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.

The short version

  • LiquidPlanner is a predictive project management solution.
  • Envoy is free; LiquidPlanner starts at $15/mo.
  • Only Envoy lists xDS dynamic configuration; only LiquidPlanner lists predictive scheduling.
  • Where LiquidPlanner falls short: rebranded to Tempo Portfolio Manager; the pricing page shows no published figures, only an early access sign-up.
  • 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

Questions people ask

Is Envoy or LiquidPlanner better?
Neither clearly leads. Envoy starts at Free and LiquidPlanner at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Envoy or LiquidPlanner?
Envoy has a free tier; the other does not. Paid plans start at Free for Envoy and On request for LiquidPlanner.
Does Envoy or LiquidPlanner 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. LiquidPlanner starts at On request.
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 LiquidPlanner is typically brought in for.
What can Envoy do that LiquidPlanner cannot?
Envoy covers xDS dynamic configuration, Protocol breadth, Filter chain architecture, Observability by default. LiquidPlanner covers Predictive scheduling, Resource management, Time tracking, Analytics.

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.

LiquidPlanner: How is Tempo timesheets pricing calculated for my organization?

Pricing is per-user per month and scales based on organization size. For 1-10 users: $1.00/user; 11-100 users: $5.21/user; 101-250 users: $3.66/user; scaling down to $0.25-$0.39/user for organizations with 5,000+ users.

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.

LiquidPlanner: What license matching requirement exists for Tempo?

Your Tempo license size must match your Jira license size, with a user defined as anyone who can log into Jira.

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.

LiquidPlanner: Is there a free trial for Tempo timesheets?

Yes, Tempo offers a free trial available through the Atlassian Marketplace.

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.

LiquidPlanner: What deployment options are available for Tempo?

Both Cloud and Data Center deployment options are offered, with annual billing available.

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.
