Add-ons

Managed services. One command away.

Pick a service, run one CLI command, get connection details injected as config vars. Backups, monitoring, and Grafana are wired in automatically.

PostgreSQL

Relational database from €3/mo

The default for transactional application data. Standard adds async read replicas; Premium adds a sync standby with automatic failover when the primary dies. Scheduled backups from Standard up; restore-and-promote workflow on every tier.

  • Hobby 0/1 — single-node, manual backups
  • Standard 0–4 — production tier with async replicas
  • Premium 1–4 — sync-standby HA, geo-distributed options
  • CLI: watasu pg:psql, watasu pg:follow, watasu pg:backups
watasu addons:create postgresql --app my-app

Valkey

Redis-compatible cache free hobby tier

In-memory data store for caching, sessions, rate limiting, and ephemeral coordination. Speaks the Redis protocol — existing client libraries work unchanged. Auto-failover from Standard, triple-zone HA on Premium.

  • Hobby 0–2 — single-zone, manual backups (Hobby 0 is non-persistent)
  • Standard 0–2 — auto-failover + scheduled backups by default
  • Premium 0–3 — triple-zone HA + scheduled backups
  • CLI: watasu valkey:cli (or redis:cli alias)
watasu addons:create valkey:hobby-1 --app my-app

ClickHouse

Analytical database from €15/mo

For event data, time series, and dashboards over millions or billions of rows. Wide aggregations in seconds. Manual + scheduled backups; multi-shard Premium tiers for serious scale.

  • Starter — non-production exploration
  • Standard — production single-node
  • Premium — multi-shard scale-out
  • CLI: watasu clickhouse:cli
watasu addons:create clickhouse --app my-app

Redpanda

Kafka-compatible streaming from €30/mo

Durable, ordered, replayable event streams. Speaks the Kafka protocol — Kafka clients work unchanged. Built for event sourcing, audit logs, and decoupled service architectures.

  • Hobby — single broker for development
  • Standard — multi-broker for production
  • Premium — high-throughput multi-broker
  • Use any Kafka-compatible client library

Object Storage

S3-compatible bucket from €2/mo

Per-app S3-compatible bucket with scoped credentials. One add-on = one bucket + one access key pair (no IAM gymnastics). Generous env-var compatibility — boto3, aws-sdk-*, rclone, and friends just work. Premium tiers are geo-replicated across three German zones.

  • Hobby 0–1 — 25 GB to 100 GB, single-zone
  • Standard 0–2 — up to 1 TB single-zone
  • Premium 0–2 — up to 4 TB geo-replicated (nbg + fsn + hel)
  • Auto-injected: S3_BUCKET, AWS_*, AWS_ENDPOINT_URL

Logs · Metrics · Traces · Grafana

Observability free hobby tier

Per-app Grafana provisioned the first time you attach an observability add-on. Centralized logs, Prometheus-compatible metrics, OpenTelemetry traces — correlated in one UI with dashboards, Explore, and alerts.

  • Logs hobby — 1 GB/mo ingest
  • Metrics hobby — 1,000 active series
  • Traces hobby — 1 GB/mo ingest
  • Grafana included with any monitoring add-on
