Supabase Auth vs WorkOS for Next.js
Supabase Auth and WorkOS both answer the same question in a Next.js project: how do users sign in? Auth that ships inside Supabase, with users stored in your Postgres and row level security wired to the session. Auth aimed at teams selling to enterprises, where SAML, SCIM directory sync and audit logs are the actual requirement. Supabase Auth covers more of the ecosystem, so it survives a change of framework; WorkOS is the better fit while you stay where it is strongest.
Verdict
Supabase Auth covers more of the ecosystem, so it survives a change of framework; WorkOS is the better fit while you stay where it is strongest. For Next.js specifically, both are supported, so let the tradeoff above decide rather than the framework.
Pick Supabase Auth if
- ✓The user table is a Postgres table, so foreign keys to it just work.
- ✓Row level security policies read the session directly, pushing authorization into the database.
- ✓One vendor for auth, storage and database keeps the moving parts low.
Pick WorkOS if
- ✓SAML and SCIM are first-class, not an afterthought priced behind sales calls.
- ✓Directory sync keeps enterprise customer user lists current automatically.
- ✓Audit logs and admin portal remove a common enterprise procurement blocker.
| Comparison | Supabase Auth | WorkOS |

| Pricing shape | Included with the Supabase project you already pay for, with additional cost only at higher active-user tiers. | Free up to a sizable user count for standard auth, with enterprise connections priced per connected organization. |
| Frameworks | Next.js, SvelteKit, Nuxt, React Native, Expo, Flutter | Next.js, Laravel |
| In one line | Auth that ships inside Supabase, with users stored in your Postgres and row level security wired to the session. | Auth aimed at teams selling to enterprises, where SAML, SCIM directory sync and audit logs are the actual requirement. |

Supabase Auth
Strengths
- ✓The user table is a Postgres table, so foreign keys to it just work.
- ✓Row level security policies read the session directly, pushing authorization into the database.
- ✓One vendor for auth, storage and database keeps the moving parts low.
- ✓Client libraries for web and mobile share the same session model.
Tradeoffs
- ✗Bundled with Supabase, so adopting it usually means adopting the whole platform.
- ✗Auth schema lives in a managed namespace you cannot freely reshape.
- ✗Row level security is powerful but easy to get subtly wrong.
- ✗Self-hosting the full stack to escape the cloud is a real operations project.
WorkOS
Strengths
- ✓SAML and SCIM are first-class, not an afterthought priced behind sales calls.
- ✓Directory sync keeps enterprise customer user lists current automatically.
- ✓Audit logs and admin portal remove a common enterprise procurement blocker.
- ✓Normalizes many identity providers behind a single consistent API.
Tradeoffs
- ✗Built for business-to-business, so consumer social login is not the sweet spot.
- ✗Per-connection enterprise pricing gets steep as you add corporate customers.
- ✗Identity lives with WorkOS, adding a hard external dependency to every login.
- ✗Overkill and over-configured if you never sell to companies with an IT department.
Same pair, different context
Frequently asked questions
Is Supabase Auth or WorkOS better in a Next.js project?
Neither is better in the abstract. Supabase Auth covers more of the ecosystem, so it survives a change of framework; WorkOS is the better fit while you stay where it is strongest. The wrong choice here is usually recoverable, so weight speed of decision over certainty.
What is the main drawback of Supabase Auth?

What is the main drawback of WorkOS?
Built for business-to-business, so consumer social login is not the sweet spot. Per-connection enterprise pricing gets steep as you add corporate customers.
Do Supabase Auth and WorkOS both support Next.js?
Yes, both list support for Next.js, which is why this comparison exists as a Next.js page. Next.js has two routing systems that look similar in code but behave completely differently, and most model training data blends them.
