Speed-Check is a free, open, and privacy-first internet speed test that measures your download speed, upload speed, ping, and jitter directly in your browser — no signup, no app install, and no tracking of personal data.

Unlike most mainstream speed tests, Speed-Check runs on the M-Lab NDT7 protocol (the same open measurement standard used by Google Search and independent researchers) combined with Cloudflare edge endpoints for global coverage. Results are typically within 2–5% of Ookla Speedtest, but without the heavy ads, account walls, or invasive analytics.

Key Features

• ⚡ Full metrics by default — download, upload, ping, and jitter (no hidden upload like Fast.com)
• 🔒 Privacy-first — no cookies, no personal data stored, GDPR-compliant
• 🌍 Global server network — M-Lab + Cloudflare endpoints worldwide
• 🧩 Free embeddable widget — add a speed test to any website in 3 sizes (no paid tier)

CodeHerald provides a new way to keep track of your code review queue, grouped by your next action needed.

When would you use CodeHerald?

• You work in a team that does code reviews.
• Your team receives ad-hoc code review requests via multiple channels: DMs, emails, bookmarks of filtered lists.
• Your team sometimes loses track of small pull requests, delaying them days.
• Your team find ad-hoc code review requests distracting, but cannot put a finger on why.
• Your team tried different strategies to improve code review process, and none of them felt right.

If any of the above is true, CodeHerald will help you.

What can CodeHerald do for you?

CodeHerald groups pull requests by next action: must review, needs an update, can be merged. It allows you to replace slack, emails, filters, and browser bookmarks with one single page that you can open at a glance and decide which PR to tackle next.
