Verid
Verid
Verid is a developer-first web change detection API for monitoring any webpage for changes through structured data, not screenshots. Instead of alerting when a page visually changes, Verid extracts the exact field you care about, such as price, version, stock status, API response value, or availability, then fires a webhook only when a predicate you define is true. It is built for state monitoring, not screenshot diffing, giving developers structured extraction, durable state, field-level diffing, and predicate-driven delivery in one loop. Every monitor runs on a schedule you set through a full REST API with an OpenAPI 3.1 spec, so teams write the configuration while Verid runs the infrastructure. The pipeline follows five stages; fetch, extract, diff, predicate, and deliver. Verid starts with static fetch, automatically falls back to a headless browser when needed, and can escalate to a residential proxy when a site is harder to access.Starting Price: $19 per month -

Apptimized SafeBox
Apptimized
The software you use within the IT environment impacts the productivity of your team and business. But, what if software doesn't fit or you can't use it within the corporate infrastructure? It can cause the growth of Shadow IT and jeopardize your IT estate, from software contamination to the failure of the entire system. Apptimized SafeBox allows you to use a managed sandbox environment in the cloud and work with non-standard workloads depending on your needs. Use cloud-native safeboxes to assess, test, evaluate, package, etc. before installing software on your devices. Any data produced using SafeBox and your installed apps are kept kept as long as you need. Also, SafeBox provides you with a snapshot feature that allows you to switch between SafeBox states, setups, and configurations. If you wish to go back to the initial or intermediate state - simply revert it to a snapshot. -

Cyberstanc Swatbox
Cyberstanc
Traditional malware sandboxing and simulation solutions may fall short of detecting emerging threats because they often rely on static analysis and pre-defined rules to detect malware. SWATBOX is an advanced malware simulation and sandboxing platform that utilizes simulated intelligence technology to detect and respond to emerging threats in real-time. It is designed to emulate a wide range of realistic attack scenarios, allowing organizations to assess the effectiveness of their existing security solutions and identify any potential vulnerabilities. SWATBOX utilizes a combination of dynamic analysis, behavioral analysis, and machine learning to detect and analyze malware samples in a controlled environment. It uses real-life malware from the wild, which involves creating a sandboxed environment that simulates a real-world target and seeding it with decoy data, to lure attackers into a controlled environment where they can be monitored and their behavior studied. -

FortiSandbox
Fortinet
Unlike previous generation of viruses that were non-sophisticated and low in volume, antivirus tools were sufficient to provide reasonable protection with their database of signatures. However, today’s modern malware entails new techniques such as use of exploits. Exploiting a vulnerability in a legitimate application can cause anomalous behavior and it’s this behavior that attackers take advantage of to compromise computer systems. The process of an attack by exploiting an unknown software vulnerability is what is known as a zero-day attack aka 0-day attack, and before sandboxing there was no effective means to stop it. A malware sandbox, within the computer security context, is a system that confines the actions of an application, such as opening a Word document, to an isolated environment. Within this safe environment the sandbox analyzes the dynamic behavior of an object and its various application interactions in a pseudo-user environment and uncovers any malicious intent. -

VibeSDK
Cloudflare
Cloudflare has released VibeSDK, a full-stack, open source vibe coding platform that you can deploy with one click to host your own AI-powered application builder. The platform integrates LLMs (via an AI Gateway) to generate, debug, and iterate code in real time; provides isolated, secure sandboxes (or container-based environments) per user session for executing untrusted code; offers live previews and streaming logs to help users test and troubleshoot as they build; and uses workers for platforms to deploy each generated app at scale, with isolation between tenants. VibeSDK includes project templates, support for export to GitHub or a user’s Cloudflare account, cost and performance observability, caching for repeated requests, and multi-model support through routing across AI providers. It is designed to let teams offer internal or customer-facing “no-code/low-code” platforms, letting non-programmers spin up landing pages, prototypes, or applications from natural language prompts.Starting Price: Free
