SynCloud

A self-hosted cloud platform that turns a handful of Linux servers into something between Heroku and AWS: deploy containers, managed databases and Git apps across a fleet of machines from one dashboard, with no Kubernetes or etcd to operate.

Apps from a container image or a Git repository with HTTPS addresses, custom domains, rolling deploys, rollbacks and pre-release migrations; managed PostgreSQL and Valkey (Redis) with replicas, automatic failover, autoscaling, backups and point-in-time restore; a private WireGuard network between nodes with security groups and a managed host firewall; built-in metrics, logs, alerts and traffic insights; teams with IAM users, groups, roles and audited policies; a synctl command-line client and a browser terminal.

One binary per role. A controller (dashboard, API, scheduler, SQLite state with encrypted S3 backups, Traefik ingress, image registry, BuildKit, VictoriaMetrics and VictoriaLogs) and agents on every node that dial out over mutually authenticated gRPC. The control plane is split into focused Go packages — scheduler, autoscaler, certificates, firewall, IAM, backups, builds, Git server and provider connectors — with Protobuf contracts generated through buf. The dashboard is a React single-page app (TanStack Router and Query, ECharts, xterm.js).
