How do I share a playground session?

Click the Share icon in the playground toolbar. Select which elements to include — operation, variables, and headers. Copy the generated URL.

What is included in a shared link?

The operation is always included. Variables and headers are optional. Pre-flight, pre-operation, and post-operation scripts are not included.

Can anyone open a shared link?

The link encodes the operation, plus any variables and headers you chose to include. Anyone with the link can read that encoded content, so do not include sensitive credentials or tokens in shared headers.

Are headers safe to include in shared links?

Headers are encoded in the URL and accessible to anyone with the link. Avoid including sensitive credentials or tokens in shared headers.

Does the session open in the same tab?

No. The shared session opens in a new tab, leaving the sender's current session unchanged.

Are scripts included in the shared link?

No. Pre-flight, pre-operation, and post-operation scripts are not included in shared playground links.

Shared Playground State for GraphQL | Cosmo by WunderGraph

The problem

GraphQL context gets lost in translation

Sharing a query means sharing the operation, the variables, and the headers. Without all three, the recipient cannot reproduce the session.

Sharing queries means copy-pasting across chat tools

Queries sent in Slack miss variables. Headers are forgotten. The recipient spends time reconstructing context before they can even run the request.

Bug reports without reproduction steps waste time

An issue that says "this query returns wrong data" cannot be investigated without the exact query, variables, and headers. Getting that context requires back-and-forth.

Onboarding requires walking through query setup manually

A senior engineer cannot hand a new team member a working example without a meeting. There is no way to pre-configure a playground session for someone else.

Our solution

A URL that encodes the complete session

Shared Playground State generates a URL that encodes the operation, variables, and headers from your current session. Recipients open the link and see the exact state you configured, ready to execute.

From session to shareable link

Click the Share icon in the playground toolbar.
Choose which elements to include: the operation is always included. Variables and headers are optional.
The playground compresses and encodes the selected state into a URL.
Copy the link and send it via Slack, email, or a documentation page.
Recipients open the link. The playground restores the session into a new tab.
The session opens ready to execute — no manual setup required.

One click. One link. Full session context.
