Your backend, already an app

Most backends stop at the API — then you build a second codebase just to use your own data. Baasix ships a drag-and-drop App Builder, so admin panels, dashboards, and internal tools are composed from blocks right on top of your collections. No second codebase.

  • 27 data-bound block types

    Tables, wizard forms, kanban, calendars, charts, maps, reports, tabs, modals — each bound straight to your collections.

  • In-place WYSIWYG editing

    The builder and the finished app are the same components. Toggle “Editing”, arrange blocks on a 12-column grid, done.

  • Governed by your permissions

    Every block rides the RBAC and row-level rules you already defined. No separate access model to maintain.

  • Public pages included

    Publish forms and dashboards to anonymous visitors — no login required, with optional human-check.

The Honest Truth

Why Not Free?Almost Free!

We could have made the Admin UI completely free. But here's a little secret about "free" software in 2025... it often doesn't end well. Let us explain why $9.99/year is actually the most honest deal you'll find.

Less than a coffee per month

At $0.83/month (yearly plan), you're paying less than that fancy latte you'll forget about in 10 minutes. But Baasix? It'll remember your schemas forever! ☕

No "Surprise! We're expensive now"

We've all seen it: free tool gets popular → venture capital arrives → suddenly it costs $99/month. We're staying indie and keeping prices human-friendly. 🛡️

Maintainers gotta eat too

Open source maintainers burning out is the #1 project killer. Your tiny contribution keeps us caffeinated, motivated, and shipping features instead of searching for "real jobs". 💪

Sustainable > Free-until-we-quit

Many free tools are one maintainer burnout away from becoming abandonware. We'd rather charge a coffee and stick around for decades than go free and ghost you. 👻

Our Promise

Your small contribution = Long-term development, regular updates, and a tool that won't suddenly disappear or become unaffordable.

P.S. If $9.99/year is genuinely too much for you, reach out to us. We've got special pricing for students, indie hackers bootstrapping their dreams, and developers from regions where this amount means more. We're here to help, not to gatekeep.

Frequently Asked Questions

Everything you need to know about Baasix

Why is the pricing so affordable?

We believe in sustainable, fair pricing. Our goal isn't to maximize profits—it's to keep development going and maintain the codebase for the community.

We're already profitable through our enterprise client projects where we use Baasix extensively. The license fees help us dedicate time to open-source development, bug fixes, security updates, and new features that benefit everyone.

Think of it as supporting sustainable open-source development rather than paying for software access.
