Ship auth in a day.
Not a sprint.
Every startup wastes 2–3 weeks on login screens, OAuth flows, and JWT plumbing. That's runway burned on infrastructure Auth0 will charge you for anyway. Bastionary ends that.
14-day trial. No credit card. Self-hosted option is free forever.
Every startup gets stuck in auth hell.
2–3 weeks of sprint burned on login
Sessions, JWTs, OAuth flows, password reset, email verification, rate limiting, MFA, audit logs. Every startup builds this. All of it exists already.
Auth0 bills you like a public company
Auth0's pricing is tiered and grows materially as your user base or enterprise feature needs expand. Costs scale in ways that become a significant factor well before you hit meaningful scale. Their pricing model punishes growth at the exact moment you can least afford it.
Five vendors before you've shipped v1
Auth0 for identity. Stripe for billing. LaunchDarkly for flags. Keygen for licensing. LemonSqueezy for checkout. Every integration is a new failure point.
Everything you need. One afternoon to integrate.
Auth in one afternoon
Copy 20 lines of code, call three API endpoints, you're done. Login, signup, sessions, MFA, and social login — all working before lunch.
Free until you need to pay
Self-host on a $6/mo VPS indefinitely. Cloud Starter is $29/mo — less than one Auth0 user tier. You scale your pricing when you scale your revenue.
Billing + licensing built in
Drop Stripe's SDK, Keygen, and LaunchDarkly. Bastionary handles subscriptions, license keys, feature flags, and usage metering. One SDK, one dashboard.
Everything a Series A startup has. For $29/mo.
Complete authentication stack
Email/password, magic links, passkeys, Google/GitHub/10 social providers, TOTP MFA, SMS MFA, risk engine, impossible-travel detection, HIBP breach check.
Billing and subscriptions
Stripe integration, subscription lifecycle, dunning, seat billing, metered usage, invoices. Wire it to your pricing in hours.
Feature flags and licensing
Boolean flags, rollout percentages, tier-based access (pro/enterprise). License key generation with expiry, machine limits, and offline validation.
Audit logs and compliance hooks
Every auth event logged with IP, device, timestamp. SHA-256 chained for tamper evidence. GDPR delete endpoint. You're audit-ready from day one.
Webhooks and real-time events
Push any auth event to your backend. Login, logout, password change, new device, trial expiry — your system stays in sync without polling.
Stop building auth. Start building your product.
