Platform Atlas
158 systems worth building on.
A curated, evidence-backed map of SaaS platforms across customer, marketing, content, media, analytics, commerce, collaboration, data, and interface infrastructure.
Not a ranking. Platforms are included because they own consequential operating state, expose meaningful capabilities, or demonstrate a distinct BYO-UI pattern. Maturity is an architectural assessment, not a procurement recommendation.
Conservative evidence facets. Surface, action, and availability filters match explicit terms and links in the dated publication record. An absent facet is not proof that a capability is absent. MCP writes are classified only from MCP write evidence—not from broader API actions.
