Envoy vs RavenDB

Envoy logo

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

  • RavenDB is an open-source document-oriented database written in C#.
  • Envoy is free; RavenDB starts at $499/yr.
  • Only Envoy lists xDS dynamic configuration; only RavenDB lists ACID Transactions.
  • Where RavenDB falls short: the free Developer licence bars commercial use and expires every 6 months, requiring renewal.
  • 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

RavenDB

  • The free Developer licence bars commercial use and expires every 6 months, requiring renewal
  • The free Community licence caps a customer at 60 cores and forces you to stay on the latest major version
  • The Professional licence is limited to a single database, a 5 node cluster, 40 cores and 240 GB RAM
  • Sharding across nodes, ETL to OLAP, Elasticsearch and Kafka, and data archival are Enterprise only
  • Enterprise and AI licence pricing is contact us only with no published rate

Questions people ask

Is Envoy or RavenDB better?
Neither clearly leads. Envoy starts at Free and RavenDB at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Envoy or RavenDB?
Envoy starts at Free and RavenDB at Free.
Does Envoy or RavenDB run on more platforms?
Envoy runs on Web. RavenDB runs on Linux, Windows, macOS, Self-hosted, Web.
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 RavenDB is typically brought in for.
What can Envoy do that RavenDB cannot?
Envoy covers xDS dynamic configuration, Protocol breadth, Filter chain architecture, Observability by default. RavenDB covers ACID Transactions, Auto-indexing, Full-text Search, Graph Queries.

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.

RavenDB: Is RavenDB free or open source?

RavenDB is open source under the AGPLv3 license and available on GitHub. It also offers a free developer license with enterprise-level features limited to 9 cores, 36GB max RAM, 3 nodes, and non-commercial use.

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.

RavenDB: Can I use RavenDB commercially for free?

RavenDB offers a free Community License that permits commercial deployment with unlimited databases and sizes, subject to a 60-core maximum per customer and requirement to run the latest major version.

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.

RavenDB: What commercial licensing options does RavenDB offer?

RavenDB offers Professional, Enterprise, and AI tiers for commercial use. Pricing for these tiers requires contacting their sales team at [email protected].

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.

RavenDB: Does RavenDB offer a cloud hosting option?

RavenDB Cloud provides a fully managed cloud database with maintenance, failover, and backups included. Pricing is available at cloud.ravendb.net/pricing.

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.

RavenDB: Is there a refund window if I purchase RavenDB?

RavenDB offers a 30-day refund window for purchased licenses.
