WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
For larger companies, with more data and high-traffic tables, schema changes may happen less often, but they still need to worry about things like downtime caused by locking. They require long internal guides on performing schema changes correctly (e.g. GitLab, PayPal), custom tools (e.g. Meta, Square), and they often document incidents or near-incidents caused by schema migrations (e.g. GitHub, Doctolib, GoCardless).
From what I know, there is only one project that tries something close to this: the relatively recent Reshape. It uses Postgres views to expose the two versions of the schema and triggers to upgrade/downgrade the new data. It doesn’t do the constraints part as described above, but shows that this approach is possible. Combined with the Xata pull request based workflow, I think the ideal system described above is possible!
