Everything you need to run a rental business

Product Catalogue

Unlimited products with categories, images, specs, pricing tiers, serial tracking, and accessory relationships.

Real-time Availability

Accurate availability engine with calendar views, conflict detection, prep buffers, and overbooking controls.

Quotes & Rentals

Section 04 — Principles

The Signals Manifesto

Four principles we build by. The full manifesto goes deeper.

01

The Framework is Free Forever

AGPL v3-licensed and permanently free. No open core catch.

02

One Version for Everyone

One Signals Framework for every rental business — from a sole trader to a national operation.

03

Built for Rental, Not Adapted for It

Purpose-built for equipment rental. Availability, kit prep, sub-hire — these are the foundation, not afterthoughts.

04

Self-Host Without Compromise

Run Signals on your own server with documentation and upgrade paths maintained as first-class experiences.

Section 05 — Community

Signals is built in the open. Contribute code, report issues, or just say hi.
