The Recipe Manifesto

Why Solo & Indie?

The principles we uphold to build software tools that last decades, not quarters.

speed

Zero Bloat, Micro Latency

No endless meeting overhead or enterprise features you didn't ask for. We measure UI render passes in single-digit milliseconds and ship binary sizes under 15MB.

check_circleSub-60ms cold boot guarantee
lock

Absolute Privacy by Default

Your keystrokes and workflow logs never touch surveillance servers. Database keys are preserved on local hardware or synced end-to-end via your own Apple iCloud containers.

check_circleNo 3rd-party trackers or telemetry
all_inclusive

Pay Once, Own Forever

We hate vampire SaaS subscriptions as much as you do. Apps are offered with clean perpetual lifetime licenses and crystal-clear self-hosted sync options.
