Your SaaS, production-ready from day one
Warpkit gives you OTP auth, Stripe billing, and a per-user SQLite database so you can focus on building your product: not the plumbing.
Not a demo , this stack runs real, live products
80% of SaaS projects fail because founders run out of time before launch
Auth, billing, email, database: you spend weeks on plumbing before writing a single line of product logic.
Weeks building auth & billing
Burned out before launch
Project abandoned
Stop reinventing the wheel
Without Warpkit
- Spend days wiring auth from scratch
- Copy-paste Stripe webhook code from docs
- Debug concurrent SQLite write errors
- Ship week 6 instead of day 1
With Warpkit
- OTP auth ready in 5 minutes
- Stripe billing + webhooks pre-wired
- Per-user SQLite with write locks built in
- Deploy on day 1, build features on day 2
Everything you need to ship
Stop rebuilding auth and billing for every project. Start with a solid foundation and build the thing only you can build.
OTP Auth + Multi-session
Passwordless login via email OTP. Users stay signed in across devices with multi-session support built in.
Stripe billing, done right
Checkout, customer portal, and webhook handling. One boolean: hasAccess: tells you everything you need.
Per-user SQLite
Every user gets their own isolated SQLite database. No shared schema, no cross-user leaks, no complex row-level security.
Background jobs
SQLite-backed queue with retries, dead-letter handling, and graceful shutdown. Survives server restarts.
Admin panel
User management, impersonation, and access control at /dashboard/admin, guarded and audit-logged.
Typed error handling
Every server function returns Result<T>, not a thrown exception. Errors are values you check, not surprises you catch.
TanStack Start
Full-stack React with server functions, file-based routing, and TanStack Query. The modern way to build.
GDPR export + deletion
Durable, crash-safe account deletion and full data export, built in, not bolted on later.
Blog + MDX
Content collections with MDX support. Write posts in Markdown, get a fast statically-rendered blog.
29+ hours of things that are easy to get wrong
Not just wiring , the parts that take real hours to get right: race conditions, replay safety, crash-safe state machines.
Passwordless auth
OTP + magic link, rate limiting, disposable-email gating
Stripe billing
Checkout, portal, webhook replay-safety on redelivery
Per-user SQLite
Write-lock serialization, migrations, no SQLITE_BUSY races
Background jobs
Retries, dead-letter queue, graceful shutdown, stale-job recovery
Admin panel
Impersonation guard, audit trail, promotion flow
GDPR deletion + export
Durable multi-step state machine, crash-safe resume
Typed error handling
Result<T> across every server function, nothing to try/catch
Security headers + rate limiting
CSP, X-Frame-Options, IP-keyed limiter on every auth endpoint
Built for how you actually ship in 2026
A checked-in CLAUDE.md and six real Claude Code skills, not a marketing claim. Your AI assistant reads actual conventions on day one, not a wiki it ignores. Works just as well with Cursor, Windsurf, and GitHub Copilot.

Built by an engineer who ships production code
I'm Daniel, known online as bitclaw. 17 years building production systems for U.S. companies, remote. Currently leading a team of engineers taking a monolith to microservices. Warpkit is the stack I actually reach for , it's what runs RunMist and WeatherDestination too , backed by the same CI discipline I'd want on a team I'm responsible for: hundreds of tests, boot-smoke checks, and convention audits, not just a README.
