Sevalla REST API v3

Sevalla now has a fully featured REST API, giving you programmatic access to everything you can do in the dashboard.

The v3 API covers over 200 endpoints across all major resources - applications, databases, static sites, object storage, load balancers, pipelines, webhooks, projects, and more. Whether you're automating deployments, managing environment variables, or scaling processes, the API has you covered.

Key highlights:

• Full OpenAPI 3.1 specification - Interactive documentation with field-level descriptions, examples, and error responses available at api-docs.sevalla.com.
• Granular API key authentication - Scope each key to specific roles, resources, or actions using the same RBAC system as the dashboard.
• Clean, predictable design - Flat JSON responses, consistent snake_case naming, and proper HTTP methods make integration straightforward.
• Built-in rate limiting - Tiered limits per endpoint type protect your services while giving you plenty of room for automation.
• Error tracking - Every server error includes a unique reference code you can share with support for fast resolution.

The API is designed to work well with CI/CD pipelines, infrastructure-as-code tools, and AI-powered workflows.

Load balancers

Sevalla now supports load balancers, giving you full control over how traffic is distributed across your services.

Load balancers run at Cloudflare's edge network, routing requests close to your users for faster, smarter traffic decisions. You can route to applications, static sites, object storage buckets, external URLs, or even other load balancers - up to 20 destinations per load balancer.

Two balancing modes are available:

• Weighted - Control the proportion of traffic each destination receives. Useful for canary deployments, A/B testing, or gradual migrations between services.
• Geographic - Route users to the nearest destination based on their location, reducing latency for globally distributed setups.

Each destination can be individually enabled or disabled without removing it, and traffic weights are adjustable at any time. Custom domains are fully supported with automatic SSL, alongside an auto-generated Sevalla domain available immediately on creation.

This makes it easier to build resilient, multi-region architectures and manage traffic across services without external tooling.

Projects usage tab

The project page now features a Usage tab, allowing users to track their service costs and consumption during the current billing period and compare them to the previous one.

RBAC-protected Projects

As your infrastructure grows, keeping things organized and secure is essential. You can now group your services into Projects within your company workspace.

To give you more control over who can access what, we're also rolling out a new Project Developer role. This allows you to grant fine-grained, project-level permissions to your team members. A Project Developer can fully manage the services within their specific project, but they are completely restricted from seeing or touching resources outside of it.

This makes it simpler to onboard new developers and restrict access without slowing down their workflow.g

Granular API key permissions

API keys on Sevalla now support fine-grained permission control, giving you full flexibility over what each key can access and do.

You can assign one of the predefined roles - Company Admin, Company Developer, Company Billing, or Company Viewer - or build a custom permission set tailored to your exact needs. Custom permissions let you select specific actions per resource type and scope them down to individual resources.

For example, you can create an API key that only has view access to a single application, or one that can manage databases but nothing else.

This makes it easier to follow the principle of least privilege across your integrations, CI/CD pipelines, and team workflows.
