opencode
opencode is an open-source AI coding agent built by Anomaly (formerly known as the SST team, led by Dax Raad) that runs in your terminal, as a desktop app, or as an IDE extension. It reached 160,000+ GitHub stars and 7.5 million monthly developers as of May 2026, placing it among the most-adopted open-source coding agents. The core value proposition: bring your own API key from any of 75+ supported providers (Anthropic, OpenAI, Google, Mistral, or local models via Ollama), or connect your existing GitHub Copilot or ChatGPT subscription. You pay your provider directly — there is no intermediate markup. Two built-in agent modes switch with Tab: "build" executes code changes, "plan" explores and reads without modifying files. A $10/month "Go" plan provides generous access to curated open-source models (DeepSeek, Qwen, Kimi) without managing your own keys — useful as a cost-controlled entry point.
