Your whole SaaS backend.
One SDK.
BuildBase provides authentication, billing, email, user management, and more - so your team ships product, not platform code.
What BuildBase does
BuildBase provides the complete backend infrastructure for SaaS products - auth, billing, email, user management, and workflow automation - ready on day one.
“Launching a SaaS product should mean choosing which features to turn on - not which infrastructure to build.”
- BuildBase Team
The problem
Every SaaS product needs authentication, billing, email, user management, permissions, and webhooks. Every team builds them differently.
60-70% of engineering time goes to platform plumbing instead of product. Features that should take days take months. The infrastructure becomes a maintenance burden for years.
The solution
BuildBase is the complete SaaS backend. Authentication, billing, email campaigns, workflow automation, user management, feature flags - all included.
Integrate with the React SDK or REST APIs. Configure features from the admin dashboard. Ship on day one.
Replaces multiple services
One platform instead of 13 separate services with different APIs, billing cycles, and support channels. Designed to work together.
- Auth0 / Clerk / Kinde - Authentication
- Chargebee / Outseta / Memberstack - Subscription billing
- Mailchimp / Loops / Constant Contact - Email campaigns
- Zapier / Make / n8n - Workflow automation
- LaunchDarkly / Flagsmith / Unleash - Feature flags
- OneSignal - Web push
- Custom RBAC code - Role-based permissions
- Lago / Orb / OpenMeter - Credit and usage metering
- Typeform / Tally / Jotform - Forms
- Svix / Hookdeck / Convoy - Webhook delivery
- Bitly / Dub - Short links
- Custom S3 upload code - Image uploads
- WordPress / Ghost - Blog and site content
