Aider
Pros
- + Free and Apache-2.0 — in my cost tracking a 40-prompt Sonnet session cost about the price of a coffee in API tokens
- + Repository map handled a 7-caller rename in one pass on a 100k-line codebase, beating a paid agent that needed two rounds
- + BYOK with local-model support via Ollama: I completed a refactor fully offline with no code leaving the machine
- + Every change is an auto-committed git commit with a generated message, making each AI step individually revertable
Cons
- - No GUI, no hosted workspace, no preview — terminal comfort is a hard prerequisite
- - No team or enterprise layer: no SSO, audit logs, shared config server or vendor support contract
- - Auto-commits fragment history unless you configure around them
- - Unbounded API spend: heavy all-day use can cost more than a flat-rate subscription tool
Zed
Pros
- + Performance held up where it counts: instant startup and fluid multi-cursor editing on a large Rust repo in my testing, with the AI panel closed and no model configured
- + Free Personal plan is genuinely livable — 2,000 accepted edit predictions lasted several days of heavy editing in my runs, and unlimited BYOK/local-model usage carries no Zed markup
- + Agent Client Protocol runs external agents (Claude Code, Codex CLI) as first-class citizens inside Zed's UI with thread-level change review
- + Native collaboration with live cursors, conflict-free sync and in-project screen sharing worked cleanly across two machines in my test
- + Real cross-platform support now: macOS, Linux and official Windows since October 2025 (DirectX backend) — the old 'Mac only' limitation is gone
Cons
- - Extension catalog is hundreds, not tens of thousands — VS Code-specific extensions may not exist
- - Pro's $5 token allowance is not a spending ceiling: overage bills at provider list price +10% with a default $10/month incremental cap
- - Business plan lacks SSO, SAML and SCIM (planned, not shipping at time of writing), blocking some enterprise rollouts
- - Zeta edit prediction was strong on repetitive refactors but weak on novel logic in my runs — I stopped accepting after a few misses
- - Remote development demands exact local/remote version matches; Windows needs a DirectX 11 GPU and is slower under VM display emulation
