Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aider

  • Requires comfort working in a terminal rather than a graphical IDE
  • Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
  • Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
  • Lacks a built-in autonomous multi-step task runner comparable to agent-style products

Cursor

  • Cannot work fully offline; AI features require internet connection
  • Local models require requests to route through Cursor's backend, not true localhost support
  • Free tier capped at 2,000 completions per month
  • Codebase indexing uploads code chunks to compute embeddings, with file caching handled server-side

Answered from the vendors’ own pages

Aider: Is Aider free to use?

Aider itself is free and open source, released under the Apache 2.0 license. Users must separately supply and pay for API access to the LLM they choose to use with it.

Source
Cursor: What's included in Cursor's free tier and what are its limits?

The free Hobby plan provides 2,000 completions per month and 50 slow premium requests, with access to basic autocomplete features. Codebase-wide indexing and the Composer multi-file editor are not available on the free plan.

Source
Aider: Which LLMs can I use with Aider?

Aider connects to OpenAI, Anthropic, Gemini, GROQ, DeepSeek, Ollama, Azure, Cohere, xAI, GitHub Copilot, Vertex AI, Amazon Bedrock, OpenRouter and most other LLM providers via API keys.

Source
Cursor: Does Cursor require an internet connection to edit code?

While Cursor can open and edit files locally, its AI features including autocomplete, chat, agents, and codebase-aware reasoning require internet access to cloud-hosted models.

Source
Aider: Can I use Aider for free without paying for an LLM API?

Yes, Aider can be used at no cost through OpenRouter's free model access (subject to daily usage limits) or Google's Gemini 2.5 Pro Exp, which the docs note performs well without a paid API key.

Source
Cursor: Can I use Cursor with local models running on my machine?

Cursor can integrate with local models, but requests still route through Cursor's backend for prompt building. True localhost mode without external endpoints is not supported. The paid plan ($20+/month) is required to use local models.

Source
Aider: How does Aider handle version control?

Aider automatically stages and commits each change it makes to a connected git repository, generating a descriptive commit message for every edit so changes stay reviewable and reversible.

Source
Cursor: What privacy controls does Cursor offer?

Cursor offers Privacy Mode (enabled on paid Team plans) which prevents customer data from being used for model training, with zero data retention agreements with all AI providers. When disabled, Cursor may use codebase data to improve features.

Source
Cursor: What are the differences between Pro and Pro+ plans?

Pro ($20/month) includes unlimited completions and 500 fast premium requests, while Pro+ ($60/month) provides 3x those request limits, priority feature access, and extended Agent capabilities.

Source
Cursor: Does Cursor support SSO and on which plan?

SSO with SAML/OIDC is included on Teams Standard ($40/user/month) and higher plans, with full team administration and audit logs.
