The story

Kamra means room. The door is open on purpose.

Why we chose the name, why we built on Frappe, and why Kamra is open source and free forever.

Why the name Kamra

A property management system exists to do one thing above all others: manage rooms. So we named it after the word for room, in the language of the place it is built.

In Hindi and Urdu, kamra (कमरा) means room. It is one of those everyday words that travelled a very long way to get there. It shares its roots with the Latin camera, a vaulted chamber or room, which is also where the word for the picture-taking device comes from. In Italian, camera still simply means room today, as in camera d'albergo, a hotel room. And in Maltese, a European language spoken in the Mediterranean, the very same word survives as kamra, room.

Look closely at the logo and you will see a door opening into a letter K. The door is open on purpose. Kamra is open source, open to your data, and open to whichever AI you choose to bring. Nothing about it is locked.

Why we built on Frappe

Kamra is built on the Frappe framework, the same open-source platform that powers ERPNext, one of the world's largest open-source ERPs. That choice was deliberate.

• A mature foundation. Frappe brings real role-based access control, audit trails and multi-tenancy out of the box, the exact things a hotel system cannot cut corners on.
• A real ecosystem. The frappe/payments app, a huge library of integrations, and a large, active developer community mean Kamra is not starting from zero.
• Metadata-driven, and so agent-friendly. Frappe describes its own data model, which makes it a natural fit for AI agents that need to understand and act on your property safely.
• Yours to extend. Standard Python and a documented data model mean any developer can add fields, workflows and whole modules without fighting the platform.

Why open source, and free forever

Kamra is licensed under AGPL-3.0. It is free forever, with no per-room pricing, no per-user seats and no license audits. That is a stance, not a marketing line.

• You own your data. Guest history, rate history and your books live on infrastructure you control. No vendor cloud, no export fee to leave.
• No black boxes. Read every line. Real RBAC, real audit trails, documented REST and MCP surfaces, and an eval suite in CI. Trust because you can verify, not because we asked you to.
• It cannot be taken away. Because the source is yours, no vendor decision can strand your hotel. Fork it if you ever need to.
• The AGPL keeps the ecosystem honest. Anyone offering Kamra as a hosted service must share their improvements back, so the whole community moves forward together.

For hotel owners

You own the software, the server and every byte of your data. Costs do not scale with your room count. Your AI front desk works from day one. And if you ever want managed hosting or AI staff on voice and WhatsApp on top, those are choices, not ransoms.

For IT teams

Standard Python on Frappe, with a React front end. Real RBAC, real audit trails, documented REST and MCP surfaces, and an eval suite in CI. No black boxes. Fork it, extend it, and ship your own modules. That is the point.
