At a glance
| Unkey | Azure App Service | |
|---|---|---|
| Best for | Production APIs that want hosting, gateway policies, API keys, rate limits, and request analytics in one place. | Teams in the Microsoft ecosystem — .NET shops, enterprise-adjacent projects, or anyone whose employer already pays for Azure. |
| How deploys work | Connect GitHub for automatic builds and branch previews, or deploy a Docker image from the Unkey CLI. | Connect GitHub Actions from the portal, push to a local git remote, or run `az webapp up` — runtime stacks for Node, Python, .NET, PHP, and Java are built in. |
| The tradeoff | It is a young, API-specific platform with metered billing, ephemeral storage, and no managed database. | Capable and git-friendly, but you pay PaaS prices per plan and navigate the most complicated tier system here. |
| Free tier | None | F1 Free tier: 1 GB RAM, 60 CPU-minutes/day, no custom domain or SLA. Plus a $200/30-day new-account credit. |
What you'd realistically pay
Unkey Azure App Service
| Project stage | Unkey | Azure App Service | Cheaper |
|---|---|---|---|
| Just starting | ≈$5/mo Starter — The $5 minimum includes $5 of usage, enough for a small, lightly used API. | ≈$13.14/mo B1 Basic (Linux) — 1 core, 1.75 GB RAM, 10 GB storage, custom domains and SSL, 99.95% SLA. West Europe pricing. | Unkey |
| Steady traffic | ≈$18/mo Starter + usage — About 0.5 active vCPU and 1 GB of memory running continuously before egress or active-key charges. | ≈$32/mo B1 + managed PostgreSQL — ~$13 B1 Linux plus ~$19 for the cheapest PostgreSQL Flexible Server (B1ms + 32 GiB storage). | Unkey |
| Growing | ≈$50/mo Business — The $50 minimum becomes usage credit and raises per-instance limits to 16 vCPU and 32 GB of RAM. | ≈$84/mo P0v3 + managed PostgreSQL — ~$65 Premium P0v3 (1 vCPU, 4 GB, autoscale and slots) plus ~$19 for managed PostgreSQL. | Unkey |
Unkey pricing notes
- Usage rates are $0.000006944 per vCPU-second, $0.000003472 per GB-second of memory, $0.00000006 per GB-second of ephemeral disk, and $0.05 per GB of egress.
- API-key authentication through the gateway adds $0.002 per active key each month. The plan minimum is included usage credit rather than an extra charge on top.
- Log retention is 3 days on Starter, 7 days on Pro, and 14 days on Business.
Azure App Service pricing notes
- Prices are West Europe, per App Service Plan (~730 h/month); they vary by region.
- Windows plans cost roughly 4× Linux at the Basic tier because the license is baked in.
- Bandwidth: first 100 GB/month free, then about $0.087/GB.
- Savings plans and reservations cut Premium prices by up to ~55%.

Deploy workflow
| Unkey | Azure App Service | |
|---|---|---|
| Deploy from Git push | Yes Connect GitHub; pushes to the default branch deploy production automatically. | Yes GitHub Actions wired from the portal, local git push, or ZIP deploy. |
| Preview deploys | Yes Non-default branches and pull requests receive isolated preview deployments. | Partial Deployment slots (Standard tier and up) give staging environments, but no automatic PR previews. |
| Official CLI | Yes The Unkey CLI deploys local build contexts or pre-built container images. | Yes `az webapp up` deploys an app in one command. |
| Instant rollbacks | Yes Rollbacks atomically switch traffic to a previous immutable deployment. | Partial Slot swaps revert instantly on Standard+; Basic and Free redeploy the old build instead. |
Platform
| Unkey | Azure App Service | |
|---|---|---|
| Custom domains + HTTPS | Yes Custom apex domains and subdomains include automatic TLS; plan limits apply. | Yes Custom domains with managed certificates from the B1 tier up. |
| Built-in CDN / edge network | No The global gateway routes API traffic but is not a static-asset caching CDN. | Partial Azure Front Door / CDN integrate but are separate billed services. |
| Serverless functions | No Applications run as container instances rather than per-request functions. | Partial Azure Functions is a sibling product and can even run on the same plan, but it is not part of App Service itself. |
| Docker containers | Yes Build from a Dockerfile or deploy a pre-built image from a registry. | Yes Custom containers are first-class on Linux plans. |
| SSH / shell access | No The documented workflow exposes logs and metrics, not an interactive SSH shell. | Partial Browser and CLI SSH into the app container — not a VM you own. |
| EU hosting region | Yes European deployment regions are available; Starter includes three regions and paid upgrades unlock all. | Yes West Europe, North Europe, Germany, France, Sweden, Poland, Italy, Spain, and more. |
Runtime & operations
| Unkey | Azure App Service | |
|---|---|---|
| Automatic scaling | Yes Horizontal autoscaling adjusts instance count from configured minimums and maximums based on CPU load. | Partial Rule-based autoscale from the Standard tier; smarter automatic scaling needs Premium. |
| Scale to zero | Partial Preview environments sleep automatically when idle; apps can also be stopped and started manually. | No Paid plans bill continuously; only the free F1 tier unloads idle apps (with cold starts). |
| Scheduled jobs | No There is no documented first-class scheduler for cron jobs. | Yes WebJobs run scheduled and background tasks inside the plan. |
| Managed database | No No managed database is included; connect an external database service. | Yes Azure Database for PostgreSQL/MySQL from ~$19/month, plus SQL Database and Cosmos DB. |
| Logs & metrics built in | Yes Runtime logs, CPU and memory metrics, request analytics, and gateway decisions appear in the dashboard. | Yes Application Insights is deeply integrated — but ingestion bills per GB. |
Watch out for
Unkey
- Unkey only launched public app hosting in 2026, so its production track record is much shorter than established platforms such as Heroku, Render, or Railway.
- The monthly plan price is a minimum with matching usage credit, not a compute bundle: CPU, memory, ephemeral disk, egress, and active keys are metered separately.
- Storage is ephemeral and there is no managed database, so persistent data must live with another provider.
Azure App Service
- A Windows B1 plan costs ~$55/month versus ~$13 for the same tier on Linux — and default tooling sometimes nudges you toward Windows.
- You pay per App Service Plan, not per app: a second plan doubles the bill even if both are nearly idle.
- The free F1 tier has a hard 60 CPU-minutes/day quota that silently stops your app when exhausted.
- Ride-along services (Application Insights ingestion, Defender for Cloud) show up as surprise line items.
- The spending cap only exists on credit subscriptions (free trial, MSDN) — pay-as-you-go has alerts only.
