Unkey vs Heroku

Pre-calculated from hand-checked data — Unkey checked 2026-08-06, Heroku checked 2026-08-06.

The short version

Unkey and Heroku split our comparison — the right pick depends on what your project values.

Price Unkey

Unkey is cheaper at most of the stages we model.

Ease Tie

Both take similar effort to get a first deploy live.

Features Heroku

Heroku comes out ahead on 3 of the 15 features we track, versus 2.

What developers say about this matchup

We couldn't find a substantive first-person discussion comparing this exact pair. We leave the section empty instead of filling it with vendor marketing or generic SEO comparisons.

At a glance

Unkey Heroku
Best for Production APIs that want hosting, gateway policies, API keys, rate limits, and request analytics in one place. Teams that already know Heroku and value its mature workflow over price.
How deploys work Connect GitHub for automatic builds and branch previews, or deploy a Docker image from the Unkey CLI. git push heroku main; buildpacks detect the stack and the platform handles the rest.
The tradeoff It is a young, API-specific platform with metered billing, ephemeral storage, and no managed database. You pay a platform premium — comparable raw compute costs a third as much elsewhere.
Free tier None None

What you'd realistically pay

$5 $5 $18 $25 $50 $50 Just starting Steady traffic Growing
Unkey Heroku
Estimated monthly cost at each project stage. Estimates use each provider's real plans; euro prices are compared at a rough exchange rate.
Project stage Unkey Heroku Cheaper
Just starting ≈$5/mo Starter — The $5 minimum includes $5 of usage, enough for a small, lightly used API. ≈$5/mo Eco — One Eco dyno (512 MB) that sleeps after 30 idle minutes; an always-on Basic dyno is $7, and an Essential-0 Postgres adds $5. ≈ Tie
Steady traffic ≈$18/mo Starter + usage — About 0.5 active vCPU and 1 GB of memory running continuously before egress or active-key charges. ≈$25/mo Standard-1X — Adds horizontal scaling and zero-downtime deploys; database still extra. Unkey
Growing ≈$50/mo Business — The $50 minimum becomes usage credit and raises per-instance limits to 16 vCPU and 32 GB of RAM. ≈$50/mo Standard dynos + add-ons — Two Standard-1X dynos; realistic totals depend heavily on add-ons. ≈ Tie

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.

Heroku pricing notes

  • Dynos are prorated to the second up to the monthly maximum.
  • Heroku Postgres starts at $5/month (Essential-0, 1 GB storage); the Redis-compatible Key-Value Store starts at $3/month (Mini, 25 MB).

Deploy workflow

Unkey Heroku
Deploy from Git push Yes Connect GitHub; pushes to the default branch deploy production automatically. Yes git push heroku main is the original deploy story; GitHub integration too.
Preview deploys Yes Non-default branches and pull requests receive isolated preview deployments. Yes Review Apps create a running app per pull request.
Official CLI Yes The Unkey CLI deploys local build contexts or pre-built container images. Yes The heroku CLI covers deploys, logs, scaling, and add-ons.
Instant rollbacks Yes Rollbacks atomically switch traffic to a previous immutable deployment. Yes heroku releases:rollback reverts to any previous release instantly.

Platform

Unkey Heroku
Custom domains + HTTPS Yes Custom apex domains and subdomains include automatic TLS; plan limits apply. Yes Custom domains with automated certificate management on paid dynos.
Built-in CDN / edge network No The global gateway routes API traffic but is not a static-asset caching CDN. No No built-in CDN — pair with Cloudflare or Fastly yourself.
Serverless functions No Applications run as container instances rather than per-request functions. No Dynos are long-running processes; there is no function product.
Docker containers Yes Build from a Dockerfile or deploy a pre-built image from a registry. Yes Deploy container images through the Heroku container registry.
SSH / shell access No The documented workflow exposes logs and metrics, not an interactive SSH shell. Partial heroku run bash gives a one-off shell in a fresh dyno, not the live one.
EU hosting region Yes European deployment regions are available; Starter includes three regions and paid upgrades unlock all. Yes Common Runtime offers a Europe region at the same prices.

Runtime & operations

Unkey Heroku
Automatic scaling Yes Horizontal autoscaling adjusts instance count from configured minimums and maximums based on CPU load. Partial Built-in autoscaling requires Performance-tier dynos; standard dynos scale manually.
Scale to zero Partial Preview environments sleep automatically when idle; apps can also be stopped and started manually. Partial Eco dynos sleep after 30 idle minutes; Basic and Standard run continuously.
Scheduled jobs No There is no documented first-class scheduler for cron jobs. Yes Heroku Scheduler (free add-on) runs tasks on a schedule.
Managed database No No managed database is included; connect an external database service. Yes Heroku Postgres and Key-Value Store are fully managed add-ons.
Logs & metrics built in Yes Runtime logs, CPU and memory metrics, request analytics, and gateway decisions appear in the dashboard. Partial Log stream and basic metrics included; serious monitoring means add-ons.

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.

Heroku

  • There is no free tier.
  • Compute is expensive for what you get: Standard-1X costs $25/month for 512 MB of RAM.
  • Databases and other add-ons bill separately and can dominate the total.
