Failior dependency-graph monitoring for faster root-cause tracing
Failior ingests lightweight graph packets and displays node-level impact so SREs move from alert to likely root cause faster.
The pain point
Alerts usually describe a symptom, not where the problem lives. A 5xx spike or queue backlog tells you something is wrong but not which workflow, customer cohort, or downstream service is affected. That gap forces on-call engineers to run manual queries and chase leads.
Limited dependency visibility also multiplies risk. Real incidents from a single provider outage to untracked supply-chain vulnerabilities show how quickly impact can spread when you cannot map dependencies in real time. See Fastly's post-incident analysis and CISA guidance for examples of how hidden dependencies raise both operational and security exposure.
How Failior handles it
Failior captures minimal, structured telemetry so you can reconstruct workflows on the fly. Instrument a backend workflow with the Graph SDK or link browser RUM incidents and Failior ingests small graph packets that include graph_id, an ordered node_id_list, did_error, and timestamp. The data is intentionally compact to keep overhead low.
The UI rebuilds the execution path, highlights the failing node, and maps downstream impact so you can see blast radius and likely root cause in seconds rather than minutes. Node-level precision and optional RUM linking let you connect frontend errors to the backend paths that caused them. Full implementation details are in the docs.
What to do next
Try the live graph demo and add the Graph SDK to one critical workflow. Validate that the dashboard reconstructs the path and marks impacted nodes.
Start on the free Starter plan to evaluate behavior and alerting, then upgrade to Growth or Scale if you need longer retention, more monitors, or expanded alert coverage. See the docs and pricing pages for details.
