Features

The platform we wish we had ten years ago.

Everything you need to ship a production app, without writing yaml or babysitting clusters.

Auto-build with Nixpacks

Push code, Dockfly figures out the rest. Nixpacks inspects your repo, picks the right toolchain, installs dependencies, and produces a small OCI image — no Dockerfile required.

  • Auto-detects 30+ languages and frameworks.
  • Reuses caches between builds for fast iteration.
  • Bring a Dockerfile if you need full control.

Real-time logs

Stream stdout, stderr, and access logs from every container live in your browser. Filter, search, and share permalinks to a specific moment in time.

  • Live tail via Server-Sent Events.
  • Filter by service, deploy, level.
  • Up to 90-day retention on paid plans.

Multi-service projects

Group web, worker, cron, and database services under one project. Service URLs and credentials are wired via environment variables so your code can stay simple.

  • Web, worker, and cron services in one project.
  • Connection strings injected as env vars.
  • Private networking, public TLS endpoints.

Custom domains + auto-SSL

Bring your own domain, or use a free dockfly.app subdomain. TLS certificates are issued, renewed, and rotated for you — DNS and HTTP-01 challenges handled.

  • Wildcard certs via DNS-01 challenge.
  • Automatic Let's Encrypt renewal.
  • Force-HTTPS and HSTS opt-in.

Environment variables (encrypted)

Manage secrets at the project or service level. Values are encrypted at rest with envelope encryption and never appear in build logs or audit exports.

  • Per-environment overrides (preview / staging / production).
  • Secret values never logged or shown after creation.
  • Sealed import / export for team rotation.
bash
 1# Set secrets from your terminal
 2$ dockfly env set DATABASE_URL=postgres://… --service api
 3✓ Set 1 variable (encrypted at rest)
 4
 5# Or copy from .env
 6$ dockfly env import .env --service api
 7✓ Imported 18 variables

Metrics & monitoring

Every service ships with a Prometheus-compatible metrics endpoint and a built-in dashboard. CPU, memory, latency, and error rate are charted automatically.

  • 15-second resolution metrics, retained 30 days.
  • p50 / p95 / p99 latency per service.
  • Email, Slack, or webhook alerts.

Auto-scaling

Scale horizontally with one click, or let Dockfly do it for you based on CPU and request volume. Zero-downtime rollouts handle the rest.

  • Manual replica count or CPU-based autoscale.
  • Rolling deploys with health-check gating.
  • Per-service min/max bounds.
yaml
 1scale:
 2  min: 1
 3  max: 8
 4  metric: cpu
 5  target: 70
 6  cooldown: 60s

GitHub integration

Install the Dockfly GitHub App once. Branches deploy automatically, pull requests get isolated preview URLs, and merging cleans them up.

  • Auto-deploy on push to main, branches, or tags.
  • Pull request preview environments.
  • Status checks back to GitHub.
