Envoy

Developer Tools

A high-performance L7 proxy written in C++ that is configured by an API rather than a config file, and is usually deployed under a control plane.

What people use each for

The jobs each tool is most often brought in to do.

Celonis

  • Process mining and analyticsnot Envoy

Envoy

  • Acting as the data plane under a service mesh or Gateway API implementation, which is how the overwhelming majority of deployments use itnot Celonis
  • An edge or API gateway that needs per-route retry budgets, circuit breaking and outlier detection rather than round-robin proxyingnot Celonis
  • Migrating traffic between service versions or between a monolith and its replacement, using weighted splits and shadow trafficnot Celonis
  • Standardising observability across a polyglot estate, so that latency, error rates and tracing look the same regardless of the language a service is written innot Celonis

Where each one falls short

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

Celonis

  • Celonis does not publish pricing on their pricing page or website
  • Company directs customers to contact sales team for pricing information
  • No indication of pricing tiers, starting prices, or quote-based model on public pages
  • Pricing inquiry requires using a contact form or reaching out directly

Envoy

  • The configuration surface is very large and hand-written bootstrap YAML runs to hundreds of lines for routing that Nginx expresses in twenty, which is why nearly every production deployment sits under a control plane and inherits that control plane's constraints as well
  • xDS is the real API and it is not stable in the comfortable sense; the v2 API set was removed outright, resource types continue to be deprecated, and your control plane and Envoy binaries have to be upgraded roughly in step or the proxies stop accepting configuration
  • Extending it properly means writing a C++ filter and building and maintaining your own Envoy binary; the alternatives are Lua, which adds per-request overhead, and proxy-wasm, whose ABI has remained effectively experimental for years with a real performance cost
  • At sidecar density the per-proxy memory and CPU footprint is a measurable share of cluster capacity, since thousands of workloads each carry a full proxy, and this is precisely the cost that has pushed mesh projects towards node-level or ambient architectures
  • There is no single vendor selling support for Envoy itself; you get the community plus control-plane vendors such as Solo.io and Tetrate, so an Envoy-level production bug is your own engineers in a C++ codebase unless a support contract happens to cover it
  • Diagnosing why a request got a particular response involves reading config dumps, the stats endpoint and the RESPONSE_FLAGS codes in access logs rather than a readable error, which is a specific skill you must hire or spend months growing

Questions people ask

Is Celonis or Envoy better?
Neither clearly leads. Celonis starts at On request and Envoy at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Celonis or Envoy?
Envoy has a free tier; the other does not. Paid plans start at On request for Celonis and Free for Envoy.
Does Celonis or Envoy run on more platforms?
Both run on Web, so platform support will not decide this one for you.
Can I use Envoy for free?
Yes. Envoy has a free tier, so you can try it without paying. Celonis starts at On request.
What is Celonis best used for?
Celonis is most often used for process mining and analytics. Of those, process mining and analytics is not what Envoy is typically brought in for.
What can Celonis do that Envoy cannot?
Envoy covers xDS dynamic configuration, Protocol breadth, Filter chain architecture, Observability by default.

Answered from the vendors’ own pages

Celonis: How much does Celonis cost?

Celonis does not publish pricing on their website. The company offers process mining and analytics solutions but requires customers to contact their sales team or use the Get in touch form on their pricing page to receive custom pricing quotes.

Source
Envoy: Should I run Envoy on its own, or under a control plane?

Almost always under one. Directly authoring xDS or static bootstrap configuration is viable for a handful of routes and becomes unmanageable beyond that. Envoy Gateway, Istio, Contour, Gloo and Consul all exist to generate that configuration for you.

Celonis: What is Celonis' pricing model?

Celonis' pricing model and pricing tiers are not publicly disclosed. Customers must request pricing information directly from Celonis through their sales contact channels.

Source
Envoy: How does it compare with Nginx or HAProxy?

Envoy is dynamically configured over an API and instrumented far more heavily; Nginx and HAProxy are faster to configure and lighter for straightforward reverse proxying. If you never need to change routing without a reload, Envoy is more machinery than the problem requires.

Celonis: Does Celonis offer a free trial or demo?

Celonis offers resources through Celonis Academy for training and has specialized programs (Academic Alliance, Aspire, Labs), but specific pricing for trials or demos is not disclosed. Contact Celonis directly for information on trial availability and pricing.

Source
Envoy: What does it cost?

Nothing to licence; it is Apache 2.0 and there is no paid edition. The cost is engineering time and, for most organisations, a commercial control plane or cloud service that packages it.

Envoy: Can I write extensions without C++?

You can write Lua filters or proxy-wasm modules in Rust, Go, C++ or AssemblyScript. Both carry per-request overhead compared with a native filter, and the Wasm path has been slower to stabilise than the project originally projected.

Envoy: Is it a CNCF project?

Yes, it is a graduated CNCF project licensed under Apache 2.0, which means the trademark and governance sit with the foundation rather than with Lyft or any vendor.
