Deep Dive: Switching from Datadog to OneUptime
Trade-offs, installation & data architecture
What you trade away
It covers many adjacent jobs, but its self-hosted stack is far heavier to run and its integration depth and polish trail Datadog's mature managed platform.
How to deploy OneUptime
Hosted signup, or the release-branch Docker Compose stack; Helm is the production path
What it takes to run
The recommended self-hosted footprint is large and production requires secrets, TLS, backups, database care, and frequent upgrades rather than a single lightweight monitor.
Where your data lives
Self-hosted telemetry is stored in ClickHouse, application state and configuration in PostgreSQL, and cache, queues, and sessions in Redis.
Why fork OneUptime instead of vibe-coding a Datadog clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Datadog, collect a bounded set of host metrics and logs into a self-hosted dashboard. The hard boundary is huge integration catalog, global ingestion, correlation, retention, security, and support, plus independent infrastructure and reliable alerting.
