Agency
Agency is a minimal, MIT-licensed Python framework for building multi-agent systems with local and AMQP messaging.
Agency is for people who want to own their agent messaging layer in plain Python, not rent one. The local space / AMQP space split is the part that earns its keep: prototype in-process, then move to a broker without rewriting your agents. The module set — agency.agent, agency.space, agency.spaces.local_space, agency.spaces.amqp_space — is small enough to read end to end, which is rare in this category. Pass if you want model connectors, dashboards, or retry logic handed to you; Agency deliberately ships none of that, and you would be writing them yourself.

Skip Agency if you want model connectors, a dashboard, or retry and monitoring logic included, rather than a messaging layer you write and operate yourself.
Distributed deployments mean running and paying for your own AMQP broker infrastructure — Agency bundles no hosting.
Agency is published as an MIT-licensed open-source Python framework, so the direct cost is zero; the real budget line is the engineering time to build model connectors, retries, caching and monitoring yourself, plus broker hosting once you move off the local space to the AMQP space.

About Agency
Agency is a minimal, MIT-licensed Python framework for developers who want autonomous agents exchanging messages without an orchestration layer sitting in between. The core idea stays simple and out of your way: you define agents as Python classes, attach actions to them, and connect them through communication spaces. Two spaces ship with the framework. The local space handles in-process messaging between agents running in the same Python program, while the AMQP space moves messages through a broker so agents can run distributed across machines. Both asynchronous fire-and-forget messaging and synchronous request-response calls work in the same system, so a loose task hand-off and a blocking agent call can coexist. Around that messaging core, Agency bundles focused utilities rather than opinions. Lifecycle hooks via on_start and on_stop, audit logging through agency.logger, resource management with agency.resources, schema definitions in agency.schema, an agent queue (agency.queue) and a processor (agency.processor). The site pairs a module-by-module API reference with an example application walkthrough, which is the honest on-ramp if you're new to the codebase. That scope is deliberate. Agency is aimed at AI/ML engineers, researchers, hobbyists and educators who are comfortable writing their own retries, caching and monitoring, and who would rather read every line of their messaging layer than inherit someone else's abstractions. If you need prebuilt model connectors, a dashboard, or managed hosting, look at the larger agent platforms instead, or pair Agency with the pieces you already trust.
Behind the Verdict
Agency sits in the small corner of the agent-tooling market that assumes you are a competent Python engineer who wants a messaging substrate, not an opinionated platform. Strengths. The abstraction is thin and legible. You subclass an agent, define actions, and drop it into a space. Two space implementations cover the common arc of a project: agency.spaces.local_space keeps everything in-process for tight iteration, and agency.spaces.amqp_space pushes the same messages through a broker so agents can live on separate machines. Both async fire-and-forget and synchronous request-response messaging are supported in the same system, so you are not forced to pick a topology up front. Lifecycle callbacks (on_start, on_stop), agency.logger for audit logging, agency.resources for resource handling, agency.schema for schema definitions, and agency.queue / agency.processor round out the toolkit without adding opinions about how your agents should think. The MIT license is genuinely permissive, which matters if you intend to embed this in something you ship. Weaknesses. The framework stops at the messaging boundary. There are no LLM or model connectors in the box — wiring an agent to a model provider is work you write and then maintain. Caching, retries, error recovery, and monitoring are all yours to build; nothing in the module list handles them. Documentation is the API reference plus the example application walkthrough, which is enough to get oriented but is not a production deployment guide. There is no graphical interface and no hosted option, so the operational surface — brokers, observability, alerting — belongs to you. Where it fits. Prototypes and research codebases where the agent coordination pattern is the interesting part and you want to see all of it. Classroom and conference demos, because the code is readable and the local space means no infrastructure to stand up. Teams planning a deliberate path from a single-process prototype to a broker-backed distributed layout without rewriting their agents. Where it doesn't. Anyone who wants a no-code builder, a dashboard, managed hosting, or prebuilt model integrations. Production systems that need audit-ready logging, alerting, or SLAs out of the box. And anyone who does not want to operate an AMQP broker when the local space stops being enough.

Real-world workflow fit
Concrete scenarios for the personas Agency actually fits — and what changes day-one when you adopt it.
You define agents as Python classes, attach actions, and wire them together in agency.spaces.local_space so every message stays in-process while you iterate on the coordination pattern.
Outcome: A running multi-agent loop with no broker or cloud account to configure, and code you can read end to end.
You swap the local space for agency.spaces.amqp_space so the same agents communicate through a broker across machines, leaving your agent classes and actions unchanged.
Outcome: The prototype scales out without a rewrite of the agent logic — only the space and the broker infrastructure change.
You use the example application walkthrough alongside the module reference so students can trace an agent from definition through lifecycle callbacks (on_start, on_stop) and messaging.
Outcome: Students read the messaging layer directly rather than trusting a black box, using only the pip-installed framework.
Use Cases
- Build a multi-agent chat system where agents delegate tasks to each other
- Create a research assistant that queries APIs and summarizes results across agents
- Prototype a personal assistant that manages calendar and email through specialized agents
- Demo agent coordination patterns for a conference talk or classroom
- Experiment with async versus synchronous messaging topologies before committing
- Scale an in-process agent prototype out to a broker-backed distributed setup
Limitations
- Agency is a focused messaging framework, and the gaps mirror that focus.
- No LLM API integrations ship with it, so connecting to a model provider is manual work you write and maintain.
- Documentation is limited to the API reference and the example application walkthrough — there is not a deep guide path for production deployment.
- There is no graphical interface, so visibility into running agents is something you build.
- Caching, error recovery, retries, and monitoring must be built on top; nothing in the toolkit handles them for you.
- If you need audit-ready logging, alerting, or SLAs out of the box, this framework will not provide them.
- Running the AMQP space distributed also means operating a broker.

Where the pricing makes sense
The company stage and team size where Agency's pricing actually pencils out — and where peers do it cheaper.
Agency is published as an MIT-licensed open-source Python framework, so the direct cost is zero; the real budget line is the engineering time to build model connectors, retries, caching and monitoring yourself, plus broker hosting once you move off the local space to the AMQP space.
Setup time & first value
How long it actually takes to get something useful out of Agency — broken out by persona, not the marketing-page minute.
Python developers comfortable with async code: minutes to pip-install and get agents talking in agency.spaces.local_space, since nothing external is required. Researchers targeting distribution: add an AMQP broker and configuration before the same agents run across machines. Educators: the example application walkthrough is the fastest route to a working demo for a class.
Switching to or from Agency
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a hand-rolled asyncio message bus: reimplement your handlers as agent actions and register them in a space instead of a custom dispatch loop.
- →From a heavier agent platform: keep your model calls as agent actions and let Agency handle only the messaging and lifecycle layer.
- →From a monolithic agent script: split responsibilities into several agents and connect them through agency.spaces.local_space before distributing.
- ↗To a managed agent platform: your agent logic is plain Python, so port the actions and drop the space and lifecycle wiring.
- ↗To a custom in-house bus: Agency's agent classes and actions are ordinary Python objects you can lift onto your own transport.
- ↗To a different messaging framework: the local/AMQP space abstraction maps onto most broker-backed transports, so the rewrite is mostly the space layer.
