Is it for you?

This service is ideal if you're in one of these situations

⚠️

Your infra doesn't scale

Every traffic spike is a problem. Servers go down, costs blow up, and the team is constantly firefighting.

💰

Infra costs out of control

You pay for servers 24/7 even when you're not using them. You don't know how to optimize resources. The cloud bill goes up every month with no control.

🐌

Slow, risky deploys

Every deploy is an event. It requires planning, maintenance windows and praying nothing breaks in production.

🏗️

Legacy monolith

You have a legacy monolith that works but holds you back. You want to migrate to cloud-native without rewriting everything from scratch.
