Platform

Heroku experience.
DigitalOcean primitives.

Isle gives you the developer experience of Heroku on top of real, isolated infrastructure in Europe. No YAML. No Kubernetes to operate. No AWS bill shock.

Real compute, real isolation

Every service runs in its own KVM hypervisor on dedicated Hetzner hardware. No shared tenancy, no noisy neighbours. Choose your instance size — from Sprout (512 MB) to Redwood (32 GB).

  • KVM-isolated virtual machines
  • Sprout → Birch → Oak → Cedar → Sequoia → Redwood tiers
  • Reserved and on-demand billing modes
  • EU-only infrastructure (Germany & Finland)

Managed Postgres & Redis

Provision a production-grade database in 90 seconds. High availability, automatic failover, and continuous WAL backups are included on every paid tier.

  • Postgres 16 with HA and automatic failover
  • Read replicas on Oak tier and above
  • Point-in-time recovery to any second (7-day window)
  • Redis 7.4 with AOF / RDB persistence
  • PgBouncer connection pooler included

Git-driven deploys

Connect your GitHub or GitLab repo. Isle detects your language, runs Cloud Native Buildpacks, and ships on every push to main — or any branch you configure.

  • Auto-detect Node.js, Python, Go, Ruby, Java, PHP
  • Custom build and start commands
  • Preview environments per pull request
  • One-click rollback to any previous deploy
  • Deploy webhooks for CI/CD integration

Private networking by default

Every organisation gets its own VPC at signup. Services discover each other by name over an encrypted internal network — no IPs, no certificates to manage.

  • Isolated VPC per organisation
  • Internal DNS (e.g. http://api, postgres://db)
  • End-to-end encryption on internal traffic
  • Configurable firewall rules per service
  • No egress charges between services

Custom domains & managed TLS

Add your domain, point a CNAME, and Isle takes care of certificate provisioning and renewal. HTTPS from your first deploy.

  • Free TLS certificates via Let's Encrypt
  • Auto-renewal — zero operational overhead
  • CNAME verified in under 60 seconds
  • Wildcard domains supported on Cedar tier
  • HTTP → HTTPS redirect enforced by default

Observability built in

CPU, memory, request rate, p50/p95/p99 latency, and error rate — all on the same screen as your deploys. No external tools required.

  • Per-instance CPU and memory graphs
  • Request rate and latency percentiles
  • Streaming log viewer with full-text search
  • Deploy event markers on metric charts
  • Log export to S3-compatible storage
