Key Players
Competitive Landscape
Most companies pick a headless CMS supplier only after a trial that tests content structure, ease of editing and API speed under load. Purchasing teams also weigh hosting regions, single sign-on and audit logs, so enterprise plans carry most of the value in each contract. A successful trial usually spreads brand by brand, which makes the first project decisive for long-term share.
Across the category, competition runs on three fronts. Suites compete on bundled analytics, commerce and CRM links. API-first vendors compete on ease for developers and speed, and open-source projects on control and cost. Adjacent categories grow more slowly, as the digital experience platform market is projected to grow at a 6.5% CAGR from 2026 to 2036, well below the pace of headless tools.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| September 2026: Salesforce completes the Contentful acquisition. | Demand for CRM-linked content. | Suite consolidation. | Agent-ready content for CRM users. |
| June 2026: Contentstack launches Agent OS. | AI agents in marketing. | Agentic content platforms. | Automated personalisation projects. |
| November 2025: Adobe agrees to buy Semrush. | Visibility in AI search. | Suites adding optimisation tools. | Bundled content and search offers. |
Together, these moves point toward content platforms that serve both people and software agents. Suppliers with clean content models and open APIs will gain share as buyers consolidate tools through 2036.
Who leads the headless CMS software market?
Contentful, now inside Salesforce, holds the strongest position among API-first vendors, with more than 4,800 brands on the platform. Adobe and Sitecore lead among suites, given large installed bases in enterprise marketing teams.
Which companies have documented positions?
Contentful, Contentstack, Sanity and Adobe hold clear positions, with recent deals, launches and funding rounds that show active investment in content platforms. Storyblok, Hygraph and Strapi hold strong positions with developer-led teams.
What should buyers evaluate before approving a supplier?
Buyers test content structure, API limits, ease of editing and language features in a trial. Hosting regions, security certifications and exit terms for content export also decide approval, since content outlives any single front end.
How is competition expected to change through 2036?
Suites and CRM vendors will absorb more API-first platforms, and independent vendors will compete on openness and AI agent support. Open-source tools will keep a strong position among cost-sensitive and self-hosting buyers.
