Freebuff vs OpenCode (2026)

Freebuff

by Freebuff

OpenCode

by Anomaly Innovations, Inc

Pros

• ✓Free plan with no card and no API key, funded by text ads shown inside the product.
• ✓Runs in the terminal, a desktop app, the browser, on Android and on connected GitHub repositories.
• ✓Open source under Apache 2.0, with an MCP client and every plan price published.

Limitations

• –Prompt data is used for ad targeting, and models labeled for AI training may share prompts.
• –The Free plan runs DeepSeek V4.1 Flash models, and other models need a paid plan.
• –No security certifications are published, and the beta terms allow price and limit changes.

Pros

• ✓Developers can log in with GitHub Copilot or ChatGPT Plus or Pro to reuse existing subscription quotas, or connect any of 200+ providers including local models, with no separate API billing required.
• ✓Multi-session parallel agents run on the same project, and MCP client support covers local and remote servers with OAuth, so tools such as Sentry and Context7 connect inside the same workflow.
• ✓No code or context is stored, the agent is MIT licensed, and Anomaly Innovations publishes a SOC 2 Type 2 report through its Trust Center.

Limitations

• –Permissions start permissive: the Build agent edits files and runs shell commands without an approval prompt until a permission config is written, with only repeated identical calls, paths outside the project and reads of .env files gated.
• –Beyond the bundled free models, developers pay a provider directly or through Go or the OpenCode Console, and manage keys and accounts for each provider they use.
• –Enterprise pricing is quote-only, and the SOC 2 report and Data Processing Agreement are released through the Trust Center on request.
