Build an assistant around your own tools.

Agent Zero is for technical users who want a configurable assistant and can maintain its computer environment. Free app; some AI features or models cost extra.

Getting started: TechnicalInstall the launcher and its computer environment, connect a model, then review files, tools, permissions and backups. Our setup guide, not a performance score.

A real example to picture

Agent Zero’s writing guide describes improving a draft and explaining the changes. Start with a harmless sample, compare the result with the original and review any facts it adds. This does not require giving access to a personal inbox.

Provider example, not our own test. See the provider’s explanation

A first task to try.

Start small, give it the right context and review what comes back.

Suggested test · not yet tested

Improve a harmless draft

Try one short editing task before enabling more tools.

Try this task

You’ll need: A working Agent Zero instance, model access and a harmless text sample.
Our starter prompt: Rewrite this short sample in plain English. Keep its facts, explain the main changes and list any uncertainty. Use only the text I paste. Do not run commands, open accounts, send messages or publish anything.
What to expect: An edited sample with a short explanation you can check.
How to check it is done: Compare the rewrite with the supplied text and confirm it added no facts. Nothing should be published or sent.

Our suggested test, not a tested result. Model charges can apply. No valuable files or connected accounts needed.

More things to try with Agent Zero

What Agent Zero can do.

Technical users who want a configurable assistant and can maintain its computer environment.

Work with a chosen model

Use a supported hosted provider or a compatible local model setup.

Use selected tools and files

Configure the environment and permissions for the task. Host access is a deliberate extra step.

Shape your own workflow

Customize tools, instructions and memory instead of relying on one fixed assistant.

Agent Zero pricing.

Free softwareModel usage and running costs are separate

Free software: The framework has an ongoing MIT software license. This is not a hosted AI service with a free model allowance.
Free trial: The framework needs no software trial. Separate model providers set their own trial credits, card requirements, quotas and renewal rules.
Paid plans: No fixed Agent Zero software subscription, annual invoice or complete monthly running price was confirmed. Choose a model provider and local or remote computer resources separately.
Extra costs & limits: Main, utility and embedding models can have provider costs. Remote hosting, local hardware and optional tools are separate. Optional platform/API offerings are not bundled into this software listing.

Prices in USD unless noted. Check the billing period; local prices, taxes and offers can differ.

Model usage

Depends on your provider

Choose a supported model service or local model runtime. Provider quotas, credits, card rules and renewals belong to that separate service.

Local or hosted computer

Your own costs

Local models need suitable hardware. A remote server, hosting and optional tools can add charges. No universal monthly total was confirmed.

Trials and subscriptions

No framework trial required

The software license is ongoing. No general hosted-service free allowance, paid Agent Zero subscription or annual invoice is included in this software listing.

Install the launcher and its computer environment, connect a model, then review files, tools, permissions and backups.

Install the official launcher and complete its computer-environment setup.
Choose the model provider and check its actual charges. Start with harmless sample material.
Keep permissions narrow, review commands and results, and set up backups before using valuable files.

Apps, extensions & calls

Apps & services

Model providers, approved files, local tools and optional host browser

Hosted model serviceAccount connection: Connect a supported model provider. Its account permissions, usage charges and quotas are separate from the free framework.
Model configuration
Local model runtimeComputer access: Run a compatible model server on suitable hardware and connect the instance to it. This is a local setup, not a provider-account subscription.
Local model setup
Instance files and toolsComputer access: The agent works in its configured computer environment. Check file and command access.
Framework capabilities
Optional host accessComputer access: A0 CLI can give access to your own computer’s files, terminal and browser. Review each permission; this is separate from the default instance.
Host access setup

Selected connection options checked 20 Oct 2026. Not hands-on tests.

Voice & calls

The reviewed sources do not establish a general live voice conversation or ordinary telephone-calling service.

Availability & things to know

The launcher supports Windows, macOS and Linux. It uses a container environment or a remote instance. Access to your host files, terminal and browser is an optional extra setup.

Treat an instance as one trust boundary. Keep unrelated sensitive projects separate; the linked open issue reports a project-isolation problem. No framework or model account was installed or connected for this review.

Free software does not include model usage or hosting. Host access can reach real files and browser accounts. A public issue reports cross-project credential access; it is a user report, not our verified finding. Do not assume projects on one instance isolate secrets.

Public community usage reports. Current repository reports describe people running Docker installations, scheduled work and image/file conversations. They establish a technical user audience and expose limitations. Bug reports are not success benchmarks, and we have not reproduced these workflows.

The official site names Agent Zero, s.r.o. and a Brno address; the software license names the same operator. This is separate from contributors, model-provider locations and hosting.
