Is Cilium or Heroku better?

Neither clearly leads. Cilium starts at Free and Heroku at $5/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Cilium or Heroku?

Cilium has a free tier; the other does not. Paid plans start at Free for Cilium and $5/month for Heroku.

Does Cilium or Heroku run on more platforms?

Cilium runs on Kubernetes, Linux. Heroku runs on Web, Api, Workers.

Can I use Cilium for free?

Yes. Cilium has a free tier, so you can try it without paying. Heroku starts at $5/month.

What is Cilium best used for?

Cilium is most often used for kubernetes networking at a scale where iptables-based cni performance degrades, network policy expressed on workload identity rather than fragile ip rules, seeing which services actually talk to each other, and what policy is dropping. Of those, kubernetes networking at a scale where iptables-based cni performance degrades and network policy expressed on workload identity rather than fragile ip rules are not what Heroku is typically brought in for.

What can Cilium do that Heroku cannot?

Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. Heroku covers Git-based deployment, Buildpacks, Dynos (containers), Add-ons marketplace.

The short version

Only Cilium has a free tier, so it costs nothing to try first.
Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Heroku there is no free dyno tier; the cheapest Eco dyno is $5 per month
They diverge on capability: Cilium covers eBPF datapath, Heroku covers Git-based deployment.
Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cilium

Requires a recent Linux kernel, which rules out older distributions and some managed environments
eBPF is genuinely hard to debug when it misbehaves, and the skill is rare on most teams
Broad scope — CNI, policy, mesh, observability — means the learning curve covers several domains at once

Heroku

There is no free dyno tier; the cheapest Eco dyno is $5 per month
Eco dynos sleep after 30 minutes of inactivity, are restricted to personal accounts and allow only 2 process types
Free SSL and 10 process types start at the Basic dyno at $7 per month
Private and Shield dyno types require a Private Space, which is billed on top of the dynos
Private Space dynos start at $250 per month for Private-M and $500 per month for Private-L
Dyno prices are per dyno per month, so an app with several process types multiplies the bill

Answered from the vendors’ own pages

Cilium: Is Cilium free?

Yes, open source and CNCF-graduated. Isovalent sells an enterprise distribution and support.

Heroku: How much does Heroku cost?

Heroku dyno pricing starts at $5 per month USD for the Eco tier (with 30-minute inactivity sleep), $7 per month for Basic (always-on), and scales up to $1,500 per month for Performance-2XL with 126 GB RAM.

Source

Cilium: What does eBPF change?

It lets Cilium run packet-processing programs inside the kernel instead of relying on iptables rule chains, which behave poorly as the number of services grows.

Heroku: What is the cheapest always-on Heroku plan?

The Basic Dyno at $7 per month USD is Heroku's cheapest always-on container option. It provides 0.5 GB RAM, free SSL, and support for 10 process types.

Source

Cilium: Does Cilium replace a service mesh?

It can cover much of what a mesh does without sidecars, though full mesh feature sets still favour Istio or Linkerd.

Heroku: How is Heroku Postgres priced?

Heroku Postgres Essential tier (shared resources) starts at $5-$20 per month for 1-32 GB disk. Standard tier (dedicated) ranges $50-$12,000 per month. Premium, Private, Shield, and Advanced tiers offer higher performance at corresponding prices.
