What’s new in Upsun: Q4 2025

Here at Upsun we've continued to focus on some of the core pillars that make us the platform that humans and robots love: stronger governance, predictable performance, operational efficiency, and platforms that scale with confidence. More control with less overhead.

App‑specific environment variables

Managing configuration across large, multi‑application projects can quickly become a source of risk and operational drag. App‑specific environment variables introduce a cleaner, safer model by allowing variables to be defined per application instead of globally.

• Improved security posture: Sensitive values like API keys or credentials are accessible only to the application that requires them, reducing blast radius.
• Reduced operational churn: Changes affect only the relevant application, cutting down unnecessary rebuilds and redeployments.
• Better isolation at scale: Teams can reuse variable names across applications while maintaining clear separation of concerns.

This feature is particularly valuable for organizations running complex, multi‑service architectures where governance and change control are critical. For more information, check out the documentation.
 

Composable images

Composable images give teams full declarative control over application runtimes—without introducing the complexity of managing custom containers manually.

With composable images, you define exactly which runtimes, versions, binaries, and extensions your application needs. Upsun takes care of building a reproducible, production‑ready image that behaves consistently from development through production.

• Standardization without rigidity: Support multiple runtimes or niche dependencies while maintaining platform consistency.
• Lower operational risk: Reproducible builds ensure what runs in production matches what was tested.
• Future‑proof flexibility: Avoid platform lock‑in caused by fixed runtime assumptions.

This approach balances developer autonomy with the predictability IT organizations require. For more information, check out the documentation.

Upsun and Edgee partnership

Upsun is partnering with Edgee to address three persistent challenges in modern web analytics: data completeness, privacy compliance, and performance impact.

By integrating Edgee’s edge‑native analytics capabilities with Upsun’s platform, organizations can collect high‑quality data while respecting user privacy and maintaining fast experiences.

• Built‑in privacy by design: Supports compliance requirements without bolted‑on tooling.
• Performance‑first analytics: Sub‑10ms processing ensures analytics don’t degrade user experience.
• Simplified vendor landscape: One integrated solution instead of fragmented analytics stacks.

For organizations under increasing regulatory scrutiny, this partnership reduces both compliance risk and architectural complexity. For more information, check out the documentation.

Origin and Fastly alerts & metrics in Console

Visibility is essential for cost control and reliability. Upsun now surfaces Origin and Fastly metrics directly in the Console, with the ability to configure alerts based on defined thresholds.

• Cost predictability: Avoid surprise overages by monitoring usage in real time.
• Centralized observability: Eliminate the need to jump between platforms to understand performance and traffic patterns.
• Proactive operations: Alerts enable teams to respond before issues escalate.

Built for scale, governance, and confidence

Every feature released in Q4 2025 reflects Upsun’s focus on helping organizations run critical workloads with confidence without sacrificing developer velocity. You code, we do the rest.
