Our focus

Purpose-built products

Two flagship projects that respect your data while delivering everyday reliability.

PFM

Pulse Finance Manager

SaaS + Self-hosted

A clear view of accounts, spending, and cash flow. Pulse PFM pairs a polished SaaS with a self-hosted edition so you can run finance on your own stack.

  • Consolidated balances and spending insights.
  • API-first with export-friendly data.
  • Self-hosted: keep your data, or plug into the hosted data feed.
  • Hosted data feed saves you from chasing provider credentials and keys.

Data and hosting

Your stack, your choice

Run privately, or lean on our SaaS where it saves time. Either way, ownership stays with you.

Self-hosted, first-class

Deploy Pulse PFM or CalCard on your own infra. Keep control of credentials, storage, and auditability.

Hosted with escape hatches

Use the SaaS for speed, then export anytime. Pulse's hosted data feed keeps integrations alive without chasing provider keys.

Interoperable

Standards and APIs first. CalDAV/CardDAV and JSON APIs keep you free to move and integrate.

Open by design

CalCard is donation-ware

Support the project if it saves you time, but the code stays open for inspection and improvements.

Transparent code

Review, fork, and self-host without friction. Contributions and issue reports are welcome.

Fair sustainability

Donations fuel maintenance and new protocol work while keeping the project accessible to everyone.
