ReadyKit

What it does

ReadyKit is an open-source (MIT) SaaS starter kit built with Python (Flask 3), Vue 3, PostgreSQL, Redis, and Celery. It provides multi-tenant workspaces with automatic data isolation, subscription billing via Stripe or Chargebee, and enterprise-grade authentication (OAuth, TOTP MFA, Passkeys/WebAuthn). The kit includes prebuilt dashboard screens, audit logs, and one-command Docker deployment to platforms like Fly.io and Railway.

Who it is for

ReadyKit targets solo developers, small teams, and startups who want to launch a SaaS product quickly without building the common infrastructure from scratch. It is especially suited for Python developers who prefer self-hosted solutions over third-party services like Auth0 or Clerk. The kit supports both solo users (who get an instant workspace) and teams (with workspace switcher, roles, invites, and audit logs).

Why it matters

Building a SaaS product involves repetitive plumbing: user authentication, multi-tenancy, billing, and deployment. ReadyKit eliminates this boilerplate, allowing developers to focus on business logic. The MIT license gives full commercial freedom, and the self-hosted approach avoids vendor lock-in and per-MAU pricing. The kit claims to handle 2.8B+ rows and enable 392% faster iteration, though these metrics are not independently verified.

Launch signal

ReadyKit was launched on Hacker News as a Show HN post titled "Superfast SaaS Starter with Multi-Tenant Workspaces." The website offers a live demo and a GitHub repository for immediate access. The project is in pre-seed stage, created by developer level09.

Brand and naming

The name "ReadyKit" combines "ready" (implying immediate usability) with "kit" (a collection of tools). It is short, memorable, and clearly communicates the product's purpose as a starter kit. The tagline "Superfast SaaS Starter" reinforces speed and ease of use. The brand positions itself as a developer-friendly, open-source alternative to paid SaaS boilerplates.
