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
Trae
- +Free and cheap frontier-model access (Claude, GPT, DeepSeek) with aggressive low-cost tiers
- +Familiar VS Code base with low switching cost
- +Broad agentic spectrum (Builder plus SOLO) with MCP support
- -Serious privacy and telemetry concerns from ByteDance ownership (reported by researchers and journalists), likely an enterprise non-starter
- -Heavy resource usage reported relative to VS Code
