Comparison
Authreads versus a self-hosted identity server
Running Keycloak, Ory or FusionAuth yourself compared with a managed multi-tenant identity platform — control and cost against operational load.
The short answer
Authreads and a self-hosted identity server, in one paragraph
Self-hosting gives you total control and, on the free editions, no per-user licence, in exchange for owning the operation: upgrades, availability, key rotation, backups and the 3 a.m. page when login is down. The trade is not licence cost against subscription cost; it is engineering attention, and identity is a component where attention is expensive precisely because it is rarely needed until it is urgent.
What a self-hosted identity server is built around: Identity servers you run yourself — open-source projects such as Keycloak and Ory, or free self-hostable editions such as FusionAuth Community — where the software costs nothing to obtain and the operation is entirely yours.
We describe what an alternative is built around, never its pricing, its limits or whether it supports a given feature today — those change on their schedule, not ours, and a wrong claim here would cost more than this page earns. The positioning above was last checked against a self-hosted identity server's own public documentation on . Check their current documentation before making a decision on it.
Being fair about it
Where a self-hosted identity server is the better choice
Listed first, and meant literally. If one of these is your situation, take it as advice.
- Control. You can change anything, pin any version, and run it anywhere — including air-gapped.
- Data residency. If the data genuinely cannot leave your infrastructure, self-hosting answers that in a way no managed platform can.
- No per-user pricing on the free editions (some projects sell paid tiers — check their current pricing). At very large user counts this is a real and durable economic argument.
- Maturity. Several of these projects have been in production for a long time across an enormous range of deployments.
Where we differ
What Authreads is built around instead
Design decisions with real costs attached. They are the reason to look at us, and the reason not to.
Our limits
What we cannot do today
Same typeface as everything else on this page. A comparison that hides this section is not worth reading.
- You cannot self-host Authreads. If the requirement is that identity runs inside your own infrastructure, this is not a platform that can meet it and no amount of conversation will change that.
- Less configurability by design. A self-hosted server can be bent to almost any shape; we deliberately do not expose that surface.
- Authreads holds no SOC 2 or ISO 27001 certification today and does not claim one. If your procurement process requires an audit report at signature, that is a hard blocker and we would rather you know now.
- We publish no customer names, customer count or uptime SLA, because none can be stated honestly yet. Several alternatives can point at years of production scale; we cannot.
Every capability on this site appears on /roadmap in one of three states — Available, In progress, or Planned — with no dates and no internal phase numbers.
The short version
Consider Authreads if…
You have counted the real cost of operating identity — upgrades, availability, on-call, key rotation — and would rather spend that attention on your own product.
Questions people ask before switching
Can we self-host Authreads?
No. It is a managed platform and there is no self-hosted distribution. If self-hosting is a hard requirement, one of the open-source servers is your answer and we would rather say that plainly than dress it up.
Is self-hosting cheaper?
In licence terms, yes. In total terms it depends on what an engineer's attention is worth in your organisation and how much of it identity consumes — which is very little most months and a great deal in the month something breaks. Count on-call, upgrades, backups and key rotation before comparing.
What happens to our data?
Data handling, retention windows and sub-processors are set out on /trust and /sub-processors. Contact-form submissions on this site are retained for exactly 365 days and then deleted automatically, and that window is enforced rather than described.
Compare something else
Authreads as an Auth0 alternative
Your product serves many customers, one tenant reading another's data would be the worst thing that could happen to you, and you would rather that be impossible than configured.
Authreads as a Clerk alternative
You are past the first-login problem and into the harder one: many tenants, per-tenant policy, and machine traffic that needs credentials of its own.
Authreads as a WorkOS alternative
Tenant isolation and machine identity are your hard requirements, and enterprise SSO is something you will need later rather than something a contract is blocked on this quarter.
Authreads as a Stytch alternative
The authentication methods you need are ones we already support, and the difficulty is the tenant model behind them.
Authreads versus building authentication yourself
You have more than one tenant, a security review coming, and a product that is not an identity product.
Tell us what you're actually deciding between
We will tell you honestly when another platform is the better answer for what you're building. That happens more often than a comparison page usually admits.
