Tremum

A sync and storage engine for local-first applications.

Tremum is a single-binary engine that keeps application data in sync across clients and stores it durably on disk. It exposes one HTTP interface for reads, writes, and a live change stream — no external database, no background services to coordinate.

Data is organized into namespaces. Each namespace is an independent keyspace with its own change log, so unrelated apps can share one engine without stepping on each other.

#Installation

Tremum ships as one static binary. Place it on your host and start it:

# download and start
$ curl -sSL get.lt.stanislav.net/install | sh
$ tremum serve --data /var/lib/tremum
→ listening on :4600 · api ready · sync ready
By default the engine binds to 127.0.0.1:4600. Put it behind your own reverse proxy to expose it over TLS.

#Quickstart

# create a namespace
$ tremum ns create notes

# write a record
$ curl -X PUT :4600/v1/notes/today \
    -d '{"body":"hello"}'

# read it back
$ curl :4600/v1/notes/today
{"body":"hello","rev":1}

#Configuration

Configure with flags, environment variables, or a small YAML file. Flags take precedence.

# tremum.yaml
data:    /var/lib/tremum
listen:  127.0.0.1:4600
log:     info
retention:
  snapshots: 24

#API reference

Every route lives under /v1/<namespace>. Requests without a valid token return 401.
