The Ultimate Open Source
Headless CMS for SvelteKit
The ultimate backend dashboard combining the best features from leading Headless CMS platforms.
Why Choose SveltyCMS?
Developer-First Mindset
SveltyCMS is built by developers, for developers. By using **SvelteKit + Svelte 5** as our core, we offer one of the fastest ways to build and deploy applications with modern tooling like Vite 8 and ParaglideJS (compiled, zero-runtime i18n).
Privacy-First AI (Ollama)
Local inference via Ollama (vision model `llava`) for automatic image tagging, AIEnrichment (summarization/SEO), and smart navigation via the AI Command Bar.
Production-Ready Adapters
Choose your engine: MongoDB, PostgreSQL (GIN indexes), MariaDB (TTL cleanup), or SQLite (7 performance PRAGMAs). All production-ready with engine-specific optimizations.
Open Source, Free for Almost Everyone
No hidden fees, no 'Enterprise-only' features. Multi-tenancy and SSO are available to everyone. Licensed under BSL 1.1: free production use for organizations under $1M in annual finances, free for development and testing, GPLv3 after three years — large enterprises support development through a commercial license.
Enterprise Performance Benchmarks
Auth Latency: <1ms (3-layer cache) | REST Dispatcher: 14,000+ RPS | Cold Start: <1s | Unit Tests: 732/732 Passing
SveltyCMS is designed for developers who want the flexibility of a headless architecture. With **71% middleware overhead reduction** (12 µs p95), **14,000+ REST RPS**, and the **VoidZero Rust toolchain** (47ms linting, sub-18s production builds), we provide one of the fastest headless CMS experiences available based on published benchmarks.
Whether you are building a personal blog or a complex SaaS with **Multi-Tenancy 2.0**, SveltyCMS ensures quality with **732/732 passing tests**. Our production-ready adapters use cross-adapter prepared statements (0.007ms SQLite reads), single-trip mutations (40% latency reduction), and Bloom-filter negative caching (100,150x miss speedup).
