Agentor

Agentor is an open-source Python framework for long-running AI agents with durable, forkable runs and A2A serving.

68/100MonitorFreeFree

If your agents die mid-run and you've written the same retry-and-resume scaffolding twice, Agentor's durable, forkable runs and one-line agent.serve() for A2A are worth a serious look. The provider list means no lock-in to a single model vendor. Just budget for the 0.1.0 reality: a young API and persistence you operate yourself, not a hosted service.

Skip it if

Skip Agentor if you want a no-code builder or a hosted agent dashboard where someone else owns uptime, tracing and crash recovery instead of you operating durable run state on your own infrastructure in Python.

Skip-it-if note generated
The 30-second take
Biggest gripe

The bundled GetWeatherTool() reads a free WeatherAPI.com key from the WEATHER_API_KEY environment variable and raises if it is not set, so you register for and manage that key yourself

Price reality

Agentor is an open-source framework you install with `pip install agentor` at no licence cost, so the real budget is engineering time plus your own provider and infrastructure spend. Against hosted options such as LangGraph Cloud, that makes it materially cheaper on subscription line items and materially more expensive on the hours your team spends operating durable run state; the docs' example model string is "gpt-5-mini" pulled through your own provider account.

Agentor is an open-source Python framework for building, deploying and operating long-running AI agents with tool use, MCP support and the A2A protocol. There's no canvas to drag boxes around on: you construct an Agentor instance with a name, a model string and a list of tools, call agent.run() for a result, and call agent.serve() to publish the agent over A2A so other agents can discover and call it. The docs' quick example wires GetWeatherTool() against a free WeatherAPI.com key read from WEATHER_API_KEY. Durable execution is the center of gravity. Every step of a run is saved, which means a second process can finish the work after a crash instead of starting over, and you can fork a saved run into a new branch rather than replaying history. Model access stays provider-neutral — point it at OpenRouter, Groq, Together, vLLM, Ollama, or your own OpenAI-compatible server, with your own credentials. Beyond the core loop, Agentor covers the plumbing a production agent needs: custom tool authoring, MCP servers including ones with authorization, tool search, streaming responses, a skills system for packaging capabilities into reusable modules, and tracing for monitoring live runs. Agents can be mounted into a FastAPI APIRouter, and there are guides for SuperAuth setup plus Gmail and Google Calendar integration. Agentor 0.1.0 is the current stable release, installed with pip install agentor on the project's own agent engine. Against managed orchestration like LangGraph Cloud, it trades turnkey hosting for a self-hostable core you control. That's a good trade if your agents have to survive restarts and speak across protocols; a poor one if you'd rather someone else own uptime and you want a frozen API surface.

Key features

  • Durable execution: every run step saved so another process can finish it after a crash
  • Fork a saved run into a new branch instead of replaying from the start
  • agent.serve() enables the A2A protocol for agent discovery and interoperability
  • agent.run() returns structured output
  • Streaming responses for interactive agent use cases
  • Custom tool authoring, including the bundled GetWeatherTool example
  • MCP server support, including MCP servers with authorization
  • Tool search across available tools
  • Model providers: OpenRouter, Groq, Together, vLLM, Ollama, or your own OpenAI-compatible server
  • Skills system for modular, reusable agent capabilities
  • Tracing and monitoring for production agents
  • Integrate agents with a FastAPI APIRouter
  • Gmail and Google Calendar integration guides
  • SuperAuth setup guide

Behind the verdict

Most Python agent frameworks assume a request-response shape: prompt in, answer out, forget. Agentor assumes the opposite — that runs are long, that processes crash, and that you'll want to branch from step 47 rather than pay for steps 1 through 46 again. We'd reach for it specifically when that assumption matches your workload: research agents that grind for hours, multi-stage pipelines that call external APIs with side effects, anything where a restart shouldn't mean a re-bill. Pick it if you're a Python team comfortable owning infrastructure and you want agent-to-agent interoperability without adopting a vendor's runtime. The A2A story is unusually cheap here — agent.serve() makes an agent discoverable, which matters if you're building a mesh of specialists rather than one monolith. Provider-neutrality is the other draw: swap OpenRouter for a local vLLM box in an afternoon, credentials stay yours. Pass if you want a dashboard, a managed control plane, or a support contract. Also pass for short request-response bots: durable run state is overhead you'll pay for and never use. Non-Python teams and anyone expecting a no-code builder are outside the target. Where it bites in practice: 0.1.0 means breaking changes are a when, not an if — pin your version and read changelogs before upgrading. Persistence is a primitive you operate, so plan for where run state lives and how you clean it up; a crash-safe run store you configure badly is just a slower failure. Docs are thorough but Mintlify-hosted and moving, with an August 25, 2026 revision. The closest alternative is LangGraph Cloud — same durable-graph instinct, but managed, with a polished UI and support behind it. Choose Agentor when self-hosting and protocol openness beat convenience; choose managed orchestration

