The short version

Only Atlantis has a free tier, so it costs nothing to try first.
Each has a real cost: Atlantis there is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.; WorkOS authKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Atlantis

There is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.
The security surface is inherently sharp, because it is an internet-reachable webhook endpoint that executes applies with privileged credentials, gated by pull request comment authorisation that is coarse next to a real policy engine.
It is stateful, holding a working directory and lock database on local disk, so high availability and horizontal scaling are awkward and you own upgrades, webhook plumbing, secret rotation and the host itself.
It lacks the features that distinguish the commercial alternatives, with no native drift detection, no cost estimation, no managed state interface and no policy engine beyond the Conftest integration.
Terragrunt and monorepo layouts are not first-class, requiring hand-written custom workflows and repository configuration that becomes a growing maintenance burden as the number of repositories increases.

WorkOS

AuthKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month
Per-connection pricing for SSO and Directory Sync ($125–$50 each) scales poorly for enterprises with many identity providers
Audit logs require separate subscription at $125/month per SIEM connection or $99/month per 1 million events
Radar fraud protection billed separately at $100/month per 50,000 additional checks beyond 1,000 free checks
Custom domain feature requires $99/month subscription
Requires annual commitment for SLA and support guarantees; pay-as-you-go tier lacks uptime guarantee

Answered from the vendors’ own pages

No. It runs as a series of LF Projects under the Linux Foundation and is maintained by volunteers. There is no vendor to buy support from and no service level agreement.

WorkOS: Does WorkOS support SCIM provisioning?

Yes. WorkOS supports SCIM provisioning integration with systems like Okta and Entra ID for automated user management.

Source

Atlantis: What does it not do that a paid platform does?

Drift detection, cost estimation, a managed state and run interface, and a real policy engine. Atlantis does pull request plan and apply well and stops there.
