Linki v2: Open-Source AI SDR for LinkedIn + Cold Email with Self-Hosted Agent

Linki v2 is an open-source, self-hosted AI SDR (Sales Development Representative) that automates LinkedIn sequences and cold email campaigns. Unlike SaaS tools like Waalaxy or Lemlist, there's no per-seat pricing and your data stays on your machine. You connect any LLM via OpenRouter — Claude, GPT-4o, Mistral, etc. — and the AI agent writes every message individually for each lead.

Core Architecture

The AI agent is now the centerpiece. It uses a 3-layer prompt system:

• Global context: describes your business and offer
• Campaign-level instructions: per-campaign goals and constraints
• Per-step prompts: custom instructions for each action (connect, message, follow-up)

This means the agent writes with full context instead of filling a static template.

Key Features in v2

• Unified campaigns: LinkedIn and email steps in one sequence. Example: visit → connect → wait 2 days → LinkedIn message → wait 3 days → cold email.
• Unified inbox: all email replies from all campaigns in one place, plus LinkedIn reply detection.
• Apollo enrichment: connect your Apollo key, click enrich on any list to get verified emails and company data.
• Improved reliability: rewritten DOM targeting and message delivery gives ~63% improvement in connection reliability. Randomized pacing on imports reduces bot detection risk.
• AI cost tracking: every generation logs model, token count, and cost.

Hosting

Deploy via Docker Compose or manual Node.js. No external database needed — uses SQLite. A one-click deploy option is available on Opsily.

This is a solid self-hosted alternative for dev teams that want AI-driven outreach without data leaving their infrastructure.
