38 of the 214 tools in our index can run somewhere you control. This is a deployment question, not a license one: the list mixes MIT- and Apache-2.0-licensed frameworks with no managed cloud at all, open cores paired with optional paid hosted layers, fair-code and source-available builds, and a handful of closed-source products that still ship a real private-deployment path.

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 214 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.

What this collection covers

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 32): 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).

What it takes to be on this list

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.
