Independent Chrome Extension Studio
Lukas Labs is an independent studio building small, privacy-first Chrome extensions. No bloat, no tracking, no account required for the free versions — each tool is built to solve one problem properly.
Product list — TabCellar is on the Chrome Web Store; more tools will be added as they launch.
Products
Every Lukas Labs product is sold from this website, under one store. Each product has its own page with its own features, pricing and data handling.
Chrome tab & session manager. Automatic snapshots, backup history and crash recovery — and your tab data stays in your own browser. Free $0, Pro $7/month or $56/year.
Website blocker & focus timer. Block distracting websites, paths, and keywords — no account needed. The free version covers up to 2,000 sites. Pro $6.99/month, $19.99/year, or $49.99 one-time.
How we build
Each tool solves one problem properly instead of bundling ten half-finished features.
Your data stays on your own device wherever the product allows it. What a product stores is stated on its own page.
Free means free, Pro prices are shown on the pricing page, and every Pro purchase is covered by a 14-day, no-questions-asked refund.
