Interfere

Engineering, product and design teams often learn about production bugs only after customers report them, by which point the issue may have been live for hours and affected thousands of users. Diagnosing the cause typically means digging through logs, metrics and traces by hand, then routing the problem to the right person and tracking whether a fix actually lands. The page's own example shows a password reset flow silently breaking after a deployment, error rates jumping from 0.2% to 12% within six minutes and over 12,000 users affected before the root cause (a bad route change in auth/reset.ts) is found. This reactive, manual process costs engineering teams time that could otherwise go toward building product.

Interfere continuously monitors an application's behavior and outcomes to flag problems as they emerge, rather than waiting for error reports. It goes beyond raw logs, metrics and traces to perform root cause analysis, explaining what broke, why, and which users and surfaces are impacted, as shown in its inbox view with findings, affected-user counts and activity timelines. The product also suggests fixes, links them directly to the relevant code in the repository, and tracks them through to resolution while keeping engineers in control. Listed capabilities include user tracking, logging and alerting, session replays, predictive analysis, release tracking, zero-touch triage, prioritization, team routing, multiplayer collaboration, and enterprise access controls such as SAML/OIDC SSO, SCIM provisioning, custom roles and domain whitelisting. Interfere also ships SDKs for Next.js, React, Vite, Node.js and NestJS, plus an MCP server, CLI and typed SDK for connecting agents and building custom integrations.
