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
Cline
Pros
- + Apache-2.0 licensed agent core with roughly 70,700 GitHub stars - auditable and forkable
- + Free for individuals; you pay only your model provider for inference, so I can run cheap models for mechanical edits
- + Plan mode plus diff-per-edit approval kept my interventions to two on a 12-file TypeScript refactor in my test
- + Real terminal integration: it ran my test suite, read raw compiler output, and fixed a missing import unprompted
- + Checkpoints restore files without killing the conversation - one rollback in my session saved an hour of re-prompting
Cons
- - JetBrains plugin is explicitly not open-sourced, which undercuts the fully-auditable pitch
- - Metered inference means long watch sessions on noisy dev-server logs inflate your provider bill quickly
- - No hosted team features: no seat management, spend dashboards, or SSO out of the box
- - Requires bringing your own API keys - newcomers face provider setup before their first edit
- - Depth of polish still lives in VS Code; CLI and desktop are capable but younger surfaces
