The Rise of Open-Source API Platforms for Secure On-Premises Control
1. On-premises deployment holds 29.8% of API management market share
Despite cloud dominance, on-premises deployment maintains nearly a third of the market—reflecting sustained enterprise demand for data sovereignty. DreamFactory operates exclusively as self-hosted software, supporting on-premises, customer-managed clouds, and air-gapped environments where data control is non-negotiable.
2. Cloud computing adoption continues to accelerate across enterprises
While cloud adoption grows rapidly, enterprises in regulated industries—finance, healthcare, government—require alternatives that provide greater control. Open-source platforms that support both cloud and on-premises deployment provide the flexibility these organizations need.
3. 34% implemented public cloud comprehensively; 51% use it selectively
A U.S. survey reveals that only 34% committed fully to public cloud, while 51% deploy cloud services selectively. This hybrid reality demands API platforms that function identically across deployment models—a core strength of self-hosted solutions like DreamFactory.

Open-Source API Generator Stats: Speeding Up Enterprise Integration
10. 82% of organizations have adopted some level of API-first approach
The API-first movement has reached critical mass, with organizations designing around APIs before building applications. DreamFactory's automatic API generation accelerates this approach by eliminating the coding bottleneck.
11. 25% operate as fully API-first organizations (12% increase from 2024)
This 12% year-over-year increase in fully API-first organizations demonstrates accelerating commitment to API-centric architecture. Configuration-driven platforms enable smaller teams to achieve this maturity faster than manual development allows.
12. 93% of respondents use REST APIs as their primary standard
Despite GraphQL and gRPC alternatives, REST remains dominant at 93% adoption. This validates investment in REST API generation platforms that produce standardized, widely-compatible endpoints.
13. 69% of developers spend more than 10 hours per week on API-related tasks
The developer time investment in API work represents significant opportunity cost. Auto-generated APIs reclaim these hours for higher-value development activities.
14. 75% of organizations use CI/CD pipelines for API deployment
The CI/CD adoption rate confirms enterprise commitment to automated deployment. DreamFactory's Kubernetes and Docker support integrates with existing deployment pipelines.
The Role of Open-Source in Advanced API Security & Access Control
15. 51% of developers worry about unauthorized API calls from AI agents
Security concerns around AI integration are significant, with 51% citing unauthorized access as a primary worry. DreamFactory's enterprise security controls include granular role-based access control, rate limiting, and comprehensive audit logging to address these concerns.
16. 49% are concerned about AI systems accessing sensitive data
Nearly half of developers fear inappropriate AI access. Platform-enforced security with field-level permissions ensures AI integrations only access authorized data—a capability built into DreamFactory's security layer.
17. 93% of API teams face collaboration blockers
Documentation inconsistency affects 93% of teams, creating security risks when teams work with outdated specifications. DreamFactory's auto-documentation generates live Swagger/OpenAPI specs that remain permanently synchronized with actual API behavior.
18. 17% use no monitoring tools at all for their APIs
The absence of monitoring in 17% of organizations creates blind spots for security incidents. Built-in audit logging in auto-generated API platforms provides baseline visibility without additional tooling.
19. 67% conduct functional testing; 67% conduct integration testing
While 67% perform both testing types, consistency varies with manual API development. Auto-generated APIs produce predictable, testable endpoints that simplify quality assurance.
Beyond REST: Open-Source API Platforms and Legacy System Modernization
20. API usage continues to grow as enterprises expand digital operations
The sustained growth outlook confirms APIs as permanent enterprise infrastructure. Legacy systems require API layers to participate in modern architectures—a primary use case for DreamFactory's SOAP-to-REST conversion capabilities.
21. Data integration remains critical to enterprise success
When business leaders identify integration as critical, legacy systems without API access become competitive liabilities. Vermont DOT connected 1970s-era systems to modern databases using DreamFactory's REST APIs without replacing core infrastructure.
22. Enterprises increasingly build integration capabilities in-house
The preference for in-house integration reflects control requirements. Self-hosted API platforms support this approach while eliminating the custom coding burden.
