Paste your custom scheme URL
Enter any URL that uses a custom protocol like slack://, obsidian://, zoommtg://, or notion://. Web pages, email and most documentation tools only make web links clickable, so these end up as plain text.
Choose your redirect mode
Auto-redirect opens the link immediately when someone clicks it. Manual mode shows a confirmation page first. Links to websites (http and https) always get the confirmation page. Compression uses LZ encoding to shorten the URL without a database.
Share the link
Copy the generated https link and paste it where the original wouldn’t work: Notion pages, Slack messages, emails, GitHub READMEs, wikis. Clicking it opens the original link in the app.
What is a custom scheme URL?+
A custom scheme URL starts with something other than https://, like slack://, obsidian:// or zoommtg://. Apps register these schemes so a link can open a specific channel, note or meeting. Most websites, email clients and wikis only make web links clickable, so these show up as plain text.
Why do slack:// and obsidian:// links break in Notion?+
Notion, like most web apps, only keeps links that start with http, https, mailto or tel. A pasted slack:// or obsidian:// link loses its link and stays as plain text. LinkOpen wraps it in an https address that Notion accepts, and opening that address hands the original link to the app.
Does LinkOpen store my URLs?+
No. Your URL is compressed into the link itself, and there is no database behind it. One caveat: the site uses Google Analytics and Vercel Analytics, which record the address of each page visited, and for a shared link that address contains the encoded URL.
Is LinkOpen free?+
Yes, LinkOpen is free and open source. There are no usage limits, no signup requirements, and no premium tiers. The source code is available on GitHub.
How does the compression work?+
LinkOpen uses LZ-string compression with a custom dictionary of common URL patterns. The URL is first pattern-matched against known schemes, then compressed using LZ encoding, and finally made URL-safe. Nothing is looked up when the link is opened: the link itself carries the whole URL.