Limitations

  • Agentor is an open-source Python framework, so building and deploying agents requires programming skill and running your own environment via `pip install agentor`.
  • The current stable release is 0.1.0, which means a young API surface; durable run persistence and crash recovery are primitives you operate, not a hosted service.
  • It runs on Agentor's own agent engine and supports any OpenAI-compatible provider, so you supply your own provider credentials and infrastructure.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • The bundled GetWeatherTool() reads a free WeatherAPI.com key from the WEATHER_API_KEY environment variable and raises if it is not set, so you register for and manage that key yourself
  • You bring your own model provider credentials for OpenRouter, Groq, Together, vLLM or Ollama, and any usage charges on those providers land on your account, not Agentor's
  • Durable run state has to be persisted somewhere you operate and pay for, since crash recovery and run forking are framework primitives rather than a hosted service
  • Running the Celesto CLI for cloud deployment means a second environment to keep configured alongside your local `pip install agentor` setup
  • Tracing production runs is built in, but the storage and observability backend for those traces is infrastructure you supply and maintain

Where the pricing makes sense

The company stage and team size where Agentor's pricing actually pencils out — and where peers do it cheaper.

Agentor is an open-source framework you install with `pip install agentor` at no licence cost, so the real budget is engineering time plus your own provider and infrastructure spend. Against hosted options such as LangGraph Cloud, that makes it materially cheaper on subscription line items and materially more expensive on the hours your team spends operating durable run state; the docs' example model string is "gpt-5-mini" pulled through your own provider account.

Real-world workflow fit

Concrete scenarios for the personas Agentor actually fits — and what changes day-one when you adopt it.

Backend Python developer

Installs Agentor with `pip install agentor`, sets provider credentials, builds an Agentor instance with the model string "gpt-5-mini" and GetWeatherTool(), then calls agent.run() for a structured result before calling agent.serve() to expose the agent over A2A.

Outcome: A working, discoverable agent in a single file, with no orchestration vendor in the request path.

Platform integrator

Writes an MCP server with authorization, wires the agent into a FastAPI APIRouter, and lets a crashed run be finished by a second process or forked into a new branch to try a different tool path.

Outcome: Multi-system workflows that keep their state across restarts instead of replaying prior steps.

Self-hosting engineer with data-residency constraints

Points the same agent code at a local Ollama or vLLM instance rather than a hosted provider, then follows the tracing guide to monitor production runs for slow or failing tool calls.

Outcome: Model traffic stays inside the network while run-level observability still works.

Workflow scenarios generated

Use cases

  • Build a long-running support agent that calls MCP tools to reach databases and survives a process crash mid-run
  • Deploy several agents that discover and call each other over the A2A protocol for multi-system workflows
  • Create a personal assistant that schedules meetings through the documented Gmail and Google Calendar guides
  • Embed an Agentor agent in a FastAPI app to stream responses to end users
  • Fork a partially completed run into a new branch to try a different tool path without redoing prior steps
  • Run an agent against a local Ollama or vLLM model when data cannot leave your network
  • Package a repeatable capability as a skill and reuse it across multiple agents
  • Trace agent runs in production to see which tool calls are slow or failing

Setup time & first value

How long it actually takes to get something useful out of Agentor — broken out by persona, not the marketing-page minute.

A developer with Python and provider credentials in hand can follow the Quickstart — `pip install agentor`, configure credentials, run the Weather Agent example — and have a working agent in minutes, or less than an hour including a weather API key. Getting durable run persistence and a FastAPI-hosted, A2A-served agent production-ready is a day or more of your own work, since none of that is a

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • →From LangGraph or a custom Python agent loop: port the graph nodes into Agentor tools and use durable runs for checkpointing instead of your own persistence layer.
  • →From a no-code agent builder: rewrite the assembled flow as Python using custom tools and the skills system to package reusable capabilities.
  • →From raw OpenAI-compatible client code: wrap the calls in an Agentor instance and keep the same provider endpoint, since Agentor accepts any OpenAI-compatible server.
  • →From a single-agent script: add agent.serve() to expose the existing agent over A2A so other agents can discover and call it.
Migrating out
  • ↗To LangGraph Cloud: rebuild the orchestration graph and hand durable run state and uptime to a managed control plane.
  • ↗To AutoGen: re-express your agents as conversational agents if multi-agent chat is a better fit than A2A discovery.
  • ↗To a narrower OpenAI-compatible client setup: drop the framework and call your provider directly if you no longer need durable runs or agent-to-agent serving.
  • ↗To a hosted agent platform: move tracing, persistence and crash recovery off your own infrastructure if operating them is no longer worth the engineering time.
