About Tell Me When Down
Tell Me When Down is an uptime monitoring and security scanning tool specifically designed for solo founders and developers building with AI agents. Rather than just checking if a URL responds, it monitors your application across three distinct operational depths to ensure both availability and safety.
The platform inspects your project through three layers:
- Public URL Scan: A free security scan evaluating your public domain for SSL issues, response headers, DNS configuration, and domain spoofing risks.
- GitHub Code Scan: A read-only GitHub App that analyzes your codebase to detect known vulnerabilities (CVEs) and leaked secrets.
- SDK Integration: Deep monitoring for critical backend components, including databases, Stripe webhooks, and background cron jobs.
With 60-second uptime checks and plain-English alerts, Tell Me When Down simplifies maintenance. Instead of requiring deep security expertise, every issue detected comes with a pre-formatted fix. Users can simply click "Copy for your AI tool" to feed the precise resolution directly into the AI coding agent used to build the application.
Pros of Tell Me When Down
- Monitors applications across three layers: public URL, code repository, and backend SDK
- Provides 60-second interval uptime checks with clear, plain-English alerts
- Includes a 'Copy for your AI tool' feature to effortlessly pass fixes to AI coding agents
- Offers a free public URL security scan for SSL, headers, DNS, and spoofing risks
Cons of Tell Me When Down
- Requires installing a GitHub App and integrating an SDK for deep code and backend monitoring
- Designed primarily for solo founders and simple workflows rather than large enterprise teams
Frequently Asked Questions
What is Tell Me When Down?
Tell Me When Down is an uptime monitoring and website security scanning tool built for solo founders. It monitors public URLs, code repositories, and backend services, providing plain-English alerts and ready-to-paste fixes.
What are the three depths of monitoring?
The tool scans public URLs (SSL, headers, DNS, and spoofing), connects via a read-only GitHub App to detect CVEs and leaked secrets in code, and uses an SDK to monitor databases, Stripe webhooks, and cron jobs.
How often are uptime checks performed?
Tell Me When Down performs uptime checks every 60 seconds.
How does the 'Copy for your AI tool' feature work?
Every security finding or issue comes with a prepared fix. Clicking 'Copy for your AI tool' copies formatted instructions that you can paste directly into the AI agent that helped build your app.
About framejs
framejs is an open-source tool designed to build and share interactive web applications that exist entirely within a URL. Unlike traditional platforms such as Streamlit or Observable that require active backend servers to host code and maintain state, framejs encodes your app's entire architecture—including JavaScript, CSS, and application state—directly into the URL itself.
With framejs, there is no need for server hosting infrastructure, deployment pipelines, or complex build setups. Users can prompt AI to construct an application or data visualization, copy the generated link, and distribute it anywhere. The application runs natively in the browser, providing a light, serverless way to create and present interactive web tools instantly.
Pros of framejs
- Encodes JavaScript, CSS, and application state directly into the URL
- Requires zero server hosting, deployment pipelines, or build setups
- Open-source software that can be used standalone or embedded into existing apps
- Works seamlessly with AI prompting for fast app creation and sharing
Cons of framejs
- Does not support server-side backend logic or persistent backend databases
- Execution is strictly limited to client-side browser capabilities
Frequently Asked Questions
How does framejs work?
framejs encodes the full application codebase—including JavaScript, CSS, and state—directly into the URL string. When opened, the application executes entirely within the user's web browser without connecting to a dedicated backend server.
How does framejs differ from Observable or Streamlit?
Observable and Streamlit rely on backend servers that must remain online to run interactive code. framejs completely removes the server requirement by storing the code and state inside the URL payload.
Is framejs open source?
Yes, framejs is open source. You can use it as a standalone tool or incorporate it directly into your own software projects.
Do I need to host or deploy my framejs apps?
No. framejs requires no deployment, hosting, or build process. You simply share the generated URL, and the interactive app runs wherever the link is opened.
