TPT Anvil

The open-source, privacy-first AI development environment.

Status: pre-alpha — active development

Anvil is a fully open-source alternative to GitHub Copilot and Cursor. Everything runs on your machine — your code never leaves.

GPU acceleration — CUDA, ROCm, WebGPU
Codebase-aware context — Tree-sitter AST + hybrid BM25/vector semantic search
Cloud fallback — OpenAI, Anthropic, OpenRouter, or any OpenAI-compatible endpoint
VS Code extension — chat panel, slash commands, diff-based edits
JetBrains plugin — IntelliJ IDEA, PyCharm, GoLand, and all JetBrains IDEs
Privacy-first — 100% local by default, zero telemetry
