Aider
- +Fully open source (Apache-2.0) and free; you only pay your chosen model provider
- +Git-native: every AI change is a reviewable, revertible commit
- +Model-agnostic with a repo map that scales to larger codebases
- -Terminal-only with no GUI or IDE-native experience for those who want one
- -Runs locally and edits real files, so a human must review every change
Tabby
- +True self-hosted/on-prem, no cloud or database dependency; runs on consumer GPUs for air-gapped or regulated environments
- +Open source (Apache 2.0 core), model-agnostic, with an OpenAI-compatible API
- +Actively maintained with broad IDE coverage, repo-aware completion, and an Answer Engine
- -Capability ceiling versus cloud incumbents: fundamentally completion, chat, and retrieval
- -Agentic workflows and MCP are roadmap or private preview, not generally available
