Applications

Software you can run, not just import

The kits are libraries you embed. These are whole applications built on them — a CRM, an email API, and a teammate that remembers. Each one carries the posture the family gives it: isolation Postgres enforces, money that is exact, auth that holds. Take the open core and host it yourself, or hand us the operations.

QuxKit CRM

A full CRM & HR platform — leads to invoices, projects to tickets — built on identity-kit, tenant-kit and billing-kit. Run it yourself, or let us host it with native mobile.

QuxMail

A transactional email API and control plane, composed from four kits. Point your existing SDK at it — domains, sends, events, suppression, webhooks, metering and caps, done for you.

AI Member Cloud

The member that remembers, for a team. Organisations, roles, invitations, API keys and MFA over the open core — with tenant isolation Postgres enforces, so a query that forgets whose memory it is reading returns nothing at all.

Explore AI Member Cloud

Two ways in, always. Every application here has an open core you can self-host from the kits it is built on; the managed versions are ours to run, on the same code. If you would rather start from an empty repo than a finished product, that is Solutions — App-Kit and UI-Kit install into your own codebase and stay there.
