Goose
Block's open-source coding agent, BYOK across multiple model providers, with MCP support and a permissive license; the most cited fully-open agent platform in 2026.
Block’s open-source agent framework, Apache 2.0governanceA permissive open-source license used by most open-weight model releases (Llama from 4 onward partial, Qwen, Mistral, DeepSeek, Falcon), allowing commercial use without acceptable-use restrictions. Open full entry licensed. Goose ships a CLI and a desktop app, supports BYOK across Anthropic, OpenAI, Google, GroqsiliconAn AI inference company with custom deterministic LPU chips and a hosted inference service that achieves extremely low time-per-token (1000+ tokens/sec on 70B models). Open full entry , OllamaruntimeA local inference runtime that wraps llama.cpp with a Docker-style developer experience, the easiest path to running open-weight models on a personal machine. Open full entry , and others, and integrates with MCPprotocolsAn open protocol from Anthropic that standardizes how language models discover and call external tools, data sources, and prompts via a small JSON-RPC interface. Open full entry servers for extending tool surface. The original use case was coding agent workflows; the architecture is general enough for any tool-using agent.
Goose’s relevance is partly its openness (one of the few fully open-source agent frameworks competitive with proprietary alternatives like Claude Code or Cursor) and partly Block’s commitment to it as a product line. The fact that a major fintech is building open-source agent infrastructure is itself a meaningful signal.
