Envoy

  • Acting as the data plane under a service mesh or Gateway API implementation, which is how the overwhelming majority of deployments use itnot Balsamiq Wireframes
  • An edge or API gateway that needs per-route retry budgets, circuit breaking and outlier detection rather than round-robin proxyingnot Balsamiq Wireframes
  • Migrating traffic between service versions or between a monolith and its replacement, using weighted splits and shadow trafficnot Balsamiq Wireframes
  • 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 Balsamiq Wireframes

Where each one falls short

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

Balsamiq Wireframes

  • Starter plan is capped at 10 projects and costs $16 per editor per month ($192/year)
  • Teams plan raises the cap to only 100 projects at $24 per editor per month; even Enterprise tops out at 400 projects
  • AI credits are metered per editor per month (500 on Starter, 1,000 on Teams, 2,500 on Enterprise), so AI features have a hard usage ceiling beyond the base seat price

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 Balsamiq Wireframes or Envoy better?
Neither clearly leads. Balsamiq Wireframes starts at Free and Envoy at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Balsamiq Wireframes or Envoy?
Balsamiq Wireframes starts at Free and Envoy at Free.
Does Balsamiq Wireframes or Envoy run on more platforms?
Both run on Web, so platform support will not decide this one for you.
Can I use Balsamiq Wireframes for free?
Both have a free tier, so you can try either at no cost before committing.
What is Balsamiq Wireframes best used for?
Balsamiq Wireframes is most often used for creating wireframes for idea communication, prototyping interfaces faster than design tools, collaborating on wireframes with unlimited reviewers, exporting designs to pdf and images. Of those, creating wireframes for idea communication and prototyping interfaces faster than design tools are not what Envoy is typically brought in for.

Answered from the vendors’ own pages

Balsamiq Wireframes: How much does Balsamiq Wireframes cost per editor?

Balsamiq charges $16/month (Starter), $24/month (Teams), or $35/month (Enterprise) per editor when billed annually. Monthly billing costs $192/year, $288/year, or $420/year respectively. Only editors who actively make changes are counted, not viewers or stakeholders.

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.

Balsamiq Wireframes: What AI credit limits does Balsamiq provide by plan?

Starter includes 500 monthly AI credits per editor, Teams includes 1000 monthly credits per editor, and Enterprise includes 2500 monthly credits per editor. Additional on-demand credits can be purchased at $15 per 500 credits across all tiers.

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.

Balsamiq Wireframes: What are the project limits across Balsamiq plans?

Starter allows up to 10 projects, Teams allows up to 100 projects, and Enterprise allows up to 400 projects per workspace. All tiers support unlimited boards within each project.

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.

Balsamiq Wireframes: Is there a free trial for Balsamiq Wireframes?

Balsamiq offers a 14-day free trial with no credit card required for new users to evaluate the platform before committing to a paid plan.

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.

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.
