | Yes, Amp routes between frontier and fast models per task; an optional linked ChatGPT subscription extends high-mode usage | Yes, more than 75 providers through Models.dev with your own keys, plus local models through Ollama, LM Studio or llama.cpp and any other OpenAI-compatible endpoint declared in opencode.json |
| Data control | Enterprise adds SSO, directory sync and admin controls | Provider keys are stored locally in the user's own auth file rather than on a server, the project states it does not store your code or context data, and local models keep the work on your machine |
| Ecosystem fit | Sourcegraph; integrates with existing editors and Slack rather than replacing them | Terminal, desktop app and IDE extensions, with language servers and MCP servers configurable; the optional OpenCode Zen gateway supplies models tested for coding agents |
| Deployment | Cloud (SaaS), Browser-based | Cloud (SaaS), On-premise |
| Support | more entries Email helpdesk, Community forum | Community forum |
| Onboarding | Documentation and knowledge base | Documentation and knowledge base |
| Company size | more entries Freelancers, Small and mid-sized, Enterprise | Freelancers, Small and mid-sized |

The trade-offs
Strengths and Limitations
Amp
Strengths
- Agent-first workflow that spans the terminal, multiple editors, the web and Slack
- Routes between frontier and fast models instead of locking to one
- Thread sharing makes agent work collaborative across a team
Limitations
- Usage-based pricing can be harder to predict than a flat seat price
- Built around an autonomous agent rather than inline autocomplete
OpenCode
Strengths
- MIT-licensed and free, with no restriction on commercial use
- More than 75 model providers plus fully local models, so no vendor lock-in
- One agent across terminal, desktop app and IDE
- Local server and TypeScript SDK for embedding the agent in other tools
Limitations
- You manage provider keys and pay model costs directly, so spend is harder to predict than a seat price
- Topping up OpenCode Zen credit adds a card processing fee of 4.4% plus $0.30 per transaction
- Zen model prices span a wide range, from $0.05 to $180 per million tokens depending on the model
