Platform.sh is now Upsun

Over the last decade, Platform.sh has grown into a leading cloud application platform trusted by developers and organizations globally. Our mission has remained constant: to inspire forward-thinking teams to build, iterate, and scale applications without the burden of managing infrastructure.

In recent years, application development has become both more complex and more efficient. AI is transforming the speed and efficiency with which applications are built. Today's developers are creating software 55% faster with AI-powered tools, while others are scaling globally and juggling multiple types of workloads that we haven't seen in decades. This means application volume is set to surge as development cycles compress from months to weeks, or even days, and the complexity of building has shifted from application coding itself to the tooling management, cloud deployment, securing, and scaling the application in a way that is sustainable, maintainable, and cost-efficient.

Our ambition is to push the boundaries of cloud and developer experience even further to align with this revolution. Today, we are excited to announce the next chapter in that journey; Platform.sh is evolving and will become Upsun. While our mission remains unchanged, we are expanding our commitment to supporting the growing and complex needs of organizations like yours.

Why the name Upsun?

"Up" represents the fundamentals we have consistently delivered: uptime, reliability, and moving upwards to meet new challenges. 

"Sun" hints at our global footprint and aspiration to be the dawn of what's coming next in application development. By definition, "upsun" means the hours between sunrise and sunset, your productive hours. We operate globally, following the sun to provide 24/7 support.

While Platform.sh established our foundation in developer-focused hosting, Upsun embodies our evolution into the cloud application platform that humans and robots love. We support everything from traditional web applications to AI-powered services, complex microservices architectures, MCP servers, and technologies that diverse teams are building today.

What stays the same?

Practically everything you have come to rely on will remain at the core of Upsun.  For existing Platform.sh customers, here's what this means:

• Your applications and workflows continue to run exactly as they have 
• The support team you already know and trust continues without interruption
• Your current pricing plan stays the same
• Your projects, workflows, and integrations remain untouched
• Your account, billing, and contract terms are unchanged

What's new and better?

AI-ready by design

As AI transforms how applications are built, Upsun is built for teams where humans and AI work together. Onboarding is faster with AI-generated configuration that handles your project setup. Upsun also integrates directly with Claude Code and GitHub Copilot through our MCP server and API, and provides the infrastructure you need to deploy LangChain applications,  custom AI agents, and modern data-driven apps.

Predictable and more granular pricing

While the current pricing plan remains available, now you have additional pricing options! We're introducing Upsun Flex, a predictable and transparent pricing model that allows you to pay only for the resources you provision. For example, if your app is set to use 1GB RAM and 0.5 CPU cores, you pay for exactly that. When Black Friday traffic spikes, scaling you up to 4GB RAM and 2 CPU cores for those crucial hours; you pay for those extra resources only during this period; then costs drop back to your baseline. Your costs scale linearly with your actual resource consumption, which means your infrastructure spending finally moves in sync with your business activity.

Preview environments

Spin up a complete production-grade clone of any branch in minutes. Every git push creates an environment replica that mirrors your production setup, including configuration, code, data structure, and file handling, all defined through a single configuration file. Test your UI, backend, and AI components together with realistic data before going live. 

Multi-cloud flexibility

Deploy on any primary cloud provider, anywhere in the world. Upsun supports a range of cloud providers, including AWS, Azure, Google Cloud, IBM, and OVHcloud. Additionally, you can switch regions by modifying a single line in your configuration. Now you can run your API on AWS while keeping ML workloads on Google Cloud. 

Enterprise-grade security

We have achieved several independently audited industry certifications from the outset, which demonstrate that your data is handled with appropriate care and in accordance with industry standards. Platform.sh has maintained SOC 2 Type 2 and PCI DSS Level 1 compliance, along with advanced security controls and audit trails.

 Now, with Upsun, we still have all certifications previously available with Platform.sh, but we have also added ISO 27001, FS Cloud certification, and IBM Cloud region availability, and have received Gartner reports.

Environmental responsibility + green hosting incentive

High performance shouldn't come at the expense of the planet. Upsun delivers up to 12 times more efficient CPU usage and up to 15 times lower emissions in low-carbon regions, with real-time CO₂ tracking integrated directly into your billing console. With our new green hosting incentive, you can deploy in eco-friendly areas and receive a 3% discount on resource usage.

The bigger picture

This evolution reflects the direction in which software development is heading. Teams are building more complex and diverse applications than ever before. AI is transforming how we code and what we build and organizations need infrastructure that can adapt to new requirements rather than constrain what's possible. We believe technology will change the world for the better, and we're committed to helping development teams focus on what matters most: building applications that matter.

Traditional platforms require you to fit your vision into their boxes. Upsun adapts to your applications, from running PHP alongside Python AI agents to scaling across multiple cloud providers to spinning up environments that mirror complex production setups. The platform grows with your technical requirements.

And now you have pricing options that match this flexibility. Whether you're building content applications, e-commerce platforms, or integrating AI-powered features, Upsun provides the foundation that scales with your ambitions.

What happens next?

The transition to Upsun is completely seamless. We're handling everything behind the scenes, so your applications continue to run without interruption. Platform.sh is getting a new name and expanded capabilities, but the reliable platform and team you trust remain stronger than ever.

You are at the heart of this evolution, and we are immensely excited to embark on this new chapter with you. 

A brighter future is upon us. Welcome to Upsun.
