New Episode of chatting with Prefect's Builders - @jlowin.dev chats with with @aaazzam.bsky.social about FastMCP's path from weekend project to the most popular open source thing we've built. Also: why "automation" is a better word than "orchestration." Hope you get outside today. Link below.

New podcast episode on MCP apps and what we're learning as this unfolds. The interesting question is where this goes next. We're recording these knowing things will shift and that's the point. Figure it out in public, see what sticks. Link below.

FastMCP 3.0 Beta is live 🚀 with a rebuild of the foundation. The foundation is rebuilt to move beyond simple tool scripts and into composable AI infrastructure. youtu.be/oN1xliDNWnQ?... 𝙼𝚊𝚓𝚘𝚛 𝚄𝚙𝚍𝚊𝚝𝚎𝚜 👇

FastMCP 3.0 is here! This is our largest and most ambitious release ever. We've re-architected the framework to support the next generation of MCP applications. It's time to move fast and make things. 🧵

Py AI DC brought out a phenomenal crowd last night, proof that the DC Python community is building the future of AI one meetup at a time. That's why we couldn't resist showing them Prefect ███████. This community got the first look before we let it loose on the world next week.

FastMCP v3 is coming. Jeremiah gives a sneak peek in this week's office hours, watch our latest podcast episode on YouTube below. Also: Py AI Conf Co-Hosted with @pydantic.dev March 10th, SF Guido van Rossum | @gvanrossum.bsky.social Sebastian Ramirez | @tiangolo.com Check it out at pyai.events

Use Celery or ARQ for background tasks? Check out github.com/chrisguidry/..., a simple to use and battle-tested background task system on Redis streams, written by @guid.foo

Travis Hoppe • Acting Chief AI Officer @ the CDC rounds out our guest speakers for our sold out Py AI DC. March 10 in SF: Py AI Conference is the big one. Only 300 spots to hear top-tier Python + AI speakers. The kind of lineup you book flights for. Both links in comments below.

The Py AI series is all about short talks, honest demos and real conversation. No one's selling you anything - just ideas you can take back to your project next day. Banjo Obayomi • @banjtheman.bsky.social • Senior Specialist Solutions Architect GenAI @ AWS joins us for Py AI DC.

Co-hosted with @pydantic.dev, Py AI is where people building with Python and AI actually talk about what they're working on. SF, NYC, London. Now it's DC's turn. Roni Kobrosly, Ph.D. • Director of Data Science @ Capital One kicks things off. More details dropping soon. RSVP in the comments.

We're having conversations with the team about building Prefect. Whatever comes up. This time with Engineers Nate Nowack (@zzstoatzz) and Alex Streed (@desertaxle). Designing for coding agents, the Prefect MCP server and the Pydantic AI integration. www.youtube.com/watch?v=qTT1...

Prefect is proud to be a founding member of the newly established Agentic AI Foundation!

Claude is a data engineer secretary now. The Prefect MCP server is now in beta - try it out! claude mcp add prefect -- uvx --from prefect-mcp prefect-mcp-server www.prefect.io/blog/a-prefe...

I'm teaming up with @sa.muelcolvin.com to launch a new meetup series, Py AI. Our first one is November 11 in San Francisco with talks from @pydantic.dev, @modal-labs.bsky.social, ReductoAI and @fastmcp.bsky.social. Hosted by our friends at pebblebed.com RSVP here: luma.com/gjtfecc7

Kudos again to the @prefect.io crew on doing documentation right for the AI era. I love everything about this -- mcp server, llms.txt and copy as markdown shortcut behavior

Prefect 3.4.17 is released! github.com/PrefectHQ/prefect/releases/tag/3.4.17 it includes several fixes and improvements related to background tasks [1] and multi-server setups [2] [1] docs.prefect.io/v3/advanced/background-tasks [2] docs.prefect.io/v3/advanced/self-hosted

🔥 FastMCP Cloud is here We built FastMCP to simplify MCP servers. Now deployment is instant too. Push repo → Live endpoint in <1min 📕 Learn about FastMCP Cloud-> prefect.io/blog/acceler... 🚀 Deploy for free -> fastmcp.cloud

happy OSS release day! prefect 3.4.14 is out now and includes: - a new process-pool task runner - a CLI command for migrating resources between backends and many more minor enhancements and bug fixes! github.com/PrefectHQ/pr...

