building in public · beta opening soon

Your agent shipped code at 2am.
Did anyone look at it before it went live?

Darkslate is built for the tool your agent writes in an afternoon, not the app your company runs on. Every deploy lands in a private preview first, you get a plain-English summary of what changed, and it only reaches your real domain when you tap approve.

● waiting on you

This push adds a login form to /dashboard and changes how /api/invoices responds. Nobody has seen this build except the agent that wrote it.

  • + New route: /dashboard/login
  • ~ Changed response shape on /api/invoices
  • + 1 new environment variable expected: SESSION_SECRET
Say the quiet part

This isn't for your production app. That's the point.

Darkslate is sized for the internal dashboard, the one-off script, the tool an agent builds while you're getting coffee — not the app your revenue depends on.

Not built for this
  1. Your primary product, at scale
  2. High-traffic, customer-facing apps
  3. Multi-region, high-availability workloads
  4. Anything where downtime costs real money
Exactly built for this
  1. A script an agent wrote to fix one problem
  2. An internal dashboard four people will open
  3. A single-page tool for one specific job
  4. Anything you'd otherwise never bother hosting
The part everyone else gets backwards

Rollback fixes the mistake.
Review prevents it.

Instant rollback is table stakes now — Every self-hosted PaaS has it. It just means the broken build already reached your users before you noticed.

Everywhere else
  1. 1 Agent pushes code
  2. 2 Build passes, traffic switches instantly
  3. 3 A coworker hits the broken login page
  4. 4 Someone notices, or someone complains
  5. 5 You roll back to the last working build
On darkslate
  1. 1 Agent pushes code
  2. 2 Build deploys to a private preview URL
  3. 3 You get a plain-English summary of the change
  4. 4 You tap approve — or send it back untouched
  5. 5 Production only ever runs what you signed off on
What you actually get

Everything a four-user tool needs. Nothing it doesn't.

Deploy review gate

Approve before it's live

Every agent push lands on a shadow URL first. Nothing reaches your domain without a tap from you.

Agent-native

Deploy from the tool you already have open

MCP and a CLI mean Cursor, Claude Code, and Windsurf can ship directly. No dashboard, no manual upload.

Zero-code auth

Nobody writes a login screen again

Magic links and Google sign-in are enforced at the proxy. Your app never sees a password.

Domain rules

"Anyone at the company can view, only you can edit"

Set access like a Google Doc. Change it without touching code or redeploying.

Attached state

Every app gets a database, free

An isolated SQLite or Postgres schema is provisioned the moment your app needs one. No extra bill.

Flat pricing

One bill, not a line item per app

Deploy your 10th internal tool without checking what it costs. You're paying for capacity, not apps.

From the agent's side

This is the whole deploy.

No dashboard click-through, no server to provision. The agent runs one command — you get the approval link.
