Crawltic is the developer-first experimentation platform: a full REST/GraphQL API, an MCP server, and a CLI — built to compare any custom metric with real statistical rigor. No dashboard required.
Crawltic hashes each visitor to a variant at the edge in under 4ms, keeps them there, and tallies every conversion against the lane they landed in. What you're watching is the exact model the engine runs.
Crawltic is API-first. Every feature in the UI is also a one-line call.
Create experiments, assign variants, and log any custom event or metric — revenue, latency, retention, whatever matters to you.
Plug Crawltic into Claude, Cursor, or any MCP client. Ask your agent to spin up, monitor, or ship an experiment.
crawltic experiments create — script your entire testing workflow from CI, cron, or your terminal.
Bayesian + frequentist stats, sequential testing, guardrail metrics, and automatic sample-size calculators.
Not just clicks. Pipe in revenue, EPC, churn, latency, LTV — compare variants on whatever you define as a win.
Set confidence thresholds and sample quotas. Crawltic ships, pauses, or rolls back the moment the numbers say so.
Each variant is a probability distribution, not a single number. As evidence arrives, the curves tighten and pull apart — and Crawltic tells you exactly how likely B is to beat A.
Probability-to-beat-control tracked live, then an automatic ship once your thresholds clear.
Recalculated every minute · auto-ships the moment the last quota clears
Headline, CTA, price anchor, layout — run them together and Crawltic isolates the contribution of each one. The grid shows measured lift per variable, per variant, updating as traffic lands.
Lift re-ranks as data arrives. Every assignment and conversion streams through the same event log your API reads.

"We replaced two dashboard-only tools with Crawltic's API. Our data team ships experiment logic straight from our pipeline now."
