Cursor alternatives
2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- Cursor’s proprietary model(s) (Grok 4.5 and Cursor-hosted models)
- Built-in enterprise features (pooled usage, SSO/SCIM, audit logs, invoicing)
- Hosted cloud agents, marketplace plugins, and native desktop integrations
- SOC 2 / vendor compliance guarantees and vendor-provided privacy controls
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Cursor, and it does not prove anyone has run it for a month. How we decide.
