# AI Agent Tools You Can Self-Host

> Source: https://theagentsindex.com/collections/ai-agent-tools-you-can-self-host (curated, quality-gated, re-verified)

Every listing in our index carries a `deployment` field, set to Cloud, Self-host or Both, researched and sourced the same way as pricing or license. 38 of the 126 current tools set it to Self-host or Both, meaning code and data can stay inside infrastructure you control instead of a vendor's cloud, at some price. See our full [deployment census](/blog/ai-agent-deployment-census-2026/) for the category-by-category breakdown this collection is drawn from.

This list is deliberately not the same set as our [open-source collection](/collections/open-source-ai-agent-tools/), even though the two overlap heavily. 25 of the 26 tools on that list are also here, because a clean open-source license almost always means you can run the code yourself. The single exception is Cartesia, whose Line SDK is Apache-2.0 but whose voice-agent runtime only ever executes on Cartesia's own infrastructure. But 13 more tools clear this list's bar without clearing that one: Mastra and OpenHands are open at the core but gate a separate hosted or enterprise layer (Mastra Cloud, OpenHands Cloud) behind its own paid tier; Warp open-sourced only its terminal client (dual AGPL-3.0/MIT since April 2026), while Warp Factories, the cloud-agent platform that actually runs and coordinates its agents, stays closed-source; n8n and Dify hedge their openness with a license condition their own docs tell you to check (fair-code, an Apache-2.0-derived license); and Claude Agent SDK, Factory, CodeRabbit, Bland AI, Deepgram Voice Agent API, Windsurf, Junie and Augment Code are closed-source products that still sell (or in Windsurf's case, ship free) a genuine private-deployment or local-execution path. If a compliance team's real question is "can this run inside our own network," the license badge alone answers it wrong for 13 of this list's 38 tools.

The category split is uneven in a way worth knowing before you shop by category page alone: agent frameworks are unanimous (15 of 16 offer some self-host path, since a framework you cannot run yourself is arguably not a framework), coding agents are the most genuinely mixed category (17 of 27): Junie's CLI and IDE plugin can point at a local model, but the JetBrains-run orchestration and credit metering behind it stay cloud-side, the same distinction our deployment census draws for Cartesia's speech models. Augment Code is the more straightforward case among this list's coding agents, with loops that can run in Augment's managed cloud or dispatch directly into a team's own AWS or GCP account. Support agents plus sales/marketing agents offer zero: every one of those 17 tools is cloud-only at any price, so a hard data-residency requirement in either category currently has no architectural answer on this site, only a contractual one (a vendor DPA or regional hosting commitment).

