# Prefect review (2026): is the free plan enough? > Python workflow orchestration with an open-source core and a cloud Checked Nov 13, 2026 ยท graded Nov 13, 2026 by ToolGPA. 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. - **Category:** Automation - **Made by:** Prefect Technologies, Inc. - **Website:** https://www.prefect.io - **Runs on:** Web - **Who should skip it:** Not for you if you don't write code, as workflows are Python functions. - **Facts last checked:** Nov 13, 2026 ## Pricing As of Nov 13, 2026, Prefect has a free plan, and paid plans start at $100 per month, billed monthly (Starter, 3 users). - **Pricing model:** Free plan - **Free plan:** Hobby plan: 2 users, up to 5 deployments, 500 minutes a month of Prefect Serverless and 7 days of run retention. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Hobby | $0 | 2 users, 5 deployments, 500 min/mo of Prefect Serverless, logging and alerting, 7-day run retention. | | Starter | $100 per month for up to 3 users, billed monthly | 20 deployments, 75 hours/mo of Prefect Serverless, bring your own compute, webhooks and 1,250 API requests/min. | | Team | $100 per user / month, for 4 to 8 users, billed monthly | 100 deployments, 225 hours/mo of Prefect Serverless, service accounts, 24-hour audit log, email support. | | Enterprise | Custom | SSO (SAML/OIDC), RBAC and ACLs, SCIM, multiple workspaces, unlimited deployments and a 99.9% uptime SLA. Annual billing; sold through sales. | Read from https://www.prefect.io/pricing on Nov 13, 2026. Prices change, so confirm with Prefect before buying. ## Ways to pay less - **Prefect Startup Program** (Startups): The pricing page says eligible startups get credits toward the Team plan through the Prefect Startup Program; qualification is by application. Source: https://www.prefect.io/pricing ## Key features - **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. ## 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. ## ToolGPA grades **GPA: 2.4 out of 4**, graded Nov 13, 2026. 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. - **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. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Prefect's own pages on 13 November 2026. Not based on using the product, and shorter than our full reviews. ## Where it stands among automation tools - 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. The category's chart of price against score: https://toolgpa.com/charts/automation ## Keep it, or make your own? **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. - You could not: Connections to other products, each kept working as those products change. - You could not: An AI agent, with the models and the safeguards behind it. - You could not: What a company asks for before it lets staff use something: SOC 2 and HIPAA. - You could not: The depth: we grade its features B, which means it covers the whole job. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
