PreviewDrop vs Netlify
Preview URLs for the backend half of your stack
Netlify's deploy previews are a great experience for static sites and JAMstack frontends. PreviewDrop covers what Netlify doesn't: Django, Rails, Laravel, FastAPI, Spring Boot, and anything else that runs in Docker.
TL;DR
Netlify's deploy previews are excellent — for Next.js, Gatsby, Astro, and static sites. If your repo is a Rails monolith, a Django API, a Laravel app, or a Go binary, Netlify simply doesn't run it. PreviewDrop is designed for full-container backend stacks that run as persistent processes.
Feature-by-feature
| Feature | PreviewDrop | Netlify |
|---|---|---|
| Target stack | Any Docker-compatible app | Static sites & JAMstack frontends |
| Django / Rails / Laravel support | First-class | Not supported natively |
| Long-running processes | Run in the container | Functions only (10s / 26s limits) |
| WebSocket / SSE support | Native | Not supported on Functions |
| Database migrations | Run at container start | No persistent process to run them |
| Celery / Sidekiq / queue workers | Second project, same repo | Requires separate service |
| Pricing model | Flat $0 / $19 / $79 / $149 | Per-seat + bandwidth-based |
| Preview URLs on every PR | ||
| PR comments | Built-in | Built-in |
| Custom Dockerfile | Any Dockerfile | Not supported |

What's actually different
Serverless functions vs containers
Netlify's backend model is serverless Functions (Node/Deno/Go) with 10-second sync / 26-second background limits. Django, Rails, and Laravel apps with long-running requests, migrations, and background workers don't fit that shape. PreviewDrop runs the same container you'd run in prod.
Stack compatibility
Netlify previews work beautifully for any framework that compiles to static HTML + a thin API layer. The moment your backend has a Dockerfile, Celery workers, custom middleware, or a framework not on Netlify's supported list, you're outside their model. PreviewDrop's rule is simpler: if it has a Dockerfile, it works.
Predictable cost
Netlify's bill includes bandwidth and function invocations that scale with traffic. PreviewDrop's bill is flat — $19, $79, or $149 — and doesn't move when you push more branches or get a spike of QA traffic on a preview.
When Netlify is the better fit
Pure JAMstack app, heavy on SSR via Next.js or Astro, team already using Netlify for production — just use Netlify. PreviewDrop doesn't try to replace it for frontend work. If your backend is separate from your frontend, PreviewDrop handles the backend side while Netlify handles the frontend side. Many teams run both.
