It's a split decision.
Aider is a free, open-source terminal client that connects to cloud or local LLMs and works directly with Git. It suits developers who want to keep AI work close to their repository and choose their model provider. Cursor is a desktop app and CLI with cloud agents, Slack and GitHub workflows, and paid plans that scale with usage. Choose it when you want agents to plan, test and hand off work for review. Cursor's third-party models can add separate API charges.

02Pricing at real usage
Aider has no subscription tiers: the pricing page lists Open Source (Free) at $0 per month. You bring your own LLM API keys or use local models, so cloud-model charges sit outside Aider. Aider does not publish seat or usage limits; your bill depends on the model provider and how much you call it.
Cursor has a Free plan with limited agent and Chat requests. The pricing page lists Plus at $8 per month, Premium at $30, Super at $100 and Ultra at $200. Premium, Super and Ultra include 4x, 15x and 50x more usage than Plus. Teams starts at $30 per user per month; Enterprise is custom. Third-party models are billed separately at API list price, and usage top-offs are available after an allowance runs out. Check how your intended models and workload fit the allowance.
03API, SDKs and integration
Aider is a terminal pair-programming client that connects to cloud LLMs or local models. Its homepage gives a Python pip install setup and model-specific CLI commands for DeepSeek, Claude 3.7 Sonnet and OpenAI o3-mini, and says it can connect to almost any LLM. It maps a codebase, edits files, commits changes through Git, and can run linters and tests. Its documentation covers installation, usage, configuration, connecting to LLMs and troubleshooting. The homepage lists Python, JavaScript, Rust, Ruby, Go and other languages, but does not identify a vendor SDK matrix.
Cursor combines a desktop coding agent and CLI with cloud agents and workflows in Slack and GitHub. Developers can choose models from OpenAI, Anthropic, Gemini, SpaceXAI and Cursor's Composer. The homepage describes agents that plan, write, test and demo work, and workflows that open or review pull requests. It does not specify a public API or SDKs in the product overview. Treat Cursor as an application and agent workflow, not a documented embedding API.
04Open source, self-hosting and lock-in
Aider is free and open source under Apache 2.0, and is self-hostable. It runs from a terminal or IDE/editor, works on your repository and uses Git commits; it can also connect to local models. That gives teams a way to keep inference local and review or revert edits with Git, while cloud-model calls still go to the selected provider. Aider's product pages do not describe a specific data-export feature, but code changes appear in the working tree and Git history.
Cursor's open-source licence and self-hosting options are not published by the vendor. Its desktop app, CLI and cloud agents form a workflow that includes Slack and GitHub. The homepage describes cloud agents and pull-request review, but not a data-export path. Before adopting it, confirm how agent state, prompts and project configuration can be exported, and test migration with your normal Git-based repository workflow.
Questions people ask
Is Aider or Cursor better for local models?
Aider is the clearer fit if local-model support is a requirement: its homepage says it connects to local models as well as cloud LLMs. Cursor's homepage lists model providers but does not describe local-model support. Confirm model compatibility with your chosen setup before committing to either tool.
Does Aider cost anything to use?
Aider's pricing page lists its open-source plan at $0 per month, with no subscription tiers. You bring your own LLM API keys or use local models, so cloud-model charges may still apply through the provider. Aider does not publish seat or usage limits.
