Queue as a service
A fair waiting room
for any launch.
Sorted absorbs the traffic spike, keeps every visitor updated on their place in line, releases them at your pace, and hands your app a signed token proving they waited their turn — no backend changes required.
Works with any website. Set up in under five minutes.
Flash sales, ticket drops, launches
When everyone
arrives at once.
Without a queue, every request hits your server at the same moment and it fails. With Sorted, visitors wait in arrival order and enter at your pace.

Keep this page open. You'll go to the site automatically when it's your turn.
Three steps to a surge-proof site.
Create the queue, point visitors at it, and verify each release token before they reach your app.
01 / Create a queue
Set your target URL, release rate, and token TTL via the dashboard or API. Customize the waiting room with your own content.
POST /api/queues
{ "queue_event": {
"title": "Flash Sale",
"target_url": "https://shop.com/sale",
"release_rate": 200,
"token_ttl_minutes": 15
} }
02 / Redirect or embed
Point visitors at sorted.fast/queue/42,
or embed the waiting room with
<iframe src=".../queue/42/embed">
— no changes to your backend needed.
03 / Verify tokens
Released visitors arrive at your site with a signed token. One API call confirms they waited their turn.
POST /api/queues/verify_token
{ "token": "eyJhbG..." }
→ { "valid": true,
"visitor_id": "v_abc",
"queue_event_id": 42 }
Plug into what you already run.
A / DNS redirect
Send launch traffic to the queue first. Released visitors return with a signed token.
sale.shop.com → CNAME sorted.fast → /queue/42 → shop.com/sale?token=...
B / Iframe embed
Keep visitors on your page. The waiting room runs inside it.
<iframe
src="sorted.fast
/queue/42/embed"
width="100%"
height="500">
</iframe>
C / API only
Build your own waiting screen. Join, poll position and verify through REST.
POST /api/queues/:id/join GET /api/queues/:id/status/:v POST /api/queues/verify_token
Why a queue helps
Every request at once, or one at a time.
Without a queue
Every request hits your server at once — it buckles.
With Sorted queue
Visitors wait in a fair queue — released at your pace.
Architecture
Built on telecom-grade infrastructure.
Each queue runs as an isolated process with its own in-memory state — no shared database locks, no single point of failure. The same runtime that handles a large share of the world's phone calls.
- ETS hot path — zero bottleneck on join
- Fair FIFO ordering with microsecond timestamps
- Real-time position updates over WebSocket PubSub
- Cryptographically signed release tokens
Everything you need.
Customizable waiting room
Add your own content — pricing, FAQs, promotions. Keep visitors engaged while they wait.
Configurable release rate
Control exactly how many visitors per minute reach your site. Protect your infrastructure from overload.
Embeddable widget
Drop the waiting room into your own page as an iframe, or use the standalone URL. Works either way.
Real-time position updates
Visitors see their exact position and estimated wait, updating live over WebSocket.
Signed access tokens
Released visitors get a cryptographically signed token with configurable TTL. One call to verify.
Full REST API
Create queues, check status, verify tokens — all via API. Perfect for automation and agents.
Built for any surge.
