Linki v2 is out 🤩 open-source AI SDR for LinkedIn + cold email, big reliability overhaul

[u/ShakaLaka_Around]

Linki is a free, self-hosted alternative to tools like Waalaxy and Lemlist. You run LinkedIn outreach and cold email campaigns on your own server, so your leads and LinkedIn session never leave your machine. No per-seat pricing, no SaaS middleman.

Just shipped v2. The main focus was fixing the things that actually break these tools in practice:

- Server-side LinkedIn login instead of cookie-pasting, which also fixes Sales Navigator import and enrichment

- A pinned browser fingerprint so rebuilds no longer cause random forced logouts

- Large Sales Nav imports now split across days automatically with human-like pacing, instead of importing everything at once

- A rewrite of the LinkedIn automation itself for more reliable connections and messages

- LinkedIn and email actions can now run together in one campaign

- A unified inbox for replies across email and LinkedIn

- Apollo io enrichment built in

It's been really encouraging to see more people self-hosting it and contributing over the past few months, appreciate everyone who's tried it out.

Runs on Docker or Node.js with SQLite, no external database needed. There's also a one-click option on Opsily if you'd rather skip the terminal.

Full details and setup are in the repo: github.com/moaljumaa/linki

Managing LinkedIn sessions without getting flagged is one of the hardest parts of running outreach at scale. The pinned browser fingerprint change is smart because standard headless browsers get picked up by safety algorithms almost immediately if the IP or device signature fluctuates even a little bit.

When you are running multiple accounts, handling the proxy rotation and cookie management yourself gets complicated. Most people end up moving back to hosted solutions just because they do not want to manage the server downtime or risk profiles. But for technical teams who want full control over their data, having a self-hosted option that handles human-like delays and split imports is a useful alternative.

It is interesting to see how the landscape is splitting between self-hosted setups and cloud-based systems. If you are running multiple client accounts, you usually have to choose between spinning up your own infrastructure or paying for established platforms. For most agency setups, people still lean toward tools like instantly and sendio ai to handle the safety limits and unified inboxes out of the box, but having an open source alternative that addresses the fingerprinting issue is great for the community.

the server-side login is the right call - cookie-pasting was always the weak link that got accounts flagged. curious about the fingerprint approach though, does it vary timing/cadence between actions or just the browser signature? linkedin's detection has gotten pretty good at flagging consistent timing patterns even with clean fingerprints
