Pier
What Pier is
Pier is a terminal-based coding agent for Windows, macOS, and Linux. It reads repositories, indexes codebases, plans changes across files, runs commands, and ships code, with chat assistance and terminal access included. Plan mode researches a project and presents a read-only plan before execution needs approval. File changes are gated for review, and commands are shown before they run. Users can select models from providers including Sarvam, DeepSeek, GLM, Kimi, Qwen, and Codestral, or use Pier Hybrid routing. Pier runs as a single binary under the user’s account without a background filesystem-watching service. It says source code is not stored on its servers, although subscription prompts pass through its servers to the selected model platform. Conversation threads sync by default, with a local option. The free account supports personal Sarvam AI or OpenRouter keys. Pro costs $5 a month, Max costs $20 a month, and Usage pack costs $5 a month as a top-up.
