Verification layer for CI pipelines

Run checks independently. Fail only when a quorum agrees.

QuorumCI executes deterministic checks redundantly across independent nodes. Reduce false positives by requiring agreement before failure.

View documentation How it works

How it works

Independent execution.
Collective agreement.

01

Define a check

Specify a small, deterministic task: HTTP health check, DNS lookup, TLS validation, or custom script.

02

Execute redundantly

QuorumCI runs the same check across N independent nodes, each geographically and network-isolated.

03

Quorum determines truth

Results are aggregated. A failure is reported only when M of N executions agree on the same outcome.

    check:
      type: http

    quorum: 3  # Fail only if 3 nodes agree

Job types

Built for infrastructure checks

HTTP / HTTPS

Health checks, endpoint verification, response validation. Verify status codes, response bodies, and headers.

type: http

DNS

Record lookups from multiple network vantage points. Verify propagation, detect misconfigurations.

type: dns

TLS

Certificate validation, expiry checks, chain verification. Catch certificate issues before they cause outages.

type: tls

Script

Custom Node.js or Bash scripts for complex verification logic. Stateless, short-lived, deterministic.

type: script
