Butter.my is a collection of commercial forked modules for enterprise Python projects, branded as “Buttered Python.” It is not affiliated with the Python Foundation. Instead, it offers modified alternatives to Python 2, Pandas, and multiprocessing, aiming to address issues such as large legacy Python 2 codebases, Pandas performance bottlenecks, poor MacOS performance, and the difficulty of scaling single-machine computing workloads to the cloud.
Buttered Python 2 focuses on long-term support for Python 2. It claims 100% compatibility with Python 2 while backporting performance improvements, security fixes, and bug fixes from Python 3, along with proprietary performance optimizations and MacOS-specific optimizations. Buttered Pandas is described as a drop-in replacement for the standard Pandas dataframe library, with an emphasis on better performance and memory usage, and it can scale to the cloud via the Pelts library. Buttered Multiprocessing replaces the standard multiprocessing module and can move computation from Python projects to the cloud. It supports major cloud providers, cloning a .venv into cloud containers, launching multiple workers, and operating via either a headless mode or a web control plane.
The website does not publish pricing, plans, trial options, or licensing terms. It only provides an enterprise contact form, making it a typical custom commercial / sales-led offering. For organizations that need to maintain Python 2 over the long term, commercial support may be valuable, but buyers should confirm the SLA, source-code visibility, delivery scope, cloud resource costs, and security/compliance terms before procurement.
Its main strength is a very focused positioning around three enterprise pain points: legacy Python, Pandas performance, and cloud scaling. It also emphasizes drop-in integration, which could theoretically reduce migration costs. The downsides are also clear: there is very little public information, with no benchmarks, installation documentation, compatibility matrix, customer case studies, or API details. A commercial fork may also introduce vendor lock-in and additional compliance review pressure.
It is best suited to enterprise teams still tied to large Python 2 codebases that cannot migrate to Python 3 in the short term, or teams whose business is significantly affected by Pandas workload performance. It is less suitable for individual developers or teams that prefer the open-source ecosystem. The article provides no information on access from China, so this remains unknown; payment methods are also not disclosed. Potential alternatives include migrating to Python 3, official Pandas, Dask, Ray, Modin, Polars, and cloud-provider-native batch processing or container services.
