Sandbox Environments for AI Agents: A Full, Isolated Stack for Every Task

A code sandbox like Daytona or E2B isolates a process. A sandbox environment isolates a whole stack: services, databases, queues and configuration, cloned for one agent task and destroyed when it is done. Here is how sandbox environments work, what they are good for, and how to run them on Qovery. Romaric founded Qovery to make Kubernetes accessible to every engineering team. He writes about platform strategy, developer experience, and the future of cloud infrastructure.

Security Just Hit Machine Speed

What if we could eliminate vulnerabilities before they become a problem? Neil Watkins from Burns & McDonnell explains how AI, automated security assessments, and Harness CI/CD capabilities could transform vulnerability management. From reducing attack surfaces to rapidly responding to critical zero-day vulnerabilities, the future of security is about moving faster without slowing down developers.

The Upsun Performance Agent: a diagnosis instead of a call graph

The data to explain a slow endpoint is usually already sitting in your project. Blackfire has the profile. Continuous profiling has the flame graph. The traffic numbers show which route matters. The code is in git. What takes the afternoon is putting those four things next to each other and working out which function is responsible. That afternoon is what the Upsun Performance Agent is for.

Capping the AI free-for-all? Know what each dollar returns first.

Most companies gave everyone AI access and thought they’d sort out the costs later. Engineering, support, product, marketing, and finance all got licenses to the best models. The early results looked good, and for a while it didn’t matter there wasn’t an explicit business case. Let’s call the first half of 2026 the free-for-all period for many companies. AI adoption spread across the org fast, people and teams loved it, and then the invoices started coming in.

Optimize AI costs with Agent Observability

AI agent costs accumulate along more dimensions than a model-call count. Spend is a product of both which models you call and how the agent is architected: how many turns the loop runs, how many tools it invokes, how much retrieved context it carries, and how much of that context is re-sent on every turn. Provider bills tell you how much you spent, but they’re keyed to API keys and models instead of the applications and workflow steps that generated the calls.

7 Best Cold Email Agencies for B2B Startups

Cold email remains one of the fastest ways for a young B2B company to reach buyers who have never heard of it. Doing it well takes clean data, sharp copy and sending domains that stay out of spam. Most startups do not have the people to run all of that in house. The seven agencies below sell cold email as a managed service, and every detail comes from their own websites. Prices appear only where an agency publishes them.

Hook vs. Transitional Hook vs. Text Hook: What's the Difference? 2026

A hook is any opening that grabs attention in the first 1-3 seconds of a video. A text hook is a hook made of words on screen. A transitional hook is a hook made of motion, such as a quick cut, zoom or wipe that jumps between scenes. Text and transitional hooks are both types of hooks, and many strong videos use them together.

The Office Network Passed Its Speed Test. Then Everyone Came to Work

The IT crew wrapped up the office network install on a Friday afternoon. Internet was live. Switches hummed in the cabinet. A laptop parked beside an access point pulled a clean 940 Mbps down and a respectable upload to match. Everyone went home satisfied. Monday morning told a different story. By 9:20, the complaints rolled in. Video calls froze mid-sentence. Wi-Fi dropped in the east corridor. Finance couldn't reach the shared drive. Nothing in the Friday test predicted any of it.
