OpenCode offers free models without an account. Its paid plans are Go at $10/month and Go Plus at $40/month; the pricing page lists no annual billing.

Tabby Community costs $0 per user/month for up to five users and includes unlimited tab completion. Team is $19 per user/month for up to 50 users; Enterprise is custom-priced and billed annually. Tabby Cloud bills by LLM token cost, includes $20 in monthly credits and automatically bills above $10. Smaller amounts are billed at month-end. Compare OpenCode’s estimated request allowances with Tabby’s token-based billing against your model and task usage.

OpenCode offers a desktop app, a terminal UI and an SDK for driving sessions from scripts, CI jobs and tools. Its docs provide terminal installation commands for curl, npm, bun, Homebrew and paru. The product pages do not name SDK languages. Integrations include more than 200 model providers, local models, MCP servers and services such as GitHub, Linear, Figma, Sentry, Notion, Slack, Supabase and Stripe. Plugins can hook into events; custom agents can have their own prompts, models and tools.

Tabby’s integration model centers on IDE features: code completion, an Answer Engine and inline chat. The homepage lists VS Code, Neovim, IntelliJ, Eclipse, Android Studio and other IDEs. Data connectors can use documentation, configuration files and external APIs for project context. Tabby also links to docs, but its product pages do not name an SDK or language-specific client. For an agent that you want to drive from code, OpenCode has the clearer SDK path. For IDE-centered completion and chat, Tabby lists the broader set of editor integrations.

Both products identify as open source and support self-hosting. Check each repository’s licence before redistributing or embedding either tool; the product pages do not name the licence terms. OpenCode works on your machine and connects to local models or providers, while Tabby supports on-premises deployment and says it can run without external database management systems or cloud services.

The products expose different migration surfaces. OpenCode has sessions, custom agents, plugins and MCP connections; Tabby focuses on IDE assistance and data connectors. Moving between them may mean rebuilding prompts, tools, connectors and editor workflows rather than transferring a shared configuration. Neither vendor publishes a data-export procedure on its product page. Before adopting either, ask how to export session history, project context and configuration, and verify what data your chosen deployment stores.