How does a CLI command to transfer resources between backends relate to Kahn's algorithm and topological sorting? How can the looming threat of an LLM character takedown keep us accountable? These are questions that can only be answered in one place: dev-log.prefect.io

A week maintaining an active open-source project can make you laugh, cry, or reenable spacebar heating to avoid breaking changes. We're starting a dev log to share the good, the bad and the ugly decision making that goes into every week's release of Prefect: dev-log.prefect.io/so-a-dev-log...

Assets, made simple.

In 10 months, Prefect's open-source adoption has grown nearly 6x. This growth revealed a clear need: scaling teams needed options between Hobby and Enterprise tiers. Last month we added two new plans & the response's been 🔥 - we're smashing goals faster than we can set them!

In 10 months, Prefect's open-source adoption has grown nearly 6x. This growth revealed a clear need: scaling teams need options between our Hobby and Enterprise offerings. Today we're introducing two new plans, Starter and Team, designed to grow alongside our community.

🚀 Prefect's downloads are now 6x what they were just 10 months ago — from 300K/week to 1.8M/week. The excitement, feedback, and contributions from our community have been humbling. 🙇🙇🙇

Great piece by @cicdw.dev on Task Runners in @prefect.io. By decoupling the definition of what to execute from how to execute it, graduating from threads to @raydistributed is a line of code.

hear me out

We did it, @prefect.io

your friend using @prefect.io and the one stuck maintaining @apache-airflow.bsky.social

i'm not crying, you're crying

Ever wondered how to model topic 'trends' like Bluesky and others do? 📈 📉 I was curious too so I built a headline analytics pipeline which leverages a logistic growth model to do this! Orchestrated with @prefect.io and #dbt ⏳ 🔧 github.com/johnnyb1694/... #datascience #dataengineering #python

At @prefect.io

I am beyond excited to have a second day, three track developer focused Dev Day for @prefect.io Summit! On January 23rd, join us to get *hands on* My promise to you is that you'll leave with working code you can actually use rather than just cool keynotes (which are great...but code is better)

Launched another new @prefect.io “office” this week. I think this one might be popular.

Thanks to everyone who braved the rain to talk agent workflows and break in the new @prefect.io offices! Also huge thanks to the OpenAI API for going down right after my first example. Gotta love live demos.

🚀 @prefect.io

Genuinely, every week: “You work at Prefect? Huh, never heard of it.” “WAIT. YOU’RE THE MARVIN GUYS?” 🫠

Looking forward to delivering the @prefect.io workshop at @pydatasoton.bsky.social on Tuesday with @cfrohmaier.bsky.social - it should be a great session, plus there will be prizes! #datascience #dataengineering #python

Excited to start my new role as VP of Developer Relations at @prefect.io! 🚀 Looking forward to diving into the data space, where I believe the real winners in our AI-driven world will be those who unlock the full potential of their business data. Let’s build!

Stories like this make me wonder how many companies are just putting up with legacy products. Endpoint swapped Astronomer for @prefect.io. In the first 3 months, pipelines doubled and cost fell almost 75%. I don't know how you measure ROI, but that's a lot. Do more; spend less!

Here's a good summary of the key note I gave at @prefect.io summit this summer. - The Rise of Object Storage - The Great Database Decomposition - Postgres's Renaissance - The Promise and Challenge of Durable Execution

Amazing work by @sentry.io! I’m very proud that @prefect.io is a founding member of @opensourcepledge.com

Apparently @prefect.io hit #1 on GitHub Trending on Saturday and to be honest we can't figure out the catalyst. Still #4 today.

So @prefect.io is trending on GitHub, and for the love of me can’t find out why. Any guesses?
