Greptile
Pros
- + Full-repo context found a downstream stale-read assumption outside the diff on my caching-TTL PR — the finding diff-scoped tools miss
- + Codebase Q&A located a second webhook-validation path in a legacy module after an hour of my manual searching failed
- + No seat fees on Pro: credits are shared org-wide, so scaling the team does not scale the bill linearly
- + Free for OSI-licensed open source, plus 500 credits/month for six months for pre-Series A startups
Cons
- - Credit costs vary 10x by review tier (Base 1, Apex 10), so careless tier policy gets expensive fast
- - Not a code-writing tool — understanding and review only; generation is thin
- - Pricing surfaces contradicted each other in 2026 (per-seat vs per-credit); confirm live terms before budgeting
- - Self-hosting is Enterprise-only
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
