How we fit together

Faultlines + Swarmia

Swarmia tracks how your team works — DORA, SPACE, cycle time. Faultlines tracks what your team works on — features, hotspots, code health. Combine them and “why is cycle time up?”has a real answer . Use both, or Faultlines alone for the code side.

What Swarmia does best

The engineering-leader tool of choice. DORA, SPACE, and flow metrics with surveys, investment-area breakdowns, and GitHub/Jira/Slack integration. EM and VP Eng audiences trust Swarmia for executive reporting.

  • DORA + SPACE + flow metrics
  • Sprint cadence + cycle-time dashboards
  • Investment-area breakdowns + surveys
  • GitHub / Jira / Slack integration
  • Built for EM / VP Eng executive reporting
What Faultlines adds

Code-grounded answers instead of survey-based ones. Swarmia tells you “Team A’s cycle time is up 18%.” Faultlines tells you which features are decaying and why the number moved. Different question, same engineering org.

  • Feature + flow map of the codebase
  • Hotspots, churn, ownership per feature
  • Sentry + PostHog attribution per feature
  • MCP server for Cursor, Claude Code, Cline, Aider
  • Flat per-org pricing from $19/mo
Using both

How they actually combine

1
Swarmia surfaces “Team A’s PR cycle time has risen from 1.2d to 2.4d over 6 weeks.”
2
Faultlines tells you Team A owns 3 features. The Billing feature has gained 4 hotspots, lost 4pp coverage, and Sentry errors are up 22%.
3
The retro now has a specific target — fix Billing’s hot files — instead of generic “process improvements.”
Or alone

Just Faultlines, on its own

Faultlines doesn’t do DORA, SPACE, or cycle-time tracking. We don’t do people-metrics. If you want sprint-cadence dashboards for executives, you need Swarmia (or LinearB, or DX). Faultlines focuses on the code side: feature map, hotspots, ownership, runtime correlation. The two together answer “how” + “what.” If you only have budget for one and you’re reporting up to leadership, Swarmia is the natural pick; Faultlines is the natural pick when the question is about code rather than people.

Honest take

No vendor pressure

Swarmia and Faultlines don’t compete — they answer adjacent questions. Swarmia answers “how is the team performing?” Faultlines answers “what’s the state of the code they’re working on?” Both inputs feed the same decision: where to invest engineering time. Leader-facing dashboard need → Swarmia. Code-quality + AI-agent context need → Faultlines. Many orgs run both for a complete picture.
