Amazon Q Developer
Pros
- + Account-aware assistance: bill analysis, resource diagnostics and well-architected guidance inside the AWS Console — nothing generic matched it
- + Code transformation agents for Java upgrades and .NET porting produced reviewable plans; 1,000 free lines/month for validation
- + Security scanning (50 scans/month free) flagged hardcoded secrets and vulnerable dependencies in my runs, with reference tracking and public-code suppression
- + Per-user Pro pricing ($19) with IP indemnity, IAM Identity Center and admin dashboards was straightforward procurement for AWS shops
- + Existing customers retain IDE plugin access through the transition window with critical bug fixes
Cons
- - Being sunset: sign-ups blocked since May 15, 2026 and IDE plugins lose support April 30, 2027 — AWS directs new users to Kiro
- - Free tier's 50 agentic requests per month is shared across chat and coding and drains fast; hard stop at the cap
- - Pro's request limit (~1,000 user requests/month, FAQ-only) has no overage purchase — a hard ceiling mid-month
- - Code generation trailed the leading assistants in my comparisons; value was heavily AWS-dependent
- - Newest models pulled from Q Developer in May 2026, and GitHub/GitLab transformation integrations were deprecated in late 2025/early 2026
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
