By the numbers

A quantitative snapshot of the supabase/supabase monorepo. Data collected on 2026-04-30 at commit d1ec069783 on master.

Size

The repo is large by every dimension — long-lived, broad surface area, many contributors.

Metric	Value
Working tree size (incl. .git)	~3.1 GB
TS / TSX source files (under apps/ + packages/)	~5,962
*.test.ts(x) test files (under apps/ + packages/)	~340
MDX content files (under apps/)	~1,461
Total commits (master)	~35,937
Distinct authors over project lifetime	~1,917
First commit	2019-10-12 ("Init monorepo")
Most recent commit (HEAD)	2026-04-29

The numbers above include Studio (apps/studio) which is by far the largest single app — its components/interfaces/ directory alone has ~48 feature folders and data/ hosts ~92 React-Query domain modules.

Activity

The pace has accelerated steadily. Monthly commit counts (approximate) for recent months:

Month	Commits
2025-09	~396
2025-10	~447
2025-11	~444
2025-12	~386

The single highest-churn area in the working tree is apps/studio/components/interfaces/ — most product features ship as a folder there.

Bot-attributed commits

The repo has only a small number of merge commits with bot co-authorship in the surveyed window (e.g. Co-authored-by: ... [bot]). This is a lower bound on AI-assisted work, since inline AI tools (Copilot, Cursor) leave no git trace. The repo is currently human-driven in git log.

Breadth

Surface	Count
Apps	7 (studio, docs, www, design-system, ui-library, learn, lite-studio)
Top-level workspace packages	17 (ui, ui-patterns, common, ai-commands, pg-meta, api-types, shared-data, icons, marketing, config, tsconfig, eslint-config-supabase, dev-tools, build-icons, generator, pg-meta-cli, mcp-utils-build and similar)
Studio data-domain folders (apps/studio/data/)	~92
Studio interface feature folders (apps/studio/components/interfaces/)	~48
GitHub Actions workflows (.github/workflows/)	~46
Docker Compose services in docker/docker-compose.yml	13+ runtime services
Docs guides sections (apps/docs/app/guides/)	21

Complexity

The largest concentration of complexity is in Studio. Notable hotspots:

• packages/common/telemetry-constants.ts (~85 KB) — every product event constant in one file. The single largest TS source in the workspace.
• apps/studio/components/interfaces/Auth/, Database/, Storage/, SQLEditor/, TableGridEditor/ — each ranks as the most-edited area in its quarter.
• apps/www/components/ has ~43 sub-folders for marketing UI primitives.

Inline pointers

Per-subsystem stats appear on the relevant pages:

• Studio surface area: apps/studio
• Self-host bundle: deployment
• Shared UI: packages/ui
