Engineering capacity

Effective engineers behind Cloudflare, against its pre-AI baseline. Each subject has its own: Cloudflare's is 0.42 ETV / dev / mo, its first reading in April 2025. Per-engineer ETV divided by that gives a capacity multiple, and that multiple applied to the engineers active in the trailing 90 days turns it into engineer-equivalents. The line is the real headcount, so the gap between line and area is what the leverage is worth. Because each baseline is its own, every subject opens at 1.0x on its first day: multiples measure improvement and are not comparable between subjects.

Cloudflare vs. 500 OSS Performance Index

Per-engineer ETV for Cloudflare against the pooled 500 OSS Performance Index. Both lines are 90-day rolling averages scaled to a 30-day month, so they share one axis and can be read against each other at any point. Pick a window to zoom the chart to it. Latest reading: Cloudflare is 62% below the index (1.22 vs 3.22 ETV/dev/mo). At the start of the tracked period the gap was 54% below.

Behind the numbers

Aug

Written summary of the work completed each month.

Delivery remained steady and in line with the recent run rate during 2026-08 across 511 commits, characterized by heavy investments in testing infrastructure and automated schema maintenance. Candidate-material shifts compared to the 5-month average included a +71% increase in Tests score (44 vs 25 average), alongside decreases in Features (-41%) and Fixes (-52%). Key accomplishments included the rollout of durable job queues in the lifecycle subsystem and extensive test suite modularization for webstreams.

Highlights

Observations

  • Tests score rose +71% compared to the 5-month average (44 vs 25 average), driven primarily by test refactoring and coverage expansion across the webstreams subsystem
  • Features score decreased 41% compared to the 5-month average (19 vs 33 average), as commit activity centered largely on schema updates and testing harnesses
  • Fixes score dropped 52% compared to the 5-month average (8 vs 17 average), reflecting lower recorded rework across runtime components
  • Commit volume reached 511 commits vs the 373-commit 5-month average (+37%), largely inflated by automated OpenAPI schema synchronizations and routine daily release bumps like 8865ba50 (Workers) and e9dda596 (Workers)
  • Streams API testing underwent significant architectural cleanup, absorbing legacy monolithic files like streams-test.js into isolated test suites in 65d10471 (James) and ffae63f9 (James)

Repositories

Where each repository stands: average performance per engineer per month over the last 90 days, with the rolling 90-day curve behind it. The range picks the window (past 90d): it sets how much of the curve you see, the Δ across it, and the span the work mix is measured over. Ranked highest first.

Performance Composition

Each month's output split by type of work: Features (new value), Maintenance (sustaining systems), Tests, Docs, and Fixes (rework). The yellow line is output per engineer, so when it rises each engineer is delivering more, whatever the team size did. Unit: Engineering Throughput Value (ETV).

Cost per Performance Unit

−66%

If performance per engineer more than doubled, each unit of engineering performance now costs approximately 66% less than at the baseline 90-day window (ending 2025-04-01). Treat this as a direction, not a price: the exact figure depends on fully-loaded engineer cost, but which way it moved is not in doubt.

Effective Capacity Added

+199 engineers

At today's productivity, the current 104-person team delivers the performance equivalent of 303 engineers at the baseline 90-day rolling window (ending 2025-04-01). That's roughly 199 engineers worth of capacity added through productivity gains, not hiring.

CapEx vs OpEx

Each month's work split two ways. CapEx (capitalizable investment) is the work that builds the asset: Features, plus the Tests that prove it works and the Docs that explain it. OpEx (operating expense) is keeping it running: Maintenance and Fixes. The yellow line is the CapEx share, so a rising line means more of the month went into building new rather than sustaining what exists. Unit: Engineering Throughput Value (ETV).

Hours per Repository

Trailing 90-day window (64 working days). Org-level capacity is allocated to each repo by its share of org performance, then split CapEx / OpEx by that repo's own Features + Tests + Docs vs Maintenance + Fixes mix.

Feature Contribution

Who shipped each month's new feature work, as a share of that month's total. Bands of similar width mean new value is coming from across the team; one band that stays wide means most of it rests on the same person. Named engineers shipped the most Features over the period. Everyone else is grouped as Others.

Quarterly Summary

Engineers and the Features / Maintenance / Tests / Docs / Fixes mix for each quarter. Cost / Perf Unit is what one unit of performance costs against Q2'25. Eff. Capacity Added is measured against this org's own pre-AI baseline instead, its first reading in the index, so it agrees with the capacity tile and chart above.
