About Sidereal Cog

Engineered for the everyday

Sidereal Cog builds browser extensions that solve mundane problems. The kind of small frustrations you deal with every day but never quite get around to fixing.

We're not trying to revolutionize your workflow or change how you use the internet. We're just making the annoying stuff less annoying.

Our Approach

Start simple. Every extension does one thing well rather than trying to do everything adequately.

Stay practical. If it doesn't solve a real problem you've personally experienced, it doesn't get built.

Keep it clean. No bloat, no unnecessary features, no data collection. Just the tool, doing its job.

What We Build

Browser extensions for Chrome (and other Chromium browsers). Each one tackles a specific everyday problem:

  • Managing the small stuff that clutters your workflow
  • Organizing information you reference regularly
  • Streamlining repetitive tasks you do without thinking

If you've ever thought "there should be a simple tool for this," we probably agree.

Who's Behind This

Sidereal Cog is a solo developer project. One person building tools that solve problems they've run into, then sharing them in case they're useful to others.

No team, no venture funding, no growth metrics. Just practical extensions, engineered for everyday use.
