The authorization thesis

Authorization is complex.
Managing it shouldn't be.

Every home-grown auth layer starts as a few if‑statements and grows into an unstable tower of edge cases. AuthZed replaces that risk with one declarative check, backed by a system that scales to any level of demand.

Before·Today, without AuthZed

function canEditDocument(user, doc) {
  if (!user.isActive) return false;
  if (doc.orgId !== user.orgId) return false;
  if (doc.ownerId === user.id) return true;
  if (doc.classification === 'confidential' && !user.hasMFA) return false;
  if (doc.legalHold) return false;
  return false;
}

function canShareDocument(user, doc) {
  if (doc.teams.some(t => user.teams.includes(t))) return true;
  if (doc.sharedWith.length > 100 && !user.isEnterprise) return false;
  return false;
}

After·With AuthZed

const allowed = await spicedb.checkPermission({
  resource: { objectType: 'document', objectId: doc.id },
  permission: 'edit',
  subject: { objectType: 'user', objectId: user.id },
});

Scale

Tens of billions

of checks daily across production codebases

The whole integration

Three API calls. That's it.

From zero to live permission checks in under 10 minutes. No authorization code to write, no infrastructure to manage.

The platform

One Platform,
Three Pillars

One platform for every permission check across your stack: user access, agent tool calls, per-document RAG.

Tens of billions of checks every day across the systems you can't afford to get wrong.

01
One centralized permission system
for your entire application and AI ecosystem
02
One system of record
for access control and audit logging
03
One self-service authorization platform
that you can run like your cloud infrastructure

Why teams switch

A flexible authorization system

Build, deploy, and scale authorization without running the database.

Eliminate Engineering Overhead

No more homegrown authorization stacks.

Scale Effortlessly

Infrastructure-layer permissions that grow with your app.

Built for AI agents

Tool-level checks for agents, per-document access for RAG, fine-grained scopes for MCP.

Every language you ship in

REST, gRPC, and SDKs for Go, TypeScript, Python, and more.

Pay-as-you-Grow Pricing

Hourly metered billing with monthly invoicing in arrears.

Trusted by Leading Platform Teams

Workday, Turo, Neo Financial, and more.

We love Authzed—it makes evolving our permissions model effortless, with a powerful schema language, makes rapid prototyping possible along with rock-solid production performance, all without heavy maintenance.
Authzed Cloud delivers the power and reliability of Dedicated at a startup-friendly price, without the hassle of running SpiceDB. That lets me focus on building our modern docs platform, confident our authorization is secure, fast, and future-proof.
