IsDown was built out of frustration at 4 AM. Nuno Tomas, founder and on-call engineer, spent 30 minutes debugging an alert before realising the cloud provider had an outage posted on their status page, but nobody was watching it. That night, he decided there had to be a better way.

Today, IsDown monitors 6,000+ cloud and SaaS services, has performed over 1 billion status checks, has detected 520,000+ outages, and has sent 5.2 million+ notifications. Trusted by IT, DevOps, and engineering teams since 2020.

What makes IsDown different: it reads official vendor status pages directly, not just crowdsourced reports. Combined with early detection signals, it catches outages before vendors acknowledge them, sometimes hours ahead. In January 2026 alone, IsDown detected 101 incidents that vendors never officially reported.

Key capabilities: - Monitor 6,000+ services from one dashboard. Filter by service, component, or severity. - Get alerts within seconds in Slack, PagerDuty, Datadog, Microsoft Teams,ย Incident.io, FireHydrant, Grafana, Discord, SMS, and wherever your team works. - Track scheduled maintenance across all vendors in a live feed and calendar, so nothing slips through unnoticed. - Create public or private hosted status pages with your own domain and branding. - Monitor your own APIs, endpoints, and SSL certificates from US, EU, and Asia. - Built for enterprise: SSO (SAML, OAuth), SOC 2 Type II in progress, MCP Server for AI assistant queries.

Setup takes 5 minutes. No engineering required. 14-day free trial, no credit card needed.

Babel features and specs

  • JavaScript Version Compatibility
    Babel allows developers to write code using the latest JavaScript features and syntax, and transpile it into a version of JavaScript that can run on older browsers. This ensures greater compatibility across different environments.
  • Future-Proof Code
    With Babel, developers can start using upcoming JavaScript features today. This means that codebases can stay modern and developers can take advantage of new functionalities without waiting for full browser support.
  • Ecosystem and Plugins
    Babel has a rich ecosystem of plugins and presets that can extend its capabilities, making it highly adaptable to different project needs. This modularity allows for customization and enhancement of the build process.
  • Integration with Modern Development Tools
    Babel integrates well with various development tools such as Webpack, making it easier to include in existing build processes and workflows. This helps streamline development and maintain efficient workflows.
  • Community and Support
    Babel has a large and active community, which means extensive documentation, tutorials, and support forums. This can be particularly useful for troubleshooting and staying updated with best practices.

Possible disadvantages of Babel

  • Performance Overhead
    Transpiling code with Babel introduces a performance overhead during the build process. This can slow down development workflows, especially for large codebases with many files.
  • Configuration Complexity
    Setting up Babel can be complex, particularly for beginners. The numerous options and plugins available can sometimes be overwhelming and require significant time to configure correctly.
  • Source Map Issues
    Generating accurate source maps can sometimes be tricky with Babel, leading to difficulties in debugging. Misconfigured source maps can make it harder to track down issues within the original source code.
  • Dependency Bloat
    Including Babel in a project can add a significant number of dependencies. This dependency bloat can increase the size of the project and potentially introduce maintenance challenges or security vulnerabilities.
  • Learning Curve
    There is a learning curve associated with Babel, especially for developers who are new to modern JavaScript tooling. Understanding how Babel works and how to effectively use its features can take time and effort.

Analysis of Babel

Overall verdict

  • Yes, Babel is widely considered a good tool for modern JavaScript development. It eases the use of cutting-edge JavaScript features and ensures broader compatibility, which is crucial for many projects. Its active community and continuous updates reflect its standing as a reliable and well-supported choice.

Why this product is good

  • Babel is a popular JavaScript compiler that allows developers to use the latest JavaScript features while maintaining compatibility with older environments that may not support these features natively. It transforms modern JavaScript code into a version that can run in current and older browsers or environments. Babel is highly configurable and has a rich ecosystem of plugins and presets that enable developers to tailor it to their specific needs, making development smoother and more efficient.

Recommended for

    Babel is recommended for web developers who want to write modern JavaScript but need to ensure that their code remains functional across different environments and older browsers. It is also valuable for projects where developers aspire to use the latest ECMAScript features without waiting for broad native support.

Questions & Answers

As answered by people managing IsDown.app and Babel.

What makes your product unique?

IsDown.app's answer

IsDown monitors official vendor status pages directly, not just crowdsourced reports. This means alerts include real incident context: what broke, which components are affected, and real-time resolution status. Not just "something is down." Combined with crowdsourced early detection signals, IsDown can catch outages before vendors acknowledge them. In January 2026 alone, IsDown detected 101 incidents that vendors never officially reported. Every team monitoring cloud services already has uptime tools that ping their own URLs. IsDown tells you what is happening with the third-party services your stack depends on, before your users feel it.

Why should a person choose your product over its competitors?

IsDown.app's answer

Three reasons:

  1. Coverage: 6,000+ services monitored. If your vendor has a status page, IsDown monitors it.
  2. Speed and context: Alerts go out within seconds of an incident, with full context including affected components, official vendor description, and real-time updates. Not just a notification that something is wrong.
  3. IsDown does not replace your existing tools, it completes them. UptimeRobot and Pingdom tell you your own services are down. IsDown tells you which of your third-party vendors caused it, and exactly what is happening on their end. Setup takes 5 minutes. No engineering required.

How would you describe the primary audience of your product?

IsDown.app's answer

IsDown is built for IT managers, DevOps engineers, and SREs at companies that rely on multiple cloud and SaaS services, which means any team running on cloud infrastructure. The core audiences are DevOps and SRE teams who are on-call and need to know instantly when a third-party service causes an incident; IT managers responsible for vendor oversight and SLA compliance; MSPs and agencies managing cloud infrastructure for multiple clients; and engineering teams who want to stop wasting time debugging problems that turn out to be vendor outages. Customers span SaaS companies, schools, DevOps agencies, and enterprise IT teams across industries.

What's the story behind your product?

IsDown.app's answer

IsDown was built out of frustration at 4 AM. Nuno Tomas, the founder, was on-call when a PagerDuty alert woke him up. After 30 minutes of debugging, he realised the problem was not his code. It was the cloud provider. They had posted an outage on their status page, but nobody on the team was watching it. That night, he decided there had to be a better way. He built the first version of IsDown so his team would never be the last to know about a vendor outage. Founded in 2020, IsDown has since grown to monitor 6,000+ services, perform over 1 billion status checks, detect 520,000+ outages, and send 5.2 million+ notifications. The same problem Nuno solved for his team that night is now solved for IT, DevOps, and engineering teams around the world.

Who are some of the biggest customers of your product?

IsDown.app's answer

IsDown is used by IT, DevOps, and engineering teams across SaaS companies, MSPs, DevOps agencies, schools, and enterprise IT departments.

Which are the primary technologies used for building your product?

IsDown.app's answer

IsDown is a web-based SaaS application. The core product runs on modern cloud infrastructure with multi-region monitoring across US, EU, and Asia to ensure reliable status checks and fast alert delivery worldwide. IsDown integrates directly with Slack, PagerDuty, Datadog, Microsoft Teams,ย Incident.io, FireHydrant, Grafana, Rootly, Zendesk, and more, connecting alerts to wherever your team already works. For teams using AI assistants, IsDown offers an MCP (Model Context Protocol) Server that allows querying IsDown data directly from AI tools like Claude or ChatGPT.
