01 / Collections
Database tables on demand
Define a collection via API and unilayer creates the real PostgreSQL table at runtime. Filtering, sorting, paging, field selection, unique indices and relations included.

Stop rebuilding the backend.
Ship the product.
unilayer puts your data, files and users behind one secure API. Create database tables at runtime, store and transform assets, manage permissions – over REST or GraphQL, on your own infrastructure.
Every new project starts with the same three months of plumbing.
- Schema & CRUDMigrations, endpoints, validation, paging, filters – for every single table.
- FilesUploads, storage backends, thumbnails, versioning, checksums.
- Access controlUsers, tokens, roles, fine-grained permissions – and getting them right.
The solution
Three building blocks. One layer. Zero boilerplate.
02 / Assets
Files, versioned & transformed
Upload once, store locally or on S3/MinIO. SHA-256 checksums, versioning, soft-delete – plus on-the-fly image resizing and WebP conversion via URL parameters.
03 / Users
Permissions that scale
Users, roles and policies managed through the API. Permissions down to a single collection, e.g. collections:shop:orders:read.
Developer experience
Write a C# class. Get a backend.
The typed .NET client maps your models to collections, syncs the schema and speaks LINQ. Not on .NET? Every collection is instantly available over REST and an auto-generated GraphQL schema.
- ✓LINQ queries translated to server-side filters
- ✓Client-side field encryption with AES-256-GCM – the server only sees ciphertext
- ✓Schema versioning & migrations built into the client
- ✓OpenAPI docs and GraphQL explorer out of the box
// 1. Describe your data
[UniCollection("customers")]
public class Customer
{
[UniField("email", IsUnique = true)]
public string Email { get; set; }
[UniField("iban", IsEncrypted = true)]
public string Iban { get; set; }
[UniField("revenue")]
public decimal Revenue { get; set; }
}
// 2. Use it
await client.SyncCollectionSchemaAsync<Customer>();
var vips = await client.Query<Customer>()
.Where(c => c.Revenue > 10000)
.OrderBy(c => c.Email)
.ToListAsync();Production-ready
Built for the day it really matters.
High availability
Cluster mode with Raft leader election. Writes replicate to every node, reads stay local, failover is automatic.
Secure by default
Mandatory TLS and node-to-node mutual TLS, hashed tokens, rate limiting and a least-privilege permission model.
Audit trail
Every schema change is recorded in a system history – exportable, importable, traceable.
Fast
Valkey caching with automatic invalidation on writes. Health checks for database, cache and storage.
Why unilayer
Your infrastructure. Your data. Your rules.
SaaS backends are fast to start and hard to leave. unilayer gives you the same speed, but it is open source and runs wherever you want – on-prem, in your cloud, in a single container. No vendor lock-in, no data leaving your network, no per-request pricing surprises. And if we ever disappear, your backend keeps running.
