About fast-cli and RealUptime.io

In their own words, as submitted to SaaSHub.

RealUptime.io

No description of fast-cli yet.

Most status pages collapse the whole world into one green dot. If you're up in Virginia but down in Frankfurt, that dot is lying to your customers. RealUptime checks from four regions (US East, US West, Europe, Asia Pacific) and shows every region's reading by default, so a partial outage...

Questions & Answers

As answered by people managing fast-cli and RealUptime.io.

What makes your product unique?

RealUptime.io's answer:

Every check runs from four regions and every region's reading is shown by default, on the public status page, not buried in a dashboard. Most tools collapse the world into one green dot, which means a regional outage can hide behind a healthy average. RealUptime treats "up in Virginia, down in Frankfurt" as information your customers deserve to see. That, and flat pricing: no per-subscriber fees, no per-check metering.

Why should a person choose your product over its competitors?

RealUptime.io's answer:

Two reasons. First, honesty by default: per-region status readings your customers can trust, instead of a single dot that averages problems away. Second, predictable cost: incumbents charge per status-page subscriber or per check, which punishes you for growing. RealUptime is a flat monthly price, the free tier is permanent, and one platform covers status pages, uptime monitoring, and error tracking so you are not stitching three vendors together.

How would you describe the primary audience of your product?

RealUptime.io's answer:

Developers, small software companies, indie founders, and agencies who need to tell their own customers the truth about an outage. Teams big enough to need a status page and monitoring, but not big enough to want enterprise observability pricing.

What's the story behind your product?

RealUptime.io's answer:

I spent 8 years managing a T-Mobile retail store before building this. Retail teaches you that customers forgive problems but never forgive being lied to. When I looked at status page tools, the standard design was a single green dot that stays green while a whole region is down. I built RealUptime as the tool I would trust as a customer: every region shown, flat pricing, and a free outage tracker measured by our own probes instead of trusting vendors' own status pages.

Which are the primary technologies used for building your product?

RealUptime.io's answer:

Next.js and TypeScript, PostgreSQL, and a probe fleet deployed across four regions on Fly.io.

  • macOS Command-Line Tools You Might Not Know About
    There is also a CLI client for speedtest.net[1] and fast.com[2]! Not included with MacOS, of course, but nice to have around. [1] https://www.speedtest.net/apps/cli [2] - Source: Hacker News / over 3 years ago
  • Poor forwarding performance between two WireGuard tunnels
    Ran command-line tests on the server for Fast.com using awesome fast-cli and SpeedTest.net CLI utility. Both showed 1 Gbps performance via wg1 tunnel from server to internet. Source: about 4 years ago
  • App To Monitor For Slow Speed, Not Total Outage
    You could use something like fast-cli to get your speed, log it and the date/time to a file if it's too low, and sleep 5 minutes or whatever. Source: about 5 years ago
