AI Agent Host

AI Agent Host is an open-source, modular development environment from Quantiota that packages the essential infrastructure for building, testing, and observing LangChain-based AI agents into a single Docker Compose stack. Rather than requiring developers to manually wire together a database, visualization layer, IDE, and agent runtime, AI Agent Host ships these components pre-configured so engineers and researchers can focus on agent logic, prompt engineering, and behavioral experimentation rather than DevOps plumbing.

At the core of the stack is QuestDB, a high-performance time-series database optimized for ingesting and querying large volumes of timestamped data. This makes it well suited for agent telemetry use cases such as logging tool calls, tracking decision latencies, recording market-data ticks for trading agents, or storing event streams produced by autonomous workflows. Grafana sits alongside QuestDB to provide rich, real-time dashboards over agent activity, allowing developers to visualize behavior, performance metrics, and outcomes without writing custom UI code. Code-Server, a browser-based VS Code, is bundled so users can edit, run, and debug agent code from any device with a browser, which is particularly useful for cloud-hosted or remote setups.

AI Agent Host explicitly targets LangChain workflows and integrates with Claude Code to enable agentic development loops in which an LLM can read repository state, propose changes, run experiments, and iterate. The combined toolkit supports research scenarios such as quantitative trading agents, multi-agent system experiments, RAG pipelines that need persistent state, and reinforcement-style feedback loops where agent actions and outcomes must be persisted and reviewed. Because everything is containerized, the environment can be reproduced across local laptops, on-premise servers, or VPS instances, making collaborative experimentation easier and helping teams avoid the classic 'works on my machine' problem.

The project is community-maintained on GitHub under the Quantiota organization and is intended for developers comfortable with Docker, Linux, and self-hosting. It is not a managed SaaS — there is no hosted control plane, billing layer, or commercial support — so adopters take on the responsibility of provisioning hardware, securing exposed services, and keeping component images up to date. In exchange, they get a transparent, free, and extensible foundation that can be customized to specific agent research needs without vendor lock-in.
