Cloudflare stack for micro‑SaaS

Cloudflare’s pitch for small software businesses is getting simple enough to fit in a tweet: Workers for code, D1 for SQL, R2 for files. (developers.cloudflare.com 1) (developers.cloudflare.com 2) (developers.cloudflare.com 3) That is the stack developer Pradeep Mishra highlighted for a micro-SaaS: Cloudflare Workers on the backend, D1 for the database, R2 for object storage, plus PostHog, Sentry and Stripe. (posthog.com) (docs.sentry.io) (docs.stripe.com) Workers is Cloudflare’s serverless runtime, which runs JavaScript or TypeScript on Cloudflare’s network instead of on a rented server you manage yourself. Cloudflare says the free tier includes 100,000 requests per day, while the paid plan starts at $5 a month. (developers.cloudflare.com) D1 is Cloudflare’s managed SQL database with SQLite semantics, designed to be called directly from Workers and sized around smaller 10 gigabyte databases. Cloudflare says D1 includes built-in disaster recovery and point-in-time restore within the last 30 days. (developers.cloudflare.com) R2 handles the files a software product accumulates, like uploads, exports and generated assets. Cloudflare prices standard storage at $0.015 per gigabyte-month and says egress to the internet is free. (developers.cloudflare.com) The rest of the stack fills in the business plumbing. PostHog documents a Cloudflare Workers library for analytics and feature flags, Sentry supports Workers and Pages for error tracking, and Stripe’s subscription docs center webhook events for billing state changes. (posthog.com) (docs.sentry.io) (docs.stripe.com) Cloudflare also has a bridge for teams that are not ready to move their database. Hyperdrive connects Workers to existing PostgreSQL or MySQL databases and adds global connection pooling and query caching. (developers.cloudflare.com) That makes the stack less a single product than a low-ops template: edge compute, a small SQL store, object storage, analytics, error monitoring and payments. For a hobby app or early paid product, it is close to a complete software business without a traditional server fleet. (developers.cloudflare.com 1) (developers.cloudflare.com 2) (developers.cloudflare.com 3) The tradeoff is in the shape of the app. D1 is built around SQLite and smaller databases, and Stripe subscriptions still depend on webhook handling, so the setup fits lean products better than large, state-heavy systems. (developers.cloudflare.com) (docs.stripe.com) For developers trying to ship a paid side project with one cloud vendor and a short bill, that is the appeal Pradeep Mishra was pointing at: enough infrastructure to launch, without much infrastructure to run.
