Why Extensions Market
Built by someone who needed
these tools himself
Founded by Vladislav Gerasimchuk · San Francisco, CA · [email protected]
One job, done exceptionally
Each extension is laser-focused on a single task. No bloat, no upsells inside the tool, no feature creep. Just the thing you installed it for.
Privacy first
Your data stays yours. We don't sell it, don't mine it, and don't share it. Extensions only request the permissions they actually need.
Actively maintained
When a site changes its layout, we ship a fix. When Chrome updates its APIs, we're already updated. These tools are used by us daily.
Free to start
Every extension has a meaningful free tier. Try it, see the value, then decide. No credit card required to get started with any of them.
Chrome Manifest V3
All extensions are built on the latest Chrome MV3 standard — faster, safer, and fully compliant with Chrome Web Store policies.

Each product does exactly one job and does it well — no bloat, no upsells inside the tool, no feature creep. All Chrome extensions are built on Manifest V3 and only request the permissions they actually need. Because the tools are used daily by the developer, they stay updated when sites change their layouts or Chrome releases API changes.
Do you offer customer support?
Yes. Support is handled directly by the developer who built the product. Email [email protected] and you'll get a response from a real person — not a support bot.
Which browsers do the Chrome extensions support?
All Chrome extensions work on Google Chrome and Chromium-based browsers including Microsoft Edge and Brave. They're built on Manifest V3, the latest Chrome extension standard, and fully comply with Chrome Web Store policies.