| Name | What it is | Why it's here | Pricing | API |
| --- | --- | --- | --- | --- |
| [LangChain](https://theagentsindex.com/langchain.md) | Open source agent frameworks plus LangSmith, the platform for tracing, evaluating and deploying agents. | No managed LangChain cloud product exists: MIT-licensed and self-hosted is the only way to run it, alongside the largest integration ecosystem of any framework here. | — | Yes |
| [CrewAI](https://theagentsindex.com/crewai.md) | Open-source multi-agent framework with a managed platform for deploying and governing agent workflows. | MIT-licensed with no managed CrewAI cloud offering: the orchestration layer runs entirely on your own infrastructure and model keys. | — | Yes |
| [AutoGen](https://theagentsindex.com/microsoft-autogen.md) | Microsoft's open-source Python framework for building single- and multi-agent applications; now in maintenance mode. | MIT-licensed research framework with no managed layer: Microsoft's own successor, Agent Framework, is the one in this category that also offers a hosted option. | — | Yes |
| [OpenAI Agents SDK (Python)](https://theagentsindex.com/openai-agents-sdk.md) | Open-source Python framework for building agents with tools, handoffs, guardrails, sandboxes and tracing. | MIT-licensed and self-host only: OpenAI does not offer a managed runtime for it, unlike Google ADK's Agent Runtime or Microsoft Agent Framework's Foundry layer. | — | Yes |
| [Pydantic AI](https://theagentsindex.com/pydantic-ai.md) | Typed Python agent framework: any model, any surface, with a harness for long-running coding and research agents. | MIT-licensed, Python-native, with no managed hosting layer from the Pydantic team: runs entirely inside a service you own. | — | Yes |
| [Cline](https://theagentsindex.com/cline.md) | Open-source coding agent for VS Code, JetBrains, the terminal and CI, running on whichever model you bring. | Apache-2.0 licensed with no cloud product to opt into: everything runs inside your own VS Code, JetBrains or terminal session. | — | Yes |
| [Aider](https://theagentsindex.com/aider.md) | Open-source terminal AI pair programmer that edits and commits code in your local git repo. | Apache-2.0, a local terminal process only: there is no Aider cloud tier at any price, so running it yourself is the only way it exists. | — | Yes |
| [Juggler](https://theagentsindex.com/juggler.md) | Visual workbench for AI coding agents: branching conversation trees, inspectable model transactions, local or remote. | AGPLv3 core with an Apache-2.0 extension SDK and no managed cloud version: the strongest copyleft license in this collection. | — | No |
| [OpenCode](https://theagentsindex.com/opencode.md) | Open source AI coding agent for the terminal, desktop, browser and IDE, running any model you connect. | MIT-licensed terminal agent with 188,976+ GitHub stars and no managed cloud counterpart: bring your own model key or a local model. | — | Yes |
| [zot](https://theagentsindex.com/zot.md) | Single-binary terminal coding agent harness in Go: five built-in tools, most providers, extensions in any language. | MIT-licensed, a single Go binary with no server component at all: the lightest self-hosting story in this collection. | — | Yes |
| [GPT Researcher](https://theagentsindex.com/gpt-researcher.md) | Open-source autonomous research agent that writes cited long-form reports from web and local sources. | Apache-2.0 licensed: the only self-hostable pick in the research-agents category; every other listed research agent here is cloud-only. | — | Yes |
| [Microsoft Agent Framework](https://theagentsindex.com/microsoft-agent-framework.md) | Open-source SDK for AI agents and multi-agent workflows across .NET, Python and Go. | MIT-licensed SDK for .NET and Python: self-host free, or use Microsoft's optional Foundry Hosted Agents managed layer on top. | — | Yes |
| [LlamaIndex](https://theagentsindex.com/llamaindex.md) | Open-source agent framework plus a credit-metered document parsing, extraction and indexing platform. | MIT-licensed core self-hosts free; the paid LlamaCloud layer adds managed parsing on top, entirely optional. | — | Yes |
| [LangGraph](https://theagentsindex.com/langgraph.md) | Open-source orchestration framework and runtime for stateful, long-running LLM agents, from LangChain. | MIT-licensed graph orchestration engine that self-hosts free; a separate, optional LangSmith platform adds deployment, tracing and evaluation on a metered basis, the same shape as LangChain's own optional LangSmith layer. It also clears the clean-license open-source collection's bar. | — | Yes |
| [Mastra](https://theagentsindex.com/mastra.md) | Open-source TypeScript framework for building AI agents, with a hosted platform for running and observing them. | Apache-2.0 core self-hosts free; a separate, optional Mastra Cloud platform adds hosting, a visual Studio and observability on a metered basis: open at the core, but that managed layer is why it sits outside the clean-license open-source collection. | — | Yes |
