Analyst summary
Cursor
Cursor (Anysphere) is a fast-moving AI-native code editor with strong privacy-mode defaults on Business plans and zero-retention contracts with upstream model providers. Its small company size and dependency on third-party LLM providers are the primary risk factors.
Strong choice for dev teams that value velocity and privacy-mode defaults; not yet a fit for heavily regulated buyers.
Aider
Aider is a popular open-source (Apache 2.0) terminal-based AI pair programming tool, originally created by Paul Gauthier and now maintained as Aider-AI on GitHub (~44k stars). It is not a SaaS company — there is no commercial entity offering SOC 2, HIPAA, or DPAs. Risk is determined by which LLM provider you point it at, not by Aider itself.
Solid as a developer tool when you've already approved the LLM provider; treat security and compliance as your problem, not Aider's.
