Requirements

What you need to run Uptimer.

Software

Docker 19.03+ (or any OCI runtime). The image is multi-arch — amd64 and arm64.
A database — SQLite needs nothing extra; PostgreSQL is recommended for production. See Choosing a database.

Uptimer is a single static Go binary — no runtime, no build step, and you don’t need Go installed. Prefer not to run Docker? Copy the binary straight out of the image and run it:

docker create --name tmp ghcr.io/myuptime-info/uptimer:1.3.0
docker cp tmp:/app/uptimer ./uptimer && docker rm tmp
./uptimer dev

Hardware

Uptimer is light. Sizing depends on which role you run:

Role	CPU	Memory	Notes
Worker (prober)	1 vCPU	128–256 MB	Scales with number of checks.
Server + SQLite	1 vCPU	256–512 MB	Fine for a single-node install.
Server + PostgreSQL	1–2 vCPU	512 MB+	Recommended for teams / history.

Network

The web UI and REST API share port 2517 (the API is served under /api).
Remote workers connect to the server over gRPC on the port set by grpc.port (UPTIMER__GRPC__PORT) — the reference deployments use 50051. It’s an internal channel; terminate TLS at your reverse proxy when workers run on other hosts.
Outbound access from wherever checks run to whatever you monitor.
