Heroku is transitioning to a sustaining engineering model focused on stability, security, reliability, and support. Heroku remains an actively supported, production-ready platform, with an emphasis on maintaining quality and operational excellence rather than introducing new features. We know changes like this can raise questions, and we want to be clear about what this means for customers. There is no change for customers using Heroku today. Customers who pay via credit card in the Heroku dashboard—both existing and new—can continue to use Heroku with no changes to pricing, billing, service, or day-to-day usage. Core platform functionality, including applications, pipelines, teams, and add-ons, is unaffected, and customers can continue to rely on Heroku for their production, business-critical workloads. Enterprise Account contracts will no longer be offered to new customers. Existing Enterprise subscriptions and support contracts will continue to be fully honored and may renew as usual. Why this change We’re focusing our product and engineering investments on areas where we can deliver the greatest long-term customer value, including helping organizations build and deploy enterprise-grade AI in a secure and trusted way.

We've spent 7 years building the data notebook for AI era. Today, we're open sourcing it. Deepnote Open Source is successor to the Jupyter notebook. It acts as a drop-in replacement for Jupyter with an AI-first design, sleek UI, new blocks, and native data integrations. Use Python, R, and SQL locally in your favorite IDE, then scale to Deepnote cloud for real-time collaboration, Deepnote agent, and deployable data apps. Single-player notebooks were great in 2013. 2025 needs reactive, collaborative, AI-ready projects that integrate into your existing stack seamlessly. That's why we're making Deepnote open source - to offer the community an open standard for AI-native data notebooks and data apps. We're standing on the shoulders of Jupyter — it changed how the world explores data. But at team scale, the papercuts stack up: brittle reproducibility, no native data connectors, weak collaboration, and bolted-on AI features. In the enterprise context, this gets very tough to manage - and we're seeing an increasing demand from large companies to move away from Jupyter. What’s new: - Reactive execution (downstream block auto-update) - Powerful blocks beyond code: SQL, interactive inputs, charts, KPIs, buttons - 100+ data integrations - Code in your favorite IDE: Cursor, Windsurf, or VS Code - No lock‑in: open standard; export to `.ipynb` whenever you need Once you're ready to scale in your team, transfer to Deepnote Cloud with one command for beefier compute, powerful data apps from notebooks and agentic data science. Ty it now: Repo ➔ vist.ly/4ctcq Deepnote in VS Code ➔vist.ly/4ctcm Docs -> vist.ly/4ctcf CLI ➔ `npx @deepnote/convert notebook.ipynb` P.S. This only works as an open standard.
