Koyeb's answer

We custom-built our serverless engine with a custom stacked based on Nomad, Firecracker microVMs, and Kuma. https://www.koyeb.com/blog/the-koyeb-serverless-engine-from-kubernetes-to-nomad-firecracker-and-kuma

Koyeb's answer

We're building a platform that allows you to deploy and run full-stack apps and APIs written with your favorite framework and language without having to deal with infrastructure. No server, networking, or Kubernetes management necessary to get your apps running globally. You simply push your code to your Git repository and we handle the build process and deploy inside of Firecracker microVMs with a ready-to-use network stack.

We also wrote a blog about why we are building Koyeb: https://www.koyeb.com/blog/building-a-global-deployment-platform-is-hard-here-is-why

Faable Deploy's answer:

Two things, and the second one is the harder to copy.

Hosting and identity in one subscription. Shipping an app and adding login are normally two vendors and two bills. Faable Deploy comes with Faable Auth — a multi-tenant OAuth 2.0 / OpenID Connect identity server with social login, MFA, SSO and machine-to-machine tokens — under the same plan. There is nothing to integrate between the two and nothing extra to pay.

It is European, not merely available in Europe. The company is Spanish and the infrastructure is entirely EU-based, so GDPR data sovereignty is the default rather than a region you pick in a US provider's console.

The rest is the table stakes, done properly: link a GitHub repository, push, and the app is live with a valid certificate, autoscaling and a Web Application Firewall in front of it — no Dockerfile to write and no pipeline to configure.

Faable Deploy's answer:

Three reasons, and one honest reason not to.

• Your data stays in the EU by default. Most of the alternatives are US companies that offer a European region. Faable is a Spanish company running entirely on European infrastructure, which is a different answer when the question is data sovereignty rather than latency.
• The free plan is a plan, not a trial. It does not expire: one free instance per project, ten deployments a day, and the app sleeps after 30 minutes idle and wakes on the next request. Fly.io removed its free tier in 2024 and Railway replaced its permanent free tier with a one-off trial credit, so "free tier" is worth reading carefully across this category.
• Authentication is included, not another vendor. Faable Auth (OAuth 2.0 / OIDC, social login, MFA, SSO, machine-to-machine) is in the same subscription, so the usual second bill and second integration simply are not there.

And the honest limit: Faable Deploy runs long-lived server processes, not per-request edge functions. If your app is a frontend with a handful of serverless functions attached, Vercel and Netlify are built precisely for that shape and will feel more natural. If it is a backend that stays running — an API, a bot, a queue-backed service, an app with a database behind it — that is what this platform is for.

Faable Deploy's answer:

Developers and small teams shipping backends, not landing pages.

What people actually deploy here:

• REST and JSON APIs in Python (Flask, FastAPI, Django) and Node.js (Express, NestJS)
• Chat bots driven by inbound webhooks — Telegram, WhatsApp, Discord, Slack
• Webhook receivers sitting behind another product, such as Stripe endpoints or GitHub Apps
• LLM-backed apps and agents that stream their responses
• Full-stack apps in Next.js, Astro or Vite, when they need a running server rather than static files

Two profiles dominate. The first is the solo developer or small team who wants a side project or a first product online without becoming their own platform engineer; the free plan exists for exactly that, and it does not expire. The second is teams based in the EU, or serving EU users, for whom data residency is something a customer or a procurement form will eventually ask about in writing — not a preference.

Who it is not for: if you need per-request edge functions, or a managed Kubernetes you can tune yourself, this is deliberately not that.
