This is how you unlock DORA metrics. - [GitHub integration](https://docs.periscope.sh/integrations/github.md): Connect your GitHub organization to capture PR merge events and enable SPACE metrics, service health, and contributor analytics. - [MCP server](https://docs.periscope.sh/integrations/mcp.md): Query your engineering metrics from AI coding assistants like Claude Code, Cursor, and Windsurf through the Model Context Protocol. - [OpenCode plugin](https://docs.periscope.sh/integrations/opencode.md): Track AI coding analytics — cost, tokens, models, and git context — from OpenCode sessions with the Periscope analytics plugin. - [Change failure rate](https://docs.periscope.sh/metrics/change-failure-rate.md): Percentage of deployments that fail. The third DORA metric and a key measure of release quality. - [Contributor activity](https://docs.periscope.sh/metrics/contributor-activity.md): Per-contributor engineering metrics including PR counts, sizes, cycle times, and activity patterns. - [Deployment frequency](https://docs.periscope.sh/metrics/deployment-frequency.md): How often your team deploys code to production. The first of the four DORA metrics. - [Lead time for changes](https://docs.periscope.sh/metrics/lead-time.md): Time from PR merge to production deployment. The second DORA metric and a key measure of delivery speed. - [Mean time to recovery](https://docs.periscope.sh/metrics/mttr.md): Time to recover from a failed deployment. The fourth DORA metric and a key measure of operational resilience. - [PR cycle time](https://docs.periscope.sh/metrics/pr-cycle-time.md): Time from pull request open to merge. A key measure of development efficiency and flow. - [Risk signals](https://docs.periscope.sh/metrics/risk-signals.md): Automated detection of engineering risks including bus factor, stale services, workload imbalance, and activity anomalies. - [Service health](https://docs.periscope.sh/metrics/service-health.md): Per-repository health status based on activity levels, contributor diversity, and cycle times. - [Size vs time](https://docs.periscope.sh/metrics/size-vs-time.md): Visualize the relationship between PR size and cycle time to understand how change size impacts your review process. - [Throughput](https://docs.periscope.sh/metrics/throughput.md): PRs merged per week. A measure of your team's shipping cadence and development activity. - [Quickstart](https://docs.periscope.sh/quickstart.md): Connect GitHub, send your first deployment event, and see your DORA metrics in under 10 minutes. ## Optional - [Join waitlist](https://tally.so/r/MeAqPM) - [GitHub](https://github.com/alihen)
