Authentication without the growth penalty._
Auth0 charges by the user and stops at sign-in. Appwrite Auth is open source, includes 200,000 monthly active users on Pro, and plugs straight into the database, storage, functions, and hosting in the same project.

- 3x
- OAuth providers

Pricing_
Grow your users, not your auth bill_
Auth0 paid plans start at $35/mo for just 500 users and climb with every login. Appwrite Pro starts at $25/mo with 200,000 users included. Slide to see the gap.
Auth0 B2C Essentials
$700/mo
About $70 per 1,000 users, from the first user.
Appwrite Pro
$25/mo
200,000 users included, then $3 per 1,000.
Auth0 list price for B2C Essentials, which starts at $35/mo for 500 users. Auth0 Free covers 25,000 users with a limited feature set, and pricing past 50,000 users is a custom quote. Appwrite Free covers 75,000 users, and Appwrite Pro includes 200,000.
Better together_
Identity that powers the rest of your backend_
Auth0 stops at identity. In Appwrite, the same users, teams, roles, and labels decide who can read a row, download a file, run a function, or receive a realtime event.
- DatabasesRow and table permissions for users, teams, and roles.
- StorageFile access follows the same users and teams.
- FunctionsRun code on sign-ups, sessions, and team changes.
- RealtimeEvents reach only the users allowed to see them.
- MessagingUsers and teams double as email, SMS, and push targets.
- SitesServer-side sign-in with secure, HTTP-only session cookies.
Security_
Hardened by default, on every plan_
Passwords are hashed with Argon2, and the policies that stop account takeovers are built in. Turn them on from the Console. No plan upgrade required.

One platform_
Auth0 sells sign-in. Appwrite ships the whole platform behind it._
Appwrite Auth is one of ten products in the same open-source platform, so users, data, files, functions, and hosting share one Console and one bill.
- 10
- Appwrite products in one project
- 9
- Not offered by Auth0
Open source_
Own your identity layer_
Auth0 is closed source, and even Private Cloud runs on Okta's terms. Appwrite Auth is open source, so it runs on Appwrite Cloud or on your own servers with the same APIs.

Appwrite vs Auth0_
The sign-in your users expect, at a fraction of the price_
Sign-in methods line up closely. The differences are price, openness, and everything identity connects to.

Migration_
Leave without a single password reset_
- 01ExportRequest a password hash export from Auth0. Hashes use bcrypt.
- 02ImportCreate users with the Users API and their existing bcrypt hashes.
- 03UpgradeEach password is rehashed with Argon2 on the next successful sign-in.
- 04Cut overOptionally keep Auth0 as an OAuth provider in Appwrite during the switch.
// Users exported from Auth0 keep their bcrypt hashes for (const user of auth0Export) { await users.createBcryptUser({ userId: ID.unique(), email: user.email, password: user.passwordHash, // $2b$10$... }) } // First sign-in upgrades each hash to Argon2
Fair play_
When Auth0 might still fit_
Auth0 is a mature identity platform. It may justify the higher price if your requirements look like this.
- 01
You sell to enterprises that require SAML connections, SCIM provisioning, and self-service SSO setup.
- 02
You need adaptive, risk-based MFA and advanced attack protection backed by an SLA.
- 03
You want a hosted Universal Login page and Actions to customize every step of the flow.
- 04
Fine-grained authorization across many services is a core requirement.
Why developers choose Appwrite over Auth0_
For most consumer and SaaS apps, yes. Appwrite Auth covers the sign-in methods and security policies users expect, includes 3x more free monthly active users, costs a fraction of Auth0 as you grow, and is open source. It also comes with a full backend, so the same users and teams secure your data, files, and functions.
