Windsurf 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.
The projects

What you give up either way
- Proprietary high-performance models (SWE-1.6 / SWE-1.7) bundled by the vendor
- Integrated cloud agents and hosted Devin Cloud
- Built-in enterprise admin features (SSO, VPC deploys, centralized billing)
- Vendor integrations marketplace and polished IDE experience
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Windsurf, and it does not prove anyone has run it for a month. How we decide.