| [Letta](https://theagentsindex.com/letta.md) | Stateful agent harness, cloud and SDK for agents with persistent, git-versioned memory. | Apache-2.0 licensed with persistent memory: self-host free, or opt into managed Letta Cloud later without changing your integration code. | — | Yes |
| [Google Agent Development Kit (ADK)](https://theagentsindex.com/google-adk.md) | Open-source framework for building, evaluating and deploying AI agents in Python, TypeScript, Go, Java or Kotlin. | Apache-2.0 licensed across five language runtimes (Python, TypeScript, Go, Java, Kotlin): self-host anywhere, or use Google's own Agent Runtime managed layer on top. | — | Yes |
| [Agno](https://theagentsindex.com/agno.md) | Python SDK, open-source AgentOS runtime and hosted control plane for building and operating agents. | Apache-2.0 licensed, and there is no Agno-hosted alternative at any price: even the paid AgentOS production tier deploys into your own AWS, GCP, Railway or airgapped account rather than Agno's cloud. | — | Yes |
| [Claude Agent SDK](https://theagentsindex.com/claude-agent-sdk.md) | Python and TypeScript library that runs Claude Code's agent loop and tools inside your own application. | The wrapper package is MIT-licensed and the subprocess it spawns runs locally under your own control, but Anthropic's Commercial Terms of Service govern the SDK as a whole and the Claude Code binary it bundles isn't published as source: self-hostable in practice, just not on the clean-license open-source collection. | — | Yes |
| [Codex CLI](https://theagentsindex.com/codex-cli.md) | OpenAI's terminal coding agent for inspecting, editing and running repository code from the shell. | Apache-2.0 licensed CLI, free to self-host: OpenAI also offers a `codex cloud` managed alternative if you'd rather not run it yourself. | — | Yes |
| [OpenHands](https://theagentsindex.com/openhands.md) | Open-source software engineering agent with a browser client, CLI and Python SDK; local, cloud or self-hosted. | A free local OSS release (81,000+ GitHub stars) or a fully self-hosted enterprise deployment inside your own VPC: the hosted Cloud tier is the third, optional path, not the only one. | — | Yes |
| [Factory](https://theagentsindex.com/factory-ai.md) | Droid coding agents that run in the desktop app, CLI, IDEs, CI and Factory-managed cloud computers. | The Enterprise tier spans fully managed SaaS, a hybrid cloud/customer-compute split, full on-premise, or air-gapped deployment across AWS, Azure or GCP with customer-managed encryption keys: the deepest self-hosting spread of any closed-source listing here. | — | Yes |
| [CodeRabbit](https://theagentsindex.com/coderabbit.md) | AI code review across pull requests, IDE and CLI, with agentic fixes, pre-merge checks and security review. | The Enterprise tier adds self-hosting and API access on top of the default managed SaaS code-review product. | — | Yes |
| [Warp](https://theagentsindex.com/warp.md) | Agentic development environment: a terminal, a standalone agent CLI, and unattended cloud coding agents. | Open-sourced its terminal client under a dual AGPL-3.0/MIT license in April 2026, but Warp Factories (the cloud-agent platform that actually runs and coordinates agent work) stays closed and cloud-only; the self-hostable part is the terminal shell, not the agent backend. | — | Yes |
| [Zed](https://theagentsindex.com/zed.md) | Rust code editor with an Agent Panel running Zed's own agent, ACP external agents, or terminal agent CLIs. | GPL-3.0-or-later (Apache-2.0 for select components): a full IDE you can self-host and modify, not just a CLI wrapper. | — | No |
| [Devin Desktop](https://theagentsindex.com/windsurf.md) | AI IDE with a Kanban command center for running local and cloud coding agents; the renamed Windsurf. | The desktop IDE rebranded to Devin Desktop after Cognition's acquisition; a local execution mode runs the coding agent on your own machine instead of dispatching to Devin Cloud: a desktop-local mode, not a team-deployable server, so weigh it differently than the enterprise on-prem entries here. | — | Yes |
| [n8n](https://theagentsindex.com/n8n.md) | Workflow automation platform for building and running AI agents on a visual canvas, with code where needed. | Source-available (fair-code): self-host free with full functionality, or use n8n Cloud from €20/month; the license carries a condition worth reading before assuming it behaves like a no-strings open-source grant. | — | Yes |
| [Dify](https://theagentsindex.com/dify.md) | Open-source platform for building agentic workflows, AI agents and RAG knowledge pipelines. | Apache-2.0-derived core (149K+ GitHub stars): self-host with Docker for free, or use Dify's managed cloud; the built-in RAG pipeline runs the same either way. | — | Yes |
