THE RUNTIME FOR
COORDINATED ENGINEERS.
Chat is a weak runtime. Tandem is an Engine-Owned Runtime for coordinated autonomous work. Built for serious engineering with blackboard orchestration, structured task state, and deterministic execution.
Tandem Engine
Headless orchestration core handling MCP catalogs and robust Declarative DAG states.
Tandem Client (TS)
TypeScript SDK for triggering workflow events and inspecting V2 Automations.
Tandem TUI
Console interface. Now featuring advanced coding-first shortcuts (`Alt+P`, `Alt+D`).
Tandem Client (Python)
Python mapping for data science teams interfacing with the Tandem Coder routines.
The AI Workspace That Actually Belongs to You
Stop renting your intelligence. Tandem is the local-first, zero-trust AI workspace designed for deep work, not just chat.
Native Intelligence
We don't just pass messages to an API. Tandem features a built-in vector database and long-term memory engine that runs locally. It learns from you without leaking your data.
True Ownership
Your data lives in a secure, encrypted vault on your drive. No cloud sync required. No "telemetry" spying on your ideas.
Infinite Extensibility
Turn Tandem into a Bio-informatics researcher, a Legal analyst, or a Screenwriter with **one-click installs** from our "Packs" library.
Powerful MCP Integration
We fully support the Model Context Protocol (MCP). Connect to any local or remote MCP server to give your AI direct access to your tools, databases, and internal APIs.
"If it speaks MCP, Tandem can use it."
The Open Alternative
You wouldn't let a stranger organize your physical desk; don't let a closed-source algorithm own your digital one.
Omnichannel Connections
Break out of the local sandbox. Connect Tandem seamlessly to external channels like Slack, Discord, and Telegram.
Manage persistent sessions and trigger workflows directly where your team collaborates.
Agentic Automation
Stop chatting and start delegating. Deploy specialized AI agents through the Agent Command Center to plan, execute, and verify complex tasks autonomously.
SEE TANDEM IN ACTION.
A beautiful, native interface designed for deep work. No complexity, just intelligence.
Smart Sidebar & Workspace Explorer
Tandem Coder Substrate
Full-lifecycle autonomous engineering. Run local triages, generate patches, draft PRs, and assess merge readiness directly via the Engine API.
Blackboard Coordination
Move beyond transcript inference. Tandem uses an engine-owned source of truth with a claim/lease model for concurrent multi-agent coordination.
Deterministic Runtime State
Structured task states with exact replay and checkpoints. Debug and audit autonomous work with per-step execution policies.
Headless Browser Automation
Native Chromium sidecar integration. Equip agents with memory-aware workflows to navigate and extract complex web payloads reliably.
Declarative V2 Workflows
Visual DAG node editor with automated cron scheduling, explicit MCP mappings, and programmable orchestration boundaries.
Memory-Aware Execution
Continuous workspace analysis that dedupes incidents with failure pattern memory and auto-emits regression signals.
THE LOCAL-FIRST
AI ENGINE.
Most AI tools require you to hand over your data to the cloud. Tandem breaks this cycle. Using strictly local processing or point-to-point encrypted connections, your workspace stays where it belongs: on your machine.
Zero Telemetry
We don't track what you do, what you say, or what you build.
Supervised Operations
The AI never executes commands without your explicit one-click approval.
Verifiably Open
100% Open Source. Audit the code yourself. No backdoors, no exceptions.
A KNOWLEDGE PACK FOR EVERY ROLE.
Native Power Packs bring specialized capabilities to every department, now with Tandem Coder Substrate, Browser Automation, and Declarative V2 visual builders.
Autonomous Engineering
Deploy Tandem Coder APIs to automatically manage PR drafting, issue patch implemention, and structured merge recommendations.
Quality Assurance
The new Bug Monitor continuously watches repositories, deduplicating recurrences using memory and drafting triage failure reports.
Web Data Operations
Supercharge automated tasks using Headless Chromium to click, navigate, snapshot, and extract complex unstructured web UI layouts.
Declarative V2 System
Build complex logic in an active DAG node editor. Supports automated schedule routing and explicit mapped MCP tools per operation.
Productivity & Standups
Setup reusable agent personalities to synthesize memory and deploy daily automatic workspace-aware standups for your team.
ChatOps Integrations
Manage sessions directly and naturally from Slack, Discord, and Telegram using semantic intents to create Packs or edit configs.
Enterprise Knowledge
Synthesize intelligence from vast document stores and manage comprehensive enterprise-grade knowledge source extraction pipelines.
Finance & Legal
Automate reconciliation, outline strict NDA reviews, and perform SOX testing with strict isolation and governance models.

"A mission to return power to the individual."
After many years contributing to open source code and using open source tools, I felt it was time to build something that solves a modern crisis: Privacy in the Age of Intelligence.
Tandem is my way of giving back. For the last two years, developers have had superpowers—automating tasks, generating code, and analyzing data. I built Tandem to give that exact same power to everyone else.
I wanted to take the raw potential of open source engineering and wrap it in a beautiful, completely visual interface that anyone can use. Zero coding required.
I only enjoy building apps that I will use and enjoy myself, so hopefully this brings joy and entertainment to others like it does for myself.
