Last verified: 6 Nov 2026 Prices and limits as of November 2026 Found an error? info@watasu.io

Run your apps, workers and managed databases in Germany with Watasu. Get fixed monthly Standard pod prices, normal app bandwidth included, builds at €0.50/hour by running seconds, and no workspace or per-seat fees.

Watasu and Render both run long-lived services, build from Git or a Dockerfile, and offer managed PostgreSQL and a Redis-compatible store. Render offers more regions and an eligible free tier. The main differences for production teams are where their data lives, how traffic is billed and which managed services they can attach.

Who should choose which

What Watasu and Render have in common

• Long-running services. Run web apps, private services and workers. Both platforms support WebSockets, and Render’s paid web services stay online during idle periods.
• Git deploys and previews. Deploy from a connected repository and test changes in a preview. Watasu review apps can provision the add-ons declared in app.json.
• Dockerfile or platform builds. Both platforms build a Dockerfile. Render also offers native runtimes, while Watasu uses Cloud Native Buildpacks.
• Managed Postgres and Valkey. Render offers Postgres and Key Value, which runs Valkey. Watasu offers PostgreSQL and Valkey add-ons.
• Developer tooling. Both offer a CLI, an MCP server, logs and metrics. Render Pro includes unlimited seats for a flat workspace fee. Watasu has no workspace or per-seat fees.

Pricing

Watasu app builds have limits of 16 vCPU and 30 GiB RAM and cost €0.50/hour by actual running seconds, including failed and canceled builds. Queue time and image-only pipeline promotions have no build charge. Before execution, a temporary hold of up to €0.50 funds at most one hour, or a shorter deadline from a smaller available balance; unused funds return after the build stops. Enough available balance for one second is required, with no saved-card requirement or free monthly build allowance. App runtime examples below exclude build charges unless a build row is shown.

Render’s pricing separates the workspace fee, compute and metered features. A workspace costs $0 on Hobby, $25/month on Pro or $499/month on Scale. Those plans include 5 GB, 25 GB and 1 TB of monthly outbound bandwidth respectively, with additional usage at $0.15/GB. They include 500, 1,000 and 5,000 standard build minutes respectively. Additional standard build minutes cost $5 per 1,000.

With Watasu pricing, top up one euro balance from €5. Standard gives each running replica a fixed monthly price for steady workloads. Dynamic bills measured CPU and memory at €20 per average vCPU-month and €10 per average GiB-month, with a monthly ceiling per replica. Normal app bandwidth is included. App builds cost €0.50/hour by running seconds. If the balance runs out, Watasu pauses workloads until you top up.

Key differences

Infrastructure and scaling

On Render, choose a web service, private service, worker or cron job, then assign a compute plan. Paid app services start at $7/month for 0.5 CPU and 512 MB. A cron job runs on a UTC schedule and has a $1 monthly minimum per job. Pro supports horizontal autoscaling. Attaching a persistent disk limits a service to one instance and disables zero-downtime deploys.

On Watasu, a Procfile defines your app’s processes. Use web for public HTTP and WebSockets, worker for queues or schedulers, *-tcp for private TCP and gRPC, *-rtc for real-time media and release for migrations before a new version goes live. Each process has its own pod size, replica count and billing model.

Where your data lives

Render Services, Inc. is a U.S. company. You can host apps and Postgres in Frankfurt. You choose the region when you create a service or database. Render’s static sites use a global CDN, and its sandbox beta runs in Oregon.

The U.S. CLOUD Act can apply even when data is hosted in the EU. Under 18 U.S.C. § 2713, valid U.S. legal process can require a covered provider to disclose data in its possession, custody or control, wherever that data is stored.

Watasu LTD is registered in England and Wales. Watasu hosts apps and add-ons in Germany. Customer workload data, including app images, databases, backups, logs, metrics, traces and object storage, stays in the EU. Watasu sandboxes also run in the EU.

Databases and backend services

Paid Render Postgres starts at $6/month plus $0.30/GB for storage. On Pro workspaces, paid databases have a seven-day point-in-time recovery window. An HA standby requires an eligible Pro or Accelerated database plan. Up to five read replicas are available on qualifying databases. Render bills each standby or read replica separately. Paid Key Value starts at $10/month and offers disk-backed persistence.

Watasu manages PostgreSQL, Valkey, ClickHouse, Qdrant, Redpanda and S3-compatible Object Storage next to your app. PostgreSQL starts at €5/month, with scheduled backups on Standard and above, followers from Standard 1 and synchronous standby on eligible Premium plans. Valkey starts at €1/month, with automatic failover on Premium. Object Storage starts at €2/month with a plan-specific egress allowance.

Real-time, voice and long-running work

Render documents up to 100 minutes for HTTP responses and no fixed WebSocket duration limit. WebSockets can still disconnect during deploys or network interruptions. Render’s public web ingress is HTTP-based. Watasu’s real-time processes get a TURN gateway, a public UDP port and a stable hostname for each replica, so you can run your own WebRTC media server.

AI sandboxes

Render Sandboxes is in public beta. It offers reusable snapshots and TypeScript and Python SDKs in Oregon. For the default 1 CPU and 2 GB size, Render lists $0.12 per active CPU-hour plus $0.038 per hour for memory. Private networking to other Render services and public URLs are currently unavailable in the beta.

Watasu offers EU sandboxes with reusable templates, SSH, file and command APIs, pause and resume, checkpoints and outbound network policies. Runtime is billed per second for requested CPU and memory. A 2 vCPU, 1 GiB sandbox costs about €0.16 per runtime hour. The free Basic team plan allows 20 concurrent sandboxes, and Pro is €150/month for up to 100. Runtime and retained storage are separate from the team plan.

Developer workflow

Render groups services into projects and environments. A render.yaml Blueprint can declare services, databases and environment groups. Pro includes full-stack preview environments, and Render offers a CLI, REST API, MCP server and Terraform provider.

On Watasu, an app holds its processes and attached services. Configure review apps with app.json and use pipelines to promote the same tested image from staging to production. Access is scoped per app or pipeline. Attach Logs, Metrics or Traces for a Grafana workspace, and use the MCP server to inspect apps or make changes within your connection’s permissions.

Migrate from Render to Watasu

Start by mapping your Render services to Watasu processes and checking the environment variables, persistent files and databases each one needs.

1. Create the app and connect GitHub. Create an app in the dashboard or CLI. Connect the repository for automatic deploys, or push to the app remote with git push watasu main.
2. Define your processes. Put a Procfile in the repository root. Map Render web services to web, background workers to worker and private TCP services to a *-tcp process. For scheduled work, run a scheduler in a worker. Watasu uses your root Dockerfile if one is present.

   web: npm run start
   worker: node worker.js
   release: npx prisma migrate deploy

3. Move databases and files. Attach the add-ons you need, for example watasu addons:create postgresql --app my-app. Export Render Postgres from the Recovery page where available, or use pg_dump with the external database URL. Follow the Watasu restore workflow and validate the restored database before switching traffic. Copy persistent files to Object Storage if your app can use S3-compatible storage.
4. Recreate configuration. Copy application settings from the Render dashboard and recreate secrets from your secret store. Use the connection variables injected by your Watasu add-ons.
5. Test before pointing DNS at Watasu. Confirm the web service, workers, data and scheduled jobs behave as expected. Add your custom domain, update DNS and verify managed TLS.
6. Set up previews and promotion. Enable review apps for pull requests and connect staging and production in a pipeline to promote tested builds without rebuilding.
