How Reddit grew developer docs engagement 236% year over year with Kapa
"We scaled developer documentation to 185% growth in active users and a 236% year-over-year increase in engagement, with 85% of user questions resolved at high confidence via Kapa."

Challenge
Docs feedback arrived from everywhere with no objective way to prioritize it, and no metrics existed to show the impact of documentation work.
Solution
Deploy Kapa on the Developer Platform docs and run the docs roadmap on its weekly performance stats, coverage-gap reports, and real developer questions.
Results
185% growth in docs active users
236% year-over-year increase in engagement
85% of user questions resolved at high confidence
70% above last year's total unique users by June 10
Documentation Agent
Every question feeds the docs roadmap
Live on developers.reddit.com, it answers natural-language questions with source-cited responses drawn from the Developer Platform docs, so a developer building an app or game gets the exact API, storage pattern, or configuration they need without digging through pages. Every question also feeds back into the docs themselves. Weekly performance stats and coverage gap reports show the team what developers are actually asking, turning the agent into both a support surface and the data source behind Reddit's docs roadmap.

Looking forward
The next step is agents. Reddit is enabling Kapa's docs MCP server so coding agents like Claude Code and Cursor can ground themselves in the Developer Platform docs as developers build, with agent traffic analytics revealing which tools query the docs and where they hit dead ends.
That fits a broader push: Stacy is spending the next six months turning GEO best practices into standards for Reddit's docs, making them as answerable for agents as they are for humans. As Kapa ships deeper agent capabilities, Reddit gets a head start on the next generation of developer experience, where the first reader of your docs is often not a human at all.
