Aider vs OpenCode
Compare Aider and OpenCode by workflow, pricing, privacy, model support, and best use cases.
Aider
Choose Aider when you want an open-source, terminal-native coding agent that edits a real Git repo and lets you control the model provider. Choose a hosted AI IDE or extension instead if you need polished inline completions, team administration, or a visual product-building workflow.
OpenCode
Choose OpenCode when you want an open, terminal-native coding agent with broad provider choice, local model support, and GitHub workflow automation. Choose a hosted AI IDE or commercial coding assistant instead if you want a more polished out-of-the-box editor experience, bundled billing, or heavy team administration.
Key Differences
Workflow
Aider is a terminal-native, open-source AI coding agent for developers who want direct Git-based code editing with flexible model choice.
OpenCode is an open-source, provider-agnostic AI coding agent for developers who want Claude Code-style terminal workflows without being locked to a single model provider.

Pricing Comparison
Aider
- Open Source$0
Aider is free and open source. Users run it locally and bring their own model/API access.
- Bring Your Own API KeyUsage-based
Costs depend on the chosen LLM provider, model, context size, and usage volume.
- Local Models$0
Can connect to local models through Ollama or OpenAI-compatible local endpoints; hardware and model quality determine performance.
OpenCode
- Open Source$0
MIT-licensed open-source coding agent. Users can install and run OpenCode locally with their own model credentials.
- Bring Your Own ModelUsage-based
Use external LLM providers through API keys, GitHub Copilot login, ChatGPT Plus/Pro login, local models, or OpenAI-compatible endpoints.
- OpenCode ZenPay-as-you-go
Optional curated model gateway with per-token pricing and usage limits for teams or individuals.
- OpenCode Go$5 first month, then $10 / month
Optional subscription for reliable access to selected open coding models, designed especially for international users.
- EnterpriseCustom
Per-seat enterprise plan with centralized config, SSO integration, internal AI gateway routing, and implementation support.
Privacy & Security
Aider
Aider runs locally in the user's environment, but code and prompts may be sent to the selected LLM provider unless a local model is used. Privacy therefore depends on model choice, API provider terms, configuration, ignored files, and whether the user includes sensitive files, secrets, images, web pages, or command output in chat context.
OpenCode
OpenCode states that it does not store code or context data by default, with processing happening locally or through direct API calls to the selected AI provider. The main exception is the optional /share feature, which uploads conversation data to OpenCode-hosted share pages and creates public links. Privacy depends on provider choice, local model usage, enterprise gateway routing, share settings, and whether sensitive files, secrets, or production data are included in context.
