Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 90 of the 134 other automation tools we grade
Prefect is a workflow orchestration framework for Python. A decorator turns an ordinary function into a flow with retries, scheduling and run tracking, and the same code runs on the open-source server or on Prefect Cloud. The cloud adds hosted compute, alerting, service accounts and governance features across four plans.
To get you started, here are 9 things to know about Prefect, taken from its own pages and our grades.
You write Python and set up work pools, or self-host the server.
- 1
Best for Python teams scheduling and tracking workflows
Prefect turns an ordinary Python function into a scheduled, retried and tracked workflow, on an open-source server or on Prefect Cloud.
- 2
Paid plans start at $100 a month
As its pricing page puts it: $100 per month, billed monthly (Starter, 3 users).
- 3
There is a free plan
Hobby plan: 2 users, up to 5 deployments, 500 minutes a month of Prefect Serverless and 7 days of run retention.
- 4
It runs on Web
Web.
- 5
Flows from plain Python
Adding a decorator to a Python function makes it a flow with retries, state tracking and artifacts, without a separate DAG definition language.
- 6
Scheduling and deployments
Flows are packaged as deployments that can be scheduled, triggered by webhooks or events, and run remotely on work pools you configure.
- 7
Prefect Serverless
Managed compute run by Prefect, so flows can run without hosting your own infrastructure. Each paid plan includes a monthly allowance of it.
- 8
A 2.4 GPA, above 90 of 134
That is against the other automation tools we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Prefect you would be making connections to other products, each kept working as those products change. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for Python teams scheduling and tracking workflows
Prefect turns an ordinary Python function into a scheduled, retried and tracked workflow, on an open-source server or on Prefect Cloud. The free Hobby plan stops at 2 users and 5 deployments, the cheapest Team bill is $400 a month, and it needs people who write Python.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | The open-source version is free to host yourself, which needs a server. Paid Cloud starts at $100 a month for 3 users, against a $19.99 middle for automation tools. |
| Free plan and trial | B | A free Hobby plan: 2 users, 5 deployments, 500 minutes a month of serverless compute and 7 days of run retention. One person can live on that. |
| Features | B | Flows, scheduling, remote runs, managed compute, alerting and automations. SSO, SCIM and an SLA are Enterprise only, which the listing treats as plan gating. |
| Ease of use | D | No store rating on record. You write Python and set up work pools, or self-host the server. |
| Platforms and integrations | B | Web, an API and integrations with AWS, Databricks, dbt, Docker, Kubernetes, Slack, Snowflake and GitHub. No desktop or phone app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Prefect is for
- Fits if you write Python and want scheduling, retries and run history
- Makes sense if you want an open-source core you can self-host
Who it is not for
- Not for you if you don't write code, as workflows are Python functions
- Tight if you grow past Hobby: 2 users, 5 deployments and 7 days of run history
- Pricey if you need Team: it starts at 4 users at $100 each, so $400 a month
- Watch out: SSO, SCIM, RBAC and an uptime SLA are Enterprise only
- Watch out: there is no free trial of paid plans, the Hobby plan stands in for it
Good to know
Good for
- Python data and ML teams moving scripts into scheduled, monitored workflows
- Small teams that want a hosted control plane without a per-run price
- Teams that want to start self-hosted and move to a managed cloud later
Worth knowing
- The Hobby plan stops at 2 users, 5 deployments and 7 days of run retention.
- Team starts at 4 users at $100 per user per month, so the cheapest Team bill is $400 a month.
- SSO, SCIM, object-level RBAC and an uptime SLA are Enterprise-only; Starter and Team have no SLA.
- The pricing page says it offers no free trial of paid plans; the Hobby plan serves that purpose.

Part 03 · Features
What it does
Its main features, where it runs, what it works with and who makes it
1
Place it runs: Web
Python workflow orchestration with an open-source core and a cloud. Here is what it does, as its own site describes it, and what it covers: open source, self-hostable, public API, workflow automation, AI agents.
Flows, scheduling, remote runs, managed compute, alerting and automations.
- Flows from plain Python
- Adding a decorator to a Python function makes it a flow with retries, state tracking and artifacts, without a separate DAG definition language.
- Scheduling and deployments
- Flows are packaged as deployments that can be scheduled, triggered by webhooks or events, and run remotely on work pools you configure.
- Prefect Serverless
- Managed compute run by Prefect, so flows can run without hosting your own infrastructure. Each paid plan includes a monthly allowance of it.
- Observability and automations
- Run logs, alerting and event-driven automations that send notifications or trigger runs when something in a workflow changes state.
- Open-source core
- The orchestration framework is open source and can be self-hosted; Prefect Cloud is the hosted version with more governance and scale features.
- Security and compliance
- Prefect states SOC 2 Type II, HIPAA and GDPR alignment, with hybrid and VPC deployment options on higher plans.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
90/134
Other automation tools it is graded above
Prefect's GPA of 2.4 is higher than 90 of the 134 other automation tools we grade, and level with 23.
It stands best on free plan and trial (B, above 100 of 134) and worst on ease of use (D, above 0).
Its paid plans start at $100 a month, against a middle price of $22.17 for the category: 54 of the 65 others that charge start lower.
On features, ease of use and platforms it scores 2.3 out of 4. 18 tools score higher and cost less.
Each grade against the category
Every bar is all 135 automation tools we grade, cut by the letter each got. Prefect’s own letter is outlined.

Price against what you get
Each dot is one of 80 automation tools. Further left costs less; higher up scores better on features, ease of use and platforms. Prefect is the marked dot.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Prefect you would be making connections to other products, each kept working as those products change. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 2.4 is higher than 90 of the 134 other automation tools we grade. It costs $1,200 a year. Prefect is open source, so there is a third way: take its code and run it yourself.
What you could not
- Connections to other products, each kept working as those products change.
- An AI agent, with the models and the safeguards behind it.
- What a company asks for before it lets staff use something: SOC 2 and HIPAA.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Prefect’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
