Ranking — sorted by GrowthFriction Score
GitHub
Fleet championGrowthFriction Score
51.84
developer collaboration (Microsoft-owned) · founded 2008 · confidence 0.8
GitHub is the developer-fleet champion. AUG composite ~52, fleet-champion tier. The framework predicts this — open-source ecosystem + workflow lock-in + Microsoft distribution compound multiplicatively across every factor. The Monetization gap (8) reflects the historic free-first strategy; Copilot AI + Enterprise tiers are the active corrections. The lesson for founders: a free product that compounds via network effects can outscore most paid SaaS for 15+ years before monetization needs to catch up.

Cloudflare
ThrivingGrowthFriction Score
45.36
edge network + infrastructure (B2B + indie) · founded 2009 · confidence 0.8
Cloudflare is one of the great freemium-compound SaaS plays in history. AUG composite ~45, fleet-champion tier. The free tier serves as both moat (developer affinity) AND distribution (every site they're on shows "powered by Cloudflare"). Lesson: free tier that solves a real problem at zero marginal cost = strongest possible Acquisition engine. Cloudflare's margins on the free tier are net-negative on infrastructure but net-positive on Acquisition CAC across the funnel.

Resend
ThrivingGrowthFriction Score
41.47
email API (developer infrastructure) · founded 2022 · confidence 0.8
Resend is the new-developer-default for email API in 2024-2026. AUG composite ~35, Thriving tier. The React Email open-source play is the asymmetric Advocacy lever — devs find Resend via React Email tutorials. Lesson for founders: ship an open-source companion product that pulls developers into your paid SaaS. React Email itself doesn't monetize directly; it monetizes through the funnel back to Resend.

Supabase
ThrivingGrowthFriction Score
36.74
backend-as-a-service (open-source developer infra) · founded 2020 · confidence 0.8
Supabase is the indie-developer-default backend-as-a-service. AUG composite ~50, Fleet-champion tier. The open-source + Postgres + multi-product + edge functions combo compounds across every factor. Lesson for founders: when you can ship MULTIPLE products that share infrastructure (auth + DB + storage + realtime + functions), the compound is multiplicative. Pick a category where you can credibly ship 4-5 products around one core.

Vercel
ThrivingGrowthFriction Score
36.74
deployment platform (developer infrastructure) · founded 2015 · confidence 0.8
Vercel demonstrates the framework-platform play. AUG composite ~31, fleet-champion tier. The Next.js compound is the asymmetric advantage. Monetization weakness is solvable via pricing predictability — they've experimented with this but the pattern continues. Lesson: own the framework, win the platform. The downstream business catches every dev using your upstream open-source.

PostHog
ThrivingGrowthFriction Score
33.18
product analytics (open-source B2B SaaS) · founded 2020 · confidence 0.8
PostHog is the open-source product-analytics insurgent. AUG composite ~33, Thriving tier. The combination of OSS + multi-product (analytics + flags + replay + experiments) + transparent radical content is rare. Lesson for founders: open-source is a real Advocacy multiplier if you commit fully (handbook public, roadmap public, pricing public, even salaries public). Half-measures (closed-core OSS) don't compound the same way.

GitLab
Needs focusGrowthFriction Score
14.05
developer collaboration (independent) · founded 2011 · confidence 0.8
GitLab is the GitHub alternative. AUG composite ~14, healthy tier. The structural disadvantage vs GitHub (post-Microsoft) is mindshare and default-choice; GitLab's wins are self-hosted/enterprise-data-sovereignty cases. AUG framework correctly shows the 38-point composite gap between #1 (GitHub) and #2 (GitLab) in this category — being the deliberate alternative caps your ceiling. The lesson: alternatives can build durable healthy-tier businesses by going deep in their differentiation (here: self-hosted + transparent culture), not by trying to beat #1 on its strongest factors.

Methodology + confidence
Every audit is external-observation — scored from publicly visible signals only. Composite formula: AUG = 100 × Acq × Act × Eng × Ret × Adv × Mon × Perf ÷ 10⁷ — multiplicative, so a zero in any factor near-zeros the whole. See full scoring transparency.
