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
Claude Code
Pros
- + Handles multi-file refactors end to end — in my 40-file migration it found all 11 call sites and greened the test suite without me touching code
- + Prompt caching makes long API sessions affordable: I measured 88% savings on a 170-turn session versus uncached billing
- + Hooks, subagents and CLAUDE.md give real control over behavior; my auto-format hook eliminated formatting noise entirely
- + Everything lands in git, so reviewing agent work is the familiar diff workflow rather than a trust exercise
Cons
- - No free tier — the floor is a $20/month subscription or a funded API key at time of writing
- - Token billing punishes restart-heavy habits: compacts break the cache and I saw per-turn cost jump from $0.11 to $0.29 after a restart
- - Terminal-first design will not fit teams wanting a visual or browser-based workflow
- - Occasionally edits code outside the scope of the request, adding review overhead on large PRs
