Cursor
Pros
- + Codebase context is the deepest I have tested — multi-file refactors arrive as coherent changes across routes, tests and types
- + The X Subscription bundles Grok, Cursor and X Premium: Premium at $30/mo replaces what xAI says was $90/mo of separate plans (x.ai/news/x-subscription)
- + Agent surface is broad: Cloud Agents, Automations, Bugbot PR review, CLI, Cursor SDK and an iOS app behind one router
- + Legacy subscribers keep their old plans and prices — the migration is optional, with prorated refunds on switching (cursor.com/help)
- + Familiar VS Code base means your extensions, keybindings and workflows come along
Cons
- - Acquired and re-platformed: new plans bill through grok.com with a Grok-weighted model lineup, and switching from a legacy plan is permanent
- - Plus at $8/mo is a teaser — no Auto, Cloud Agents, Automations or Bugbot; professional work needs Premium at $30/mo or above
- - Proprietary code goes to Cursor's servers during indexing and agent runs unless you configure privacy controls
- - Third-party models bill at API list price from prepaid credit, so costs outside the included pool are hard to predict
- - Two coexisting billing systems and two plan ladders make the real cost of a given workload hard to compare
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
