A data layer with no center.
Yes, it's peer-to-peer. No, not that kind.
Realtime streaming that forgets everything on purpose. Storage that's a switch, not a default. Runs on a box that costs less than your coffee habit.
No servers own your data.
Low volume. Only when something real ships. Unsubscribe any time.
The pitch, fast
The usual "realtime" stack
- Writes everything to a database you never asked for
- Lives on servers you don't control
- Bills you like you'll never leave
Cortex Mesh
- Streams first — storage is a per-node switch, off unless you flip it
- Runs on $6/mo boxes, yours or ours, no central server to own the data
- Trust is a signing key you hold, not an account you rent
Cheap enough to be your own infrastructure. Sturdy enough to sell as someone else's.
The pieces
Pick one. Each does one job, has strong opinions about it, and isn't shy about what it doesn't do yet.
Realtime pub/sub
Topic streaming over authenticated links. On by default. Never opens a storage handle.
built · off by defaultCRDT shard storage
LWW-maps and OR-sets, hash-ring placement, anti-entropy. Durability you opt into per node.
built · partialSQL-shaped layer
Tables and secondary indexes over the shard store. A Go API today; a real parser later.
builtMesh transport & trust
Mutual TLS 1.3 between peers that both carry a certificate signed by your mesh root.
builtmeshctl
Stand up a mesh, mint identities, issue certs, read a node's real status. One binary.
soonThe capacity brain
One server that watches demand, predicts need, and assigns roles. Not built yet.
