Is Linkerd or Semgrep better?

Neither clearly leads. Linkerd starts at Free and Semgrep at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Linkerd or Semgrep?

Linkerd starts at Free and Semgrep at Free.

Does Linkerd or Semgrep run on more platforms?

Linkerd runs on Kubernetes, Linux. Semgrep runs on web, api, linux, mac, windows.

Can I use Linkerd for free?

Both have a free tier, so you can try either at no cost before committing.

What is Linkerd best used for?

Linkerd is most often used for adding mutual tls between services to satisfy a compliance requirement, getting per-service latency and success rates without instrumenting applications, progressive delivery with traffic splitting during rollouts. Of those, adding mutual tls between services to satisfy a compliance requirement and getting per-service latency and success rates without instrumenting applications are not what Semgrep is typically brought in for.

What can Linkerd do that Semgrep cannot?

Linkerd covers Automatic mutual TLS, Golden metrics, Rust micro-proxy, Traffic policy. Semgrep covers Static code scanning, Supply chain scanning, Secrets detection, Cross-file analysis.

The short version

Each has a real cost: Linkerd deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits; Semgrep free tier caps out at 10 contributors and 10 repositories.
They diverge on capability: Linkerd covers Automatic mutual TLS, Semgrep covers Static code scanning.
Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Linkerd

Deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits
Kubernetes only, with no story for workloads outside a cluster
A sidecar per pod is still real memory and latency overhead, however small, and a mesh is another layer to debug during incidents

Semgrep

Free tier caps out at 10 contributors and 10 repositories.
Secrets scanning is priced as a separate module ($15/contributor) from Code and Supply Chain.
Self-managed repositories and custom CI/CD require the Enterprise tier.
AI credits are limited per tier and additional usage requires upgrading.

Answered from the vendors’ own pages

Linkerd: Is Linkerd free?

The open-source project is free. Buoyant, its maintainer, sells enterprise distributions and support separately.

Semgrep: What does Semgrep cost?

The Free edition covers up to 10 contributors; Teams starts at $30/contributor/month for Code scanning (Supply Chain also $30, Secrets $15); Enterprise is custom-priced.

Linkerd: Linkerd or Istio?

Linkerd trades features for simplicity, with a smaller proxy and far less configuration. Istio is more capable and correspondingly more work to run.

Semgrep: Is there a free plan, and what are its limits?

Yes, the Free edition supports up to 10 contributors and 10 repositories with Code and Supply Chain scanning plus 60 AI credits total.

Source

Linkerd: Do I need a service mesh at all?

Only if you need mutual TLS, uniform retries or per-service traffic metrics across many services. For a handful of services it is usually more machinery than the problem justifies.

Semgrep: How is usage metered?

Pricing is per contributor, defined as someone who made at least one commit to a scanned private repository in the past 90 days.

Source

Semgrep: Is there special pricing for startups?

Yes, Semgrep offers special startup pricing upon request for early-stage companies.
