Comparison
Postman is where you test a request. Elva is where your API lives.
Both let you call an endpoint. Only one reads your repo, scores every endpoint, enforces a contract per audience, and runs the MCP server your agents connect to.

PostmanAPI CLIENT
A workspace where people build and send requests. Collections are maintained by hand, they describe what someone typed, and they drift from the code the moment nobody updates them.Starts from a collection someone wrotePer-seat pricing, per-collection limitsGovernance is a report, not a gate
ElvaAPI MANAGEMENT
A system of record that reads your repo, writes the specs, scores every endpoint, and enforces one contract per audience at runtime. Collections are an output, not the input.Starts from the code, rescanned every commitFlat pricing, unlimited members and endpointsGovernance blocks the publish
Four real differences
The gaps that matter once agents show up
01The code is the source, not a saved request
A collection records what someone typed into a client once. Code changes every day, so the two drift apart quietly until a consumer breaks.POSTMANYou import a spec or build requests by hand. Keeping them current is somebody’s job, and it is the first job to slip.
ELVAElva reads routes, handlers, and types from the repo, writes the OpenAPI you never had, and rescans on every commit. Nothing to maintain.
02A score and a fix, not just a document
Knowing an endpoint exists is the easy part. Knowing whether it is safe to expose to a partner or an agent is the work.POSTMANDocumentation and linting tell you the spec is well formed. Whether the API is actually ready for a consumer is still a human judgment call.
ELVAEvery endpoint is graded on design, developer experience, AI readiness, security, and performance, with a concrete fix attached and an AI that can apply it.
03Governance that can say no
A breaking change is not a documentation problem. It is a decision that needs an owner and, sometimes, a block.POSTMANChanges are reported and versioned. Nothing stops a breaking change from reaching a consumer who depended on the old shape.
ELVAContracts define what each audience sees per field. Breaking changes block the publish until approved, and the gateway enforces the same rules at runtime.
04The MCP server is the product, not an export
Agents do not read your docs. They call tools, retry badly, and act on whatever schema you hand them.POSTMANYou can generate an MCP server from a collection. Hosting, per-tool scopes, key management, and call logs are outside the picture.
ELVAHosted MCP servers with OAuth2, per-tool scopes, field redaction, rate limits, and a full log of which agent called which tool, in one place.

Switching
You do not have to throw anything away
Import your collections, keep the ones your team likes, and let Elva fill in everything the collections never covered. Most teams run both for a week and then stop opening the other one.
01Import collections and specsPostman collections, OpenAPI files, environments. Everything lands in the catalog with its history intact.
02Connect the repoThis is where the gap shows. Expect to find endpoints no collection ever mentioned, usually a third of your surface.
03Export back out any timeElva generates Postman collections as a deploy target. No lock-in, and your team keeps the client they already know.
WHEN POSTMAN IS ENOUGHYou have one small service, a handful of consumers you can name, and no agents calling anything. A collection and a shared workspace will carry you a long way, and we would rather you keep your money.
WHEN YOU NEED ELVANobody can list every endpoint you own. A partner or an agent depends on your response shape. Someone asks which agent called what, and the honest answer is that you do not know. That is the day a client stops being enough.
FAQ
Does Elva replace Postman?
They do different jobs. Postman is a client workspace where people build and send requests; Elva is the system of record generated from your code. Most teams keep a client for debugging and move the catalog, contracts, and MCP hosting to Elva.
Can I import my Postman collections?
Yes. Collections import into the catalog with their history intact, and Elva fills in what a hand-maintained collection never covered: generated specs, scoring, and change detection.
How does pricing differ from Postman?
Postman charges per seat. Elva plans are flat per workspace with unlimited members, so adding a reviewer or a stakeholder never costs anything.
