H Company vs Amazon Nova Act (2026): which should you pick?

Pick H Company if

• Fits if you build agents that drive a browser or desktop through an API
• Works for developers who want open weights as well as a hosted option

Look elsewhere if

• Watch out: session counts are approximate and vary with task complexity and model
• Pricey if you go over: Builder and Startup top-ups cost model cost plus 20%
• Skip it if you want no-code, as the tools are an API, models and a CLI
• Tight if you need the Startup plan at $200 a month for more volume

Pick Amazon Nova Act if

• Fits if you already build on AWS and write Python
• Works for developers who want browser tasks that can hand off to a human

Look elsewhere if

• Not for you if you want no-code, as it needs code and an AWS account
• Watch out: the documentation lists a single supported Region, US East (N. Virginia)
• Pricey if you run many agents: each parallel agent is billed on its own at $4.75 an hour
• Skip it if you want a free try, as none is listed

H Company

• Session counts are approximate; the page says they vary with task complexity and models used.
• Past the included amount, Builder and Startup top-ups cost model cost plus 20%.
• Per-token Models API rates were not readable on the pricing page text and are not listed here.

Amazon Nova Act

• The documentation lists a single supported AWS Region, US East (N. Virginia).
• Billing is by agent hour, so cost depends on how long workflows run; each parallel agent is billed on its own.
• It needs an AWS account and code; there is no no-code builder on the pages read.

H Company

Agents API

Agents work in a cloud-hosted browser or on a desktop without needing site APIs, and are reachable through an API, SDK, MCP server or CLI.

Models API

An OpenAI-compatible API for the Holo multimodal models, taking text and image input, so you can run your own agent loop.

Open weights

Holo model checkpoints can be downloaded from Hugging Face and run on your own hardware.

HoloTab and HoloDesktop CLI

HoloTab is an AI browser companion on the Chrome Web Store, and the HoloDesktop CLI runs the agent on-device.

Enterprise deployment

Forward deployed engineers build custom agents on a customer's existing systems. The site lists SOC 2 Type II, ISO 27001 and GDPR compliance.

Amazon Nova Act

Natural language plus Python

Each act() call passes a plain-language task to the model inside a session, and the surrounding script is ordinary Python.

Browser workflow automation

Listed uses include data entry into web forms, extracting fields from sites and dashboards, and running QA test cases in the browser.

Human-in-the-loop

An agent can escalate to a human supervisor when appropriate, and the waiting time is not billed.

Tools and APIs

Agents can call APIs and remote MCP tools, or use other agent frameworks, alongside the browser.

AWS deployment and monitoring

Native integration with Amazon Bedrock AgentCore for deployment, CloudWatch for monitoring and IAM for permissions.
