Envoy

Developer Tools

The short version

  • Grafana Cloud is a fully managed observability platform.
  • Envoy is free; Grafana Cloud starts at $19/mo.
  • Only Envoy lists xDS dynamic configuration; only Grafana Cloud lists grafana Dashboards.
  • Where Grafana Cloud falls short: active Series (AS) billing model is difficult to predict and control; misconfiguration can cause sudden spikes and unexpected bills.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

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

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

Grafana Cloud

  • Active Series (AS) billing model is difficult to predict and control; misconfiguration can cause sudden spikes and unexpected bills
  • Reduced control and customization compared to self-hosted Grafana instances
  • Data sovereignty concerns for organizations requiring on-premises data retention
  • Limited reporting types compared to traditional BI tools for compliance and audit requirements

Questions people ask

Is Envoy or Grafana Cloud better?
Neither clearly leads. Envoy starts at Free and Grafana Cloud at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Envoy or Grafana Cloud?
Envoy starts at Free and Grafana Cloud at Free.
Does Envoy or Grafana Cloud run on more platforms?
Envoy runs on Web. Grafana Cloud runs on Web, API.
Can I use Envoy for free?
Both have a free tier, so you can try either at no cost before committing.
What is Envoy best used for?
Envoy is most often used for acting as the data plane under a service mesh or gateway api implementation, which is how the overwhelming majority of deployments use it, an edge or api gateway that needs per-route retry budgets, circuit breaking and outlier detection rather than round-robin proxying, migrating traffic between service versions or between a monolith and its replacement, using weighted splits and shadow traffic, standardising observability across a polyglot estate, so that latency, error rates and tracing look the same regardless of the language a service is written in. Of those, acting as the data plane under a service mesh or gateway api implementation, which is how the overwhelming majority of deployments use it and an edge or api gateway that needs per-route retry budgets, circuit breaking and outlier detection rather than round-robin proxying are not what Grafana Cloud is typically brought in for.
What can Envoy do that Grafana Cloud cannot?
Envoy covers xDS dynamic configuration, Protocol breadth, Filter chain architecture, Observability by default. Grafana Cloud covers Grafana Dashboards, Prometheus Metrics, Loki Logs, Tempo Traces.

Answered from the vendors’ own pages

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.

Grafana Cloud: What are the exact limits of Grafana Cloud's free tier?

Grafana Cloud free tier includes 10,000 active series for metrics, 50GB logs and traces per month, 3 active visualization users, and 14-day retention with community support. No credit card required.

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.

Grafana Cloud: How is Grafana Cloud billed, and what are the per-unit costs?

Grafana Cloud Pro tier starts at $19/month platform fee plus usage-based charges. Metrics cost $6.50 per 1,000 active series above free limits, logs and traces are charged per GB ingested, and visualization users are $8 per active user.

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.

Grafana Cloud: Can I use Grafana Cloud for open-source Grafana deployments?

Grafana Cloud is the managed cloud service version. Open-source Grafana is free and can be self-hosted indefinitely on your own infrastructure.

Source
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.

Grafana Cloud: What observability signals does Grafana Cloud include?

Grafana Cloud includes metrics (via Mimir), logs (via Loki), traces (via Tempo), profiles, and synthetics, with unified querying and visualization across all signals.

Source
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.

Grafana Cloud: Does Grafana Cloud include alerting and how is it priced?

Yes, Grafana Alerting is included at no additional charge across all tiers. Rule storage, evaluation, and notification delivery are covered by the platform fee with no per-alert or per-notification fees.
