Cell
A source-available execution core for untrusted code and tool workloads.
View Cell →THE AGE OF EPHEMERALITY
Infrastructure that knows when to leave.
Ephem0ra is building a family of products around one principle: temporary by default, controlled by design and verifiable by evidence.

NOT ONE PRODUCT
A new category
needs room to grow.
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
Your codebase,
read as a city.
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
Many forms.
One principle.
Enterprise
Governance and controlled deployment around the same execution principle.
View Enterprise →Skyline
A local reader that raises any folder as a 3D city and marks risky files with red beacons. No preview exists to open.

More products are in work than this page names. They get a name when they exist — not before.
Talk to us →THE DESIGN RULE
Form. Hold. Prove. Dissolve.
Anything we build next has to make temporary work safer, clearer or more accountable, and leave behind only what matters.
FORMcreate only what the task needs
HOLDkeep the boundary readable
PROVEmake the result verifiable
DISSOLVEremove the unnecessary remainder
THE VISION
Temporary is not smaller.
It is more intentional.
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
The Age of Ephemerality
is only beginning.
If you have a workload that should exist only for the time it needs, we want to hear about it.
