Upsun product showcase - What's new in Q3 2025?

Scaling smarter, running faster and building greener: what’s new this quarter on Upsun

We are constantly advancing Upsun to deliver the tools you need. In the past quarter, we've been laser-focused on delivering powerful new features that give you more control, unlock better performance, and streamline your workflows. Our goal is to build tools that not only meet the technical demands of modern applications but also make the development process faster and more intuitive. Our latest AI-assisted features mark a major step forward in our commitment to AI-enhanced development. We’re not adding AI as a gimmick. Every AI capability must deliver measurable improvements in developer efficiency, reliability, or insight. Every feature we ship must prove one thing: it helps developers do their best work.

From intelligent configuration to dedicated resources and sustainability insights, here’s a look at what’s new.

1. AI-generated configuration files: build faster with an AI assistant

Say goodbye to the usual manual scaffolding of your platform setup. With the new AI-Generated Configuration feature from Upsun, you can automatically create your project’s .upsun/config.yaml , based on your code repository. Opt-in to the AI mode when you run upsun init, and the tool will analyze your repository and send it to the Upsun API so the AI can propose a valid starter configuration. While the output is ready to deploy, you still retain full oversight — you review, adjust and fine-tune the YAML as needed. This approach streamlines onboarding for new projects, dramatically reduces setup time, and aligns your configuration with best-practice templates from day one. 

Privacy and security are at the forefront; there is minimal use of personal data: simply reading the user ID for authentication and audit log purposes (the user ID is not sent to AI). Any personal data stored by the customer in their project repository, or logged by the customer's application will be minimized.

2. Upsun MCP Server

Unlock intelligent, AI-driven infrastructure management  simplifying operations, boosting productivity, and integrating seamlessly into developer workflows.

• Natural-language control: Manage infrastructure with plain English commands, no CLI needed.
• Zero context switching: Operate directly from your IDE or AI assistant.
• Secure operations: Respects Upsun’s permissions and access model by default. Defaults to read-only operations unless explicitly configured to allow write operations.
• End-to-end management: Create, monitor, and deploy environments seamlessly across projects
   

Beta Availability
The Upsun MCP Server is currently in beta release. By default, it operates in read-only mode to ensure safety during evaluation. Write operations (such as creating or modifying resources) can be enabled manually via explicit configuration.

3. Guaranteed CPU resources: power when you need it most

For your most critical applications, consistent performance is non-negotiable. We're excited to introduce Guaranteed CPU Resources, giving you access to dedicated, non-shared computing power for your most demanding workloads.

• Why it matters: Guaranteed resources give your application its own dedicated CPU and memory, rather than sharing capacity with other workloads. This ensures consistent, stable performance, especially for workloads like databases, message brokers, or latency-sensitive services that can’t afford slowdowns from “noisy neighbors.” They’re ideal when you need predictable behavior, want to avoid performance surprises, or need to scale a single container beyond the normal shared limits. Once enabled, your app or service runs on a dedicated host just for that container, and the platform automatically provisions more hosts in the background if demand increases. This is entirely self-service, automated, and can be applied per service or app, giving you flexibility and reliability without operational overhead.

4. Automated horizontal scaling: effortless performance, optimized costs

Say goodbye to manual resource management and late-night alerts. Our new Autoscaling feature allows you to automatically and precisely scale the resources for your app containers up or down based on real-time demand. This means no more over-provisioning for anticipated peaks or getting caught off guard by unexpected traffic.

Our goal with this is to make your application’s scaling Simple, Scalable and Sustainable

• Simple - Set up resource thresholds and durations with minimum and maximum instances once and forget about any last-minute manual changes or custom scripts.
• Scalable - Maintain optimal performance during periods of high demand and avoid slowdowns or downtime. Try automated scaling in development or staging environments to make sure your defined thresholds make sense before moving to production.
• Sustainable - Reduce environmental impact and avoid unnecessary costs by automatically reducing resource allocation when demand is low.

For more information on how Autoscaling works, take a look at the documentation.

5. Zero-downtime development: deploy without interruptions

We're really excited to have Zero-downtime deployments in an early-access beta release. The goal is to allow you to keep your applications running smoothly while you release updates. With our new Zero-Downtime Development option, you can choose a deployment strategy that ensures your users never experience interruptions. As this beta feature is still being actively worked on, please take a look at the technical documentation for a deeper dive on how the feature works, current limitations and what use cases work best. We'd love to hear your thoughts and feedback, join our Discord or send us your feedback here

The new ideal workflow: Instead of waiting for a maintenance window or risking momentary outages during deploys, you can now roll out changes seamlessly with no downtime. For those rare cases where platform upgrades require downtime, in the future you'll be able to schedule dedicated maintenance windows on your own terms. The result: uninterrupted service for your users, greater flexibility for your team, and complete confidence every time you push to production.

6. Manual deployment setting: deploy with confidence

We understand that for mission-critical applications, you need an extra layer of control before pushing changes live. The new Manual deployment setting introduces a staging queue, giving your team the final say on exactly when your updates are deployed to production. Add and update variables with changes are staged automatically without triggering a full redeploy. This means you can update sensitive configuration values or environment settings on the fly, bundle them with code changes if needed, and push everything live only when you’re ready; saving time, reducing risk, and keeping your production environment stable.
 

7. Fastly CDN metrics, plugin and alerts.

Managing your CDN shouldn’t require hopping between dashboards or juggling separate tooling. With the new Fastly CDN plugin app, you can configure, monitor, and purge your Fastly CDN directly inside the Upsun console, giving development teams a consistent and consolidated workflow within the tools they already use. This is ideal for teams that deploy frequently across multiple environments and need real-time CDN insight along with quick, precision cache purging. Whether you’re reviewing performance metrics, updating ACL rules, or triggering cache purges, everything is just one click away.

The plugin follows security best practices by storing all credentials locally in your browser and never sharing them with third parties. As an open-source project, our Fastly CDN plugin welcomes community contributions and feedback; view the source code on GitHub and suggest features, join the discussion on the Upsun discord. Or for a more in-depth view of the plugin, check out the dev-center article.
 

8. Carbon emissions dashboard: track your environmental impact

Sustainability is a core value for us and for many of our customers. Our new Carbon emissions dashboard provides clear, actionable transparency into the environmental footprint of your services. You can now view and download your historical emissions data directly from the console, making it easier than ever to track, report, and work toward your company's sustainability goals. This tool empowers you to make informed decisions about your architecture and resource usage with environmental impact in mind.

We want to hear from you!

We’re incredibly excited to see how you leverage these new tools to build, deploy, and scale your applications. Login to your console to try them out today. As always, we welcome your feedback (or checkout our Discord as well!) as we continue to build a platform that works for you.
