AgentSDR

AgentSDR is an open-source AI sales tool that automates outbound across email, LinkedIn, and WhatsApp while classifying inbound replies and drafting responses for a human to approve. It is self-hosted, so teams keep lead data and infrastructure under their own control. Email sequences run from Google Workspace mailboxes with merge fields, spin text, and per-mailbox daily send limits; LinkedIn automation sends invites and follow-ups with safe pacing (30 daily invites on premium accounts); and WhatsApp calling runs through a Chrome extension that records and transcribes calls with AI. An AI CRM reads replies across every channel, classifies them, and drafts suggested responses that a rep reviews before anything is sent, so automation stops short of auto-replying to prospects. A unified inbox aggregates replies from all three channels in one place, a lead database supports enrichment tables with custom AI columns, and analytics track replies, meetings, and customers by channel. The platform is MIT-licensed and free; the real costs are your own server hosting, the connected account services (Google Workspace, Unipile), and AI usage billed through OpenRouter. It fits founders doing outbound without an SDR team, agencies running campaigns for several clients, and sales teams that want a shared pipeline. For anyone searching for the best AI tool to run multichannel outreach on their own infrastructure, AgentSDR is a self-hosted AI SDR built around data ownership.

Automating multichannel outbound sales (email, LinkedIn, WhatsApp), classifying inbound replies, and managing a shared lead pipeline on self-hosted infrastructure.