| [LiveKit Agents](https://theagentsindex.com/livekit-agents.md) | Open-source Python and Node.js framework for voice AI agents, with LiveKit Cloud hosting, telephony and observability. | Apache-2.0 licensed: the one clean open-source, self-hostable pick in an otherwise all-cloud voice-agents category. | — | Yes |
| [Bland](https://theagentsindex.com/bland-ai.md) | Enterprise voice AI platform for inbound and outbound phone agents, running on Bland's own self-hosted models. | The Enterprise tier adds dedicated infrastructure with self-hosted or on-premises deployment, US/EU/APAC data residency, and SOC 2/HIPAA/PCI DSS compliance: the only voice agent here with a private-deployment path; every other listed voice agent is cloud-only. | — | Yes |
| [Botpress](https://theagentsindex.com/botpress.md) | AI agent platform with a visual studio, a code-first TypeScript ADK and a helpdesk, priced per conversation. | The agent-platform entry you can actually run yourself: the core is MIT-licensed and free to self-host, with a managed cloud alongside it rather than instead of it. | — | Yes |
| [Deepgram Voice Agent API](https://theagentsindex.com/deepgram-voice-agent-api.md) | One WebSocket API that runs speech-to-text, LLM orchestration and text-to-speech for real-time voice agents. | The only closed-source platform here that still offers a real deployment choice: fully managed, VPC-hosted or fully self-hosted, backed by SOC 2 Type II and signed HIPAA BAAs. | — | Yes |
| [AgentsKit.js](https://theagentsindex.com/agentskit.md) | TypeScript foundation for AI agents: runtime, tools, memory, RAG, model adapters and headless chat UI bindings. | An MIT-licensed TypeScript library rather than a service: its own hosted layer, AgentsKit OS, is enterprise-only early access with no self-serve signup, so self-hosting remains the only way to actually run it today, with 50 built-in integrations and a 10KB zero-dependency core letting you point it at a local runtime as easily as a frontier API. | — | Yes |
| [Junie](https://theagentsindex.com/junie.md) | JetBrains' coding agent: runs in JetBrains IDEs, the terminal and CI, on JetBrains models or your own keys. | The only IDE-native agent here with a documented on-premise path: JetBrains includes Junie in AI Enterprise, which deploys cloud, on-premises or air-gapped. The isolated-infrastructure guide covers completion and Mellum rather than agent mode, so confirm Junie specifically before committing to an air-gapped rollout. | — | Yes |
| [OpenClaw](https://theagentsindex.com/openclaw.md) | Self-hosted gateway that connects chat apps like WhatsApp, Telegram and Slack to AI agents on your own machine. | The only agent-platform entry in this collection with no managed-cloud alternative at all: MIT-licensed, and it runs on your own machine or nowhere. | — | Yes |
| [Augment Code](https://theagentsindex.com/augment-code.md) | Cosmos platform running fleets of coding agents across the SDLC, plus Auggie CLI and IDE extensions. | Loops run in Augment's managed cloud, a team's own AWS or GCP account, laptops, or dev VMs: closed-source, but the own-account path is a genuine private-deployment option, not a roadmap promise. | — | Yes |
| [goose](https://theagentsindex.com/goose.md) | Open-source local AI agent — desktop app, CLI and ACP server — running on the LLM provider you bring. | Apache-2.0 licensed and stewarded by the Linux Foundation's Agentic AI Foundation: a Rust-built desktop app, CLI and embeddable API with no managed cloud counterpart, authenticating against 15+ LLM providers or an existing Claude, ChatGPT or Gemini subscription instead of a hosted account. | — | Yes |
| [Kilo Code](https://theagentsindex.com/kilo-code.md) | Open source AI coding agent for VS Code, JetBrains, CLI and cloud, with 500+ models at provider rates. | MIT-licensed end to end: extension, CLI and cloud-agent code all self-host; published pricing is Free Individual or $15/user/month Teams, with BYO API key or Kilo Pass credits from $19/month (Starter) to $199/month (Expert) plus a 5% processing fee on credit top-ups. | — | Yes |

## How this list is built

A tool earns a place here if its own Published, sourced listing sets its `deployment` field to Self-host or Both, verified against the vendor's own docs or pricing page describing an actual self-run, on-premise, air-gapped, or local-execution option, not a roadmap promise or a generic "enterprise-ready" claim. This is a deployment-location question, independent of license: an entry may be open-source with no managed layer at all, open-source with an optional paid cloud add-on, source-available under a fair-code or added-conditions license, or fully closed-source with a paid tier that still lets you keep data inside your own infrastructure. For the license-only question, see the [open-source collection](/collections/open-source-ai-agent-tools/); for the full category-by-category count, see the [deployment census](/blog/ai-agent-deployment-census-2026/) this collection is built from.
