Stop paying $100 per seat. Linki combines LinkedIn automation and cold email sequences into one self-hosted AI SDR. Maintain total data privacy while scaling your outbound without the per-user tax.
Trusted by fast-moving teams
Why switch to an open source email outreach tool?
Most cold email platforms charge you for every team member and every inbox. If you are an agency with five reps, you are likely burning $500 a month just for the right to send mail. This is the 'SaaS Tax.' It eats your margins before you even book a meeting.
Linki changes the math. It is an open source AI SDR that lives on your own server. You don't pay for seats. You don't pay for inboxes. You pay for the infrastructure. By self-hosting Linki on Opsily, you keep your costs flat while your outreach volume grows.
Beyond cost, there is the privacy factor. SaaS tools store your leads and LinkedIn cookies on their servers. Linki keeps all that PII (Personally Identifiable Information) in your own SQLite database. Built for the Node.js 22 stack, it is fast, secure, and entirely under your control.

Why host your open source email outreach tool on Opsily?
We handle the server. You handle the leads. The perfect middle ground between complex self-hosting and expensive SaaS.
GDPR by design
Your Linki instance is hosted in Germany. Lead data and LinkedIn cookies never leave the EU. This is a massive compliance win for European agencies.
Infinite Scalability
Add 10 inboxes or 100. Because you own the server, Opsily does not care how many accounts you connect. One flat monthly bill for the hardware.
Zero-Config Deployment
Don't touch a terminal. We deploy the Node.js 22 environment, the SQLite database, and the Linki core in under three minutes.
Built for teams who need reliability
EUR 800 a year for tools that used to cost us multiples of that. We replaced HubSpot, Make.com, and our password manager with self-hosted apps on Opsily. One provider, one fee.

We were paying per user on everything and it added up fast. Now we run five apps for less than one of those old plans. My finance team finally stopped asking questions.

Wanted to use n8n for ages but the self-host part always stopped me. Opsily just handled it. Got the power without becoming an IT person overnight.
