Cell
A source-available execution core for untrusted code and tool workloads.
View Cell →THE AGE OF EPHEMERALITY
Ephem0ra is building a family of products around one principle: temporary by default, controlled by design and verifiable by evidence.
NOT ONE PRODUCT
Cell is the execution layer that ships today. Around it sits Enterprise, the governance layer, still in design. Skyline is a private build that reads one folder on your machine. The family does not end there: more products are in development than this page can name.
THE THIRD PRODUCT
Skyline opens a folder on your own machine and raises it as a city in daylight: folders become districts, files become buildings, and the tangled ones grow tall. Red beacons mark security findings, red rings mark circular imports, yellow arcs mark copy-paste clones. The source never leaves the machine.
Local analysis is bounded at 3,000 files, 40 MB and 2 MB per file. node_modules, .git and build output are skipped, and what a folder leaves out stays on screen as “+N more files” instead of vanishing.

THE CONSTELLATION
A source-available execution core for untrusted code and tool workloads.
View Cell →Governance and controlled deployment around the same execution principle.
View Enterprise →A local reader that raises any folder as a 3D city and marks risky files with red beacons. No preview exists to open.
Talk to us →More products are in work than this page names. They get a name when they exist — not before.
Talk to us →THE DESIGN RULE
Anything we build next has to make temporary work safer, clearer or more accountable, and leave behind only what matters.
THE VISION
The Age of Ephemerality is a shift from permanent access to purposeful presence: infrastructure appears when needed, does its job and leaves a clear record.

THE OPEN QUESTION
If you have a workload that should exist only for the time it needs, we want to hear about it.
