Free vs paid — side by side

Two short live walkthroughs with on-screen commentary. Compare what you get without a key and what unlocks after payment.

14-day full-product demo — once per email. Requested on the website (form below), not from the IDE. After expiry IDE data is reset — back up first.

3.0.0

New in 3.0.0

What this line adds. The full log is on the changelog page.

Server-Sent Events

Listen to an event stream next to WebSocket. Included on Free.

HAR import

Recordings from DevTools or a proxy become a collection. Included on Free.

Live Capture

After you click, requests from one browser tab can be imported into the collection.

Secret warning on export

When you export, the IDE warns if values look like secrets: download as-is, redact, or cancel.

Folder export

One file per request — easy to drop into your own repository. Paid plans.

Patches from an assistant

Incoming edits: a list of operations, apply or reject. Paid plans. There is no built-in MCP server.

Public collection link

The site shows the name and request list, not headers or bodies. Paid plans; up to one day, not forever.

Full response and tree

Send shows the full response body; large trees scroll more smoothly; the Params / Response splitter can be dragged again.

Full changelog

Capabilities

Everything for APIs in one window

Built for manual testing, scenario automation and load runs. Free starts without a key. Paid plans unlock the full set.

Multi-protocol

REST, GraphQL, WebSocket, SOAP and gRPC in one window.

Spec import

OpenAPI, WSDL, .proto, AsyncAPI, Postman and curl.

Local-first

Collections and tokens stay in the browser. Free needs no account and no mandatory cloud; a client_id appears only if you opt into a server feature.

Variables & environments

Merge order environment → space → collection → request. Empty values do not wipe lower layers.

Authorization

Inherit from folder and collection: Bearer, Basic, API key, OAuth2, JWT, Digest, AWS. {{token}} placeholder.

Workspaces

Multiple spaces, collections and environments side by side.

Scripts

Pre/After scripts, variables and response checks.

Collection Runner

Run a collection or folder: Functional (iterations, data file) and Performance. Stop on error.

QA scenarios

Checks after Send on Free; scenarios, negative cases and “File a bug” are paid. Free: 3 collection and 3 folder runs per month.

Load testing

Load tab on Free (1 run per month). Collection/folder runner, Fixed / Ramp up / Spike / Peak, RPS/p95 and metric export — full set on paid plans.

Proxy

Proxy at request, collection or space level; separate proxy per AI provider.

AI assistant

Ask / Explain for requests and load; multi-provider AI chat; design a collection with AI. Server history: truncated text with secrets, passwords, tokens and personal data stripped; attachment bytes are not stored.

Collection and folder patches

Export and apply patches (not diffs) for a collection, folder or request.

PDF reports

QA and load reports straight from the IDE.

IDE backup

Snapshots locally, to the server or by email.

Integrations

Multiple issue trackers and messengers for teams.

FAQ

Questions and answers

Straight answers about the product, plans, data safety and the usual fears before installing an API client in Chrome.

What is PolyApiIDE and why not just use Postman?

It is an HTTP client and API IDE inside Chrome: REST, GraphQL, WebSocket, SOAP and gRPC, collections, environments, QA scenarios and load tests. You do not need a heavy desktop app or a vendor account to send a request.

Postman is stronger as a cloud platform for large teams. PolyApiIDE is built for local-in-browser work, fast import of existing collections, and a one-time Lifetime purchase if you do not want a subscription.

Do I need to register or create an account?

No account is required. Free opens immediately after install, with no registration window. Email is needed at website checkout (Month / Year / Lifetime), when activating an already purchased key, or if you opt into a cloud feature. Paid features and cloud services create a technical client_id (API client identifier) — not a store account and not a password login. Activate the key under Settings → License.

Is Free a crippled demo?

Free is a real daily driver: workspaces, collections, Send, environments, variables, basic auth, poly/pm scripts, import of OpenAPI, WSDL, GraphQL, .proto, AsyncAPI, Postman, curl, Insomnia, Hoppscotch and Thunder, JSON tree, curl preview, fullscreen response and the action log. Sample files: polyapiclient.ru/examples/. Limits: up to 2 active sessions, and no QA scenarios, runner, load, AI or collection patches. Cloud backup on Free is optional (last 3 versions) if you create a technical API client; paid plans keep the last 10.

If manual requests and collection import are enough, stay on Free. Paid plans are for automation, load and team patches.

Where do my tokens, collections and bodies go? Can you see my API?

Collections, environments, history and responses live in chrome.storage on your machine. We do not receive request contents on a normal Send.

polyapiclient.ru only sees what you opt into: key activation, manual cloud backup, AI chat history (truncated text after secrets and personal data are stripped), support tickets. Cloud backup is never pulled in the background. Details are in the privacy policy.

Separately, the browser (Chrome, Firefox, Edge) may collect its own data under the vendor’s privacy policy. We are not responsible for that processing; it is not governed by our documents.
