What both publish
| Fact | OpenCode | Pier |
|---|---|---|
| Chat assistance | Yes | Yes |
| Codebase indexing | Yes | Yes |
| Coding agent | Yes | Yes |
| Data handling | OpenCode states that it does not store code or context data and that processing occurs locally or through direct provider API calls. | Pier says it does not store source code on its servers; on a subscription, prompts pass through its servers to the selected model platform, while a user's own API key sends prompts directly from the CLI to the provider. |
| Free plan | Yes | Yes |
| Model support | OpenCode supports 75+ LLM providers through AI SDK and Models.dev, as well as local models. | Users can select models from Sarvam, DeepSeek, GLM, Kimi, Qwen, Codestral, and other providers, or use Pier Hybrid routing. |
| Plan mode | Plan mode disables file-changing actions and lets the agent propose an implementation plan before build mode is enabled. | Plan mode investigates and presents a plan before making changes, with read-only research first and execution requiring approval. |
| Product | OpenCode is an open source AI coding agent for writing code in a terminal, IDE, or desktop app. | Pier is a terminal-based coding agent that reads repositories, plans across files, runs commands, and ships code. |
