Synapse is a headless CMS that runs on your server — no SaaS dependency, no monthly fee, full control over content, roles, and spaces. Built for agencies and businesses that take ownership seriously.
Features
Process
No weeks of setup. We deploy Synapse on your server and you're productive within 24 hours.
We discuss your content structure — what collections you need, which fields, how they relate. Synapse is deployed on your Hetzner server and you get access to your instance the same day.
Your content model is configured to match your requirements — field types, locales, relations, permissions. We set up spaces if you're managing multiple clients and configure roles for your team.
Frontend connected via API, first content imported, webhooks configured for automated deployments. You take control — with full documentation and direct support during the transition.
Deep Dive
001
Overview
Synapse was built to make daily content work faster, clearer, and more independent — without the complexity of enterprise platforms.
Run multiple projects or clients from one instance — with complete data isolation.
All assets centrally managed with public links, metadata, and drag-and-drop upload.
Full REST API with filtering, sorting, population of relations, and field projection.
Every field can be localized — switch between languages in the editor, query by locale via API.
Trigger external systems on publish, update, or delete — automated deployments, cache clearing, notifications.
Draft, review, schedule, publish — content goes live when it's ready, not when someone clicks too fast.
Full version history per entry — compare, review, and restore any previous state.
See who's editing what — live presence indicators and entry locking prevent conflicts.
Comparison
You're either paying monthly for a system you don't own, or fighting a monolith that breaks with every update. Here's option three.
| Feature | Synapse CMSBest fit | Synapse CMS | WordPress |
|---|---|---|---|
| Monthly cost | One-time — no subscription | Free core, but plugins cost monthly | From 300 €/month |
| Data control | Your server, your country, your rules | Self-hosted possible, but messy | SaaS only — no self-hosting |
| Custom fields | Unlimited — define any structure | Via ACF plugin — extra dependency | Yes, but limited in free plan |
| Multi-tenancy | Built-in — Spaces with full isolation | Multisite — fragile, shared DB | Separate environments — extra cost |
| API quality | REST with filter, sort, populate, projection | REST exists, inconsistent | GraphQL — powerful but complex |
| Vendor lock-in | None — you own the code | Low but plugin-dependent | High — proprietary platform |
