BL.INK is a polished link-management platform that does branded domains and analytics well, aimed at businesses. KooLink is what we built. The comparison is about where each is strongest.
Price
BL.INK. A subscription product. Free tier is a limited trial; real branded-domain and analytics use sits behind a monthly plan.
KooLink. Free forever. Unlimited links. No signup to shorten. No monthly bill.
Signup
BL.INK. An account is required to create and manage links.
KooLink. No account to shorten. Paste a URL, get a link. You only create an account for payout-linked analytics.
Custom domains
BL.INK. A strength. You put links on your own brand domain, which is the main reason teams choose it.
KooLink. Custom branded domains are not the current focus. The product is built for fast, free, unlimited shortening plus the AI-agent integration.
Analytics
BL.INK. Deep analytics on a paid plan — business-grade dashboards.
KooLink. Honest per-link views on a free plan, with bot traffic filtered out.
The 2026 difference: MCP
The thing that separates them: BL.INK does not expose a hosted MCP server. KooLink does.
https://mcp.kool.ink
Point your MCP client (Claude, Cursor, Windsurf, VS Code with Continue) at it and the agent gets a shorten_url tool. Ask the agent to shorten any URL and it does — no browser, no copy-paste.
There is a terminal one-liner too:

Bottom line
- You want business-grade branded links and deep analytics, happy to pay → BL.INK is a strong choice.
- You want free, unlimited, no signup, and a shortener your AI agent can call → KooLink.
If branded-domain management and paid analytics are the whole point, BL.INK wins. If free, unlimited, and agent-ready matter, KooLink is the fit.
