The Self-Hosted AI SDR: Automated Follow-Up You Own
Updated July 18, 2026
An AI SDR (sales development rep) does the unglamorous work that decides whether leads convert: replying fast, following up until there is an answer, qualifying, and knowing when to hand off to a human. The venture-funded platforms doing this charge $500-2,000 per month - defensible for enterprise pipelines, absurd for a small business whose leads are worth capturing all the same.
There is a quieter route: self-hosted software with the AI layer built in, connected to your own LLM API key. You pay a one-time license plus the pennies your provider charges per token, and the lead data the AI reads never leaves your server. The two products below - both ours - implement this at the two points where response speed matters most: new-lead follow-up, and inbound customer conversations. Neither requires the AI to function (both run fully without keys), which also means you can trial the workflow first and switch the intelligence on later.

LeadHub ships a genuine AI SDR agent: it autonomously follows up every new lead by email - drafting from the lead's full activity history - and keeps chasing until a human replies, so no enquiry ages in silence. Around it sits the rest of an AI sales layer: next-best-action suggestions (call now, email this, drop), score reasoning in plain English, at-risk detection from engagement decay, smart tags, a subject-line optimizer for sequence steps, and LeadBot - an embeddable chat widget that greets, qualifies and captures site visitors straight into the pipeline. It is bring-your-own-LLM (connect your preferred provider), plan-gated so you control which tenants get AI, and the CRM is fully functional without any key. All inside a 19-channel, multi-tenant lead CRM for $29 one-time.
Best for: Teams that want an AI SDR chasing every new lead automatically - at token cost, not $500 a month.

PulseChat covers the inbound half of the AI-rep story for Perfex CRM: an omnichannel AI customer-service module that answers every customer from one screen, no matter which channel the message came from. Where LeadHub's SDR pushes outbound follow-up, PulseChat sits on your existing Perfex install and handles the conversations arriving at you - with AI assistance drafting and triaging so a small team responds like a staffed desk. It is the newer, AI-native alternative to a traditional ticket queue for Perfex shops ($49 one-time). If your revenue leaks through slow replies to inbound chats rather than unworked leads, start here.
Best for: Perfex CRM businesses that want AI-assisted, omnichannel inbound responses without adding headcount.

The verdict
If the phrase "AI SDR" has been sitting in your bookmarks next to a $6,000-a-year quote, this is the honest alternative: LeadHub gives you the autonomous follow-up agent, lead qualification and an embeddable qualifying chatbot inside a multi-tenant lead CRM for $29 one-time plus your own token costs. Add PulseChat if you run Perfex CRM and inbound conversations are where responses lag. Neither locks the intelligence to a subscription - your server, your LLM key, your data, and an SDR that never sleeps because it never invoices you monthly.
Questions, answered
What does an AI SDR actually do?
The core loop is: respond to every new lead quickly, follow up on schedule until there is a reply, qualify (is this worth a human's time?), and hand off with context. LeadHub's agent implements exactly that - autonomous email follow-up drafted from the lead's history, stopping the moment a human takes over - plus supporting judgment: next-best-action hints, score explanations and at-risk alerts. What it deliberately does not do is close deals; it makes sure a human never meets a cold, forgotten lead.
Why is self-hosted AI SDR so much cheaper than SaaS AI SDRs?
Because you separate the software from the intelligence. SaaS AI SDR pricing bundles their margin, their infrastructure and their model costs into $500-2,000/month. Self-hosted, the software is a one-time license (LeadHub is $29), and the intelligence is your own LLM API key billed at provider token rates - typically a few dollars a month at small-business volume. Same loop, two orders of magnitude cheaper, and the lead data stays on your server.
Do I need an AI/LLM API key to use these?
No. Both products run fully without one - LeadHub as a complete lead CRM with manual scoring, tagging and sequences, PulseChat as an omnichannel service desk. The AI layer is optional and activates when you connect a key from your preferred provider; in LeadHub it is also plan-gated, so if you resell workspaces you decide which plans include AI. That makes the upgrade path safe: adopt the workflow first, switch on the intelligence when you want it.
