European platform-as-a-service for deploying and running containerised applications

scalingo.com ↗

Scalingo runs a steady runtime-version maintenance cadence with a notable platform swap memory policy change.

◆Current state
Scalingo is a European PaaS (Heroku alternative) that keeps its buildpack ecosystem current across Ruby, Node.js, Go, Java, Python, and PHP. The release cadence is almost entirely version bumps: new runtimes and tooling versions land within days of upstream releases. The one platform-level change visible across recent entries is a swap memory policy shift—new applications no longer get swap memory as of September 2026, and existing apps will have swap reduced to 25% of container memory on their next restart. That's a behavioral change that affects memory-intensive applications.
◆Where it's heading
Scalingo is in operational steady-state: a PaaS maintaining its runtime catalog and platform stability rather than expanding its product surface. No new features or architectural moves are visible in recent entries. The swap memory change suggests resource efficiency work at the infrastructure level, likely tied to capacity management or performance improvements on shared infrastructure. The support for multiple Python package managers (uv, Poetry, Pipenv) in parallel suggests responsiveness to the Python ecosystem's tooling fragmentation.
◆Prediction
Scalingo will continue rapid runtime version tracking as upstream releases land. Any platform-level changes will be telegraphed by operational announcements like the swap memory notice. A directional move—new regions, GPU support, serverless containers—would need to appear in a product announcement rather than a buildpack entry.
