Hey HN, we're building a library of open source SaaS apps for small businesses and personal use. You can browse the apps at https://builder.replay.io, these are free to copy or download and use however you want. Examples:

* https://builder.replay.io/gallery/Sales%20CRM — Sales CRM with pipeline view and deal tracking * https://builder.replay.io/gallery/Issue%20Tracker — Issue tracker with projects and triage view * https://builder.replay.io/gallery/Team%20Wiki - Internal docs with nested pages and customizable tables * https://builder.replay.io/gallery/Invoicerator — Time tracking + invoice generation for freelancers * https://builder.replay.io/gallery/Accounterize - Accounting system for tracking financial transactions * https://builder.replay.io/gallery/Inventory%20Tracker - Inventory management for production facilities

We love building bespoke software with AI, but many businesses have needs for similar tools and we want to strike a middle ground between having to build something from scratch or pay for expensive and immutable off the shelf software.

These apps have comprehensive, passing test suites and are a good place to start for a vibe coding project, but we're also building out the apps (and their test suites) into complete tools ready for immediate use. See more here: https://blog.replay.io/communal-saas-apps

If you're interested in using these you can sign up as an early adopter on any of the app landing pages, and we'll support you to make sure things are working great.
