Stack consolidation

Replace five vendors with one.

Each of these tools costs $100–$500/mo and requires its own SDK, webhook, and monitoring. Bastionary does all of it.

SaaS use cases

What you can build with it.

B2B SaaS

Multi-tenant organizations

Each customer gets their own tenant with isolated data, their own SSO config, their own role hierarchy, and their own admin portal. You manage one Bastionary instance.

B2C SaaS

Consumer apps at scale

Social login, magic links, passkeys, risk-based MFA, and breach detection — all configured in minutes. Handle 100K MAU without scaling your auth infrastructure.

Desktop software

Licensed software products

Generate license keys tied to machine IDs. Offline validation via cryptographic signatures. Seat-limited licenses, floating seats, trial → paid conversion.

Platform / API

API-first products

M2M (machine-to-machine) auth with client credentials flow. API keys with scoped permissions. Rate limiting and usage metering per client.

Multi-product companies

One Bastionary instance. Every product you ship.

If you're building multiple SaaS products (like TorqScan + VoicePilot), one Bastionary instance handles auth for all of them. Users can be shared across products or isolated per product. Single sign-on across your entire suite, zero extra infrastructure cost.

Shared identity
One login, access to all your products
Per-product billing
Separate subscriptions, unified user record
Managed login pages
