The OpenAbby Platform

An open-source AI agent gateway built in Go. Deploy agents across Slack, Teams, WhatsApp, Telegram, email, phone, and custom integrations. Written from the ground up for enterprise security and performance.

Core Platform

Multi-Channel Agent Gateway

One platform routes AI agents across every communication channel your organization uses. Agents respond in Slack, answer the phone, process emails, and manage tickets — simultaneously.

  • Slack, Microsoft Teams, WhatsApp, Telegram
  • Email (IMAP/SMTP with attachment processing)
  • Phone/SIP with real-time voice AI
  • Custom webhooks and REST APIs
  • SMS and MMS via carrier integration

Intelligence

Smart Model Routing

OpenAbby automatically routes requests to the right AI model based on complexity, cost, and latency requirements. Simple questions hit fast, cheap models. Complex reasoning escalates to powerful ones.

  • Automatic tier selection (fast → standard → reasoning)
  • Per-agent and per-user budget controls
  • Fallback chains when models are unavailable
  • Local model support (run on your own GPUs)
  • Zero vendor lock-in — swap providers in config
routing:
  tiers:
    fast: gemini-3.1-flash
    standard: gemini-2.5-pro
    reasoning: claude-opus
  strategy: cost-optimized
  fallbacks:
    - reasoning → standard → fast
  budgets:
    per_agent: $50/month
    per_user: $20/month
Tools

3,000+ Integrations

Agents connect to the tools your business already uses. CRM, analytics, project management, code repositories, databases, cloud infrastructure — all through secure, auditable integrations.

  • Salesforce, HubSpot, Pipedrive CRM
  • Jira, Linear, Asana, Monday.com
  • GitHub, GitLab, Azure DevOps
  • Stripe, QuickBooks, Xero
  • AWS, Azure, GCP infrastructure
  • PostgreSQL, MongoDB, Redis databases
  • Custom API connectors in minutes

Voice

Real-Time Voice AI

Agents answer the phone. Real conversations with natural speech, not IVR menus. Streaming speech-to-text, intelligent turn detection, and neural text-to-speech with customizable voices.

  • Sub-second latency end-to-end
  • Natural interruption handling
  • Multiple voice personas per agent
  • SIP trunk integration with any carrier
  • Call recording and transcript logging
  • Warm transfer to human agents

Memory

Persistent Knowledge & Learning

Agents remember context across conversations, learn from interactions, and build organizational knowledge over time. Vector databases, knowledge graphs, and structured memory systems.

  • Vector database for semantic search
  • Knowledge graph for relationship mapping
  • Per-user and per-project memory
  • Automatic knowledge consolidation
  • Memory access controls and audit trails

Architecture

Built in Go for performance

OpenAbby is a complete rewrite in Go — compiled, fast, and lightweight. Runs on a Raspberry Pi or a rack of servers.

~10MB Binary

Single compiled binary. No runtime dependencies, no Node.js, no Python. Deploy anywhere.

Sub-ms Routing

Go's concurrency model handles thousands of concurrent agent sessions without breaking a sweat.

Self-Hosted

Your infrastructure, your data. No cloud dependency. Runs on bare metal, VMs, Docker, or Kubernetes.

Open Source

Every line of code is yours. MIT licensed. Fork it, modify it, audit it. No black boxes.
