Envoy

Technology

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

  • Only Envoy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Alkami pricing is per registered user with contractual minimums, so institutions with many enrolled but dormant users pay for accounts that never log in.; 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.
  • They diverge on capability: Alkami covers Retail digital banking, Envoy covers xDS dynamic configuration.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

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

Alkami

  • A credit union replacing the weak digital banking bundled with its core contractnot Envoy
  • A community bank that needs commercial entitlements and approvals its core vendor does not providenot Envoy
  • An institution wanting digital account opening and digital banking from one vendor after the MANTL acquisitionnot Envoy
  • A bank competing for deposits online and needing an onboarding funnel that works on mobilenot 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 Alkami
  • An edge or API gateway that needs per-route retry budgets, circuit breaking and outlier detection rather than round-robin proxyingnot Alkami
  • Migrating traffic between service versions or between a monolith and its replacement, using weighted splits and shadow trafficnot Alkami
  • 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 Alkami

Where each one falls short

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

Alkami

  • Pricing is per registered user with contractual minimums, so institutions with many enrolled but dormant users pay for accounts that never log in.
  • Alkami is a channel layer, not a core, so functionality is bounded by what the core exposes, and a poor core integration produces a slow product no amount of channel work fixes.
  • Implementation typically runs six to twelve months and requires institution staff time, which small credit unions consistently underestimate.
  • The MANTL acquisition adds account opening but also another integration programme, and consolidating on one vendor removes leverage to swap a weak module for a best of breed alternative.
  • Buying digital banking separately from the core vendor means you own the integration risk between two suppliers who will each blame the other when something breaks.

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 Alkami or Envoy better?
Neither clearly leads. Alkami 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, Alkami or Envoy?
Envoy has a free tier; the other does not. Paid plans start at On request for Alkami and Free for Envoy.
Does Alkami or Envoy run on more platforms?
Alkami runs on Web, iOS, Android. Envoy runs on Web.
Can I use Envoy for free?
Yes. Envoy has a free tier, so you can try it without paying. Alkami starts at On request.
What is Alkami best used for?
Alkami is most often used for a credit union replacing the weak digital banking bundled with its core contract, a community bank that needs commercial entitlements and approvals its core vendor does not provide, an institution wanting digital account opening and digital banking from one vendor after the mantl acquisition, a bank competing for deposits online and needing an onboarding funnel that works on mobile. Of those, a credit union replacing the weak digital banking bundled with its core contract and a community bank that needs commercial entitlements and approvals its core vendor does not provide are not what Envoy is typically brought in for.
What can Alkami do that Envoy cannot?
Alkami covers Retail digital banking, Business banking, Digital account opening, Payments and money movement. Envoy covers xDS dynamic configuration, Protocol breadth, Filter chain architecture, Observability by default.

Answered from the vendors’ own pages

Alkami: Does Alkami replace our core?

No. It is the digital channel and account opening layer on top of a core such as Fiserv, Jack Henry or FIS.

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.

Alkami: How is it priced?

Per registered user per month on multi year contracts with minimums, so model your enrolled user count rather than your active user count.

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.

Alkami: What did the MANTL acquisition change?

It brought deposit account opening in house, announced February 2025 at $400 million enterprise value, so account opening and digital banking can come from one vendor.

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.
