11/11 In that sense, full-stack session recordings become a new kind of documentation: Captured from reality. AI-native. Immediately debuggable.
The future of API documentation is augmenting it with reality.

10/ This is why session-based visibility solves this issue:
When you can see:
user action → request → trace → response → downstream effects
… you’re no longer guessing.
Behavior becomes a first-class artifact.

9/ What teams need now isn’t better documentation of intent.
They need visibility into behavior:
• which user triggered the call
• what happened before and after
• which services were involved
• what the system actually returned
That context doesn’t live in static docs.

8/ Here’s the pattern:
Every generation of API docs made it easier to call APIs correctly.
None of them made it easier to understand why something broke in production.
Debugging kept living outside the docs.

7/ In the 2020s, developer catalogs appeared: Backstage, Compass, Cortex.
They brought: ownership, versioning, metadata, discovery.
Helpful, but still separate from execution.

6/ ****Interactive docs (Swagger UI, Postman) were the next step forward.
You could experiment. See responses. Try parameters.
Great for learning and testing.
But still:
• not state-aware
• not tied to real users
• not integrated with debugging
• hard to represent real workflows

5/ In the 2010s, the OpenAPI Specification changed the game.
Machine-readable specs. Auto-generated docs. Consistency.
For the first time, documentation could stay in sync structurally.
… But it still described what should happen, not what did happen.

4/ Then came documentation generators (e.g. Javadoc, Doxygen). In short: auto-generated docs from code comments and annotations.
A big step forward, but still describing intent, not behavior.
The system could drift. The docs wouldn’t notice.

3/ REST APIs made things simpler in the mid-2000s: docs moved to HTML pages and wikis like Confluence and MediaWiki.
More readable. Still manual. Still static.
Better for humans. Still disconnected from reality.

2/ In the 90s and early 2000s, APIs were documented as static artifacts (HTML pages, PDFs, WSDL files).
Accurate, but rigid. Hard to read. Harder to keep up to date.
Useful for reference. Except when things broke.

We built Multiplayer to solve this.
For teams debugging modern applications, the difference is night and day:
✅ Support teams resolve issues without escalating to engineering
✅ Engineers get complete context to fix bugs faster
✅ AI can actually help debug because it sees the full stack
