The short version

  • Each has a real cost: Python the global interpreter lock serialises bytecode execution within a process, so CPU-bound parallel work needs multiprocessing with its memory duplication and serialisation costs; the free-threaded build added in 3.13 is opt-in and much of the compiled ecosystem does not yet support it.; Rowy every Firestore limit is inherited, including the one megabyte per document ceiling and roughly one sustained write per second per document, which surprises users who expect spreadsheet behaviour.
  • They diverge on capability: Python covers C extension interface, Rowy covers Firestore backed grid.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Python

  • The global interpreter lock serialises bytecode execution within a process, so CPU-bound parallel work needs multiprocessing with its memory duplication and serialisation costs; the free-threaded build added in 3.13 is opt-in and much of the compiled ecosystem does not yet support it.
  • Dependency resolution is the standing cost of the ecosystem: a project pinning a CUDA-linked framework, a NumPy major version and a dozen libraries that constrain both produces multi-gigabyte images and installs that break whenever one of those publishes a new major version.
  • Ecosystem-wide binary breaks propagate badly, because a library compiled against an older extension interface fails at import with a low-level error rather than a clear message, and a team with a frozen environment discovers it cannot add one package without rebuilding all of them.
  • Dynamic typing pushes whole categories of error to run time, which in machine learning means a shape mismatch or a None surfacing six hours into a training job rather than at a compile step, and type hints are optional, unenforced at run time and applied inconsistently across ML libraries.
  • Interpreter start-up and per-call overhead make it a poor host for low-latency serving of small models, where the wrapper can cost more time than the inference itself, which is why serving layers get rewritten in Go, Rust or C++ once traffic justifies the work.

Rowy

  • Every Firestore limit is inherited, including the one megabyte per document ceiling and roughly one sustained write per second per document, which surprises users who expect spreadsheet behaviour.
  • Firestore has no joins, so linking tables in the grid is a convenience layer rather than a relational feature and reports across collections still need a separate query.
  • It is useful only to teams already on Firebase, so choosing it effectively locks the operational tooling to one cloud vendor.
  • Query costs are billed by document read, and an unfiltered grid on a large collection can generate a bill that a spreadsheet user has no intuition for.
  • Development activity has slowed relative to the broader category, so evaluate current maintenance before making it load bearing for internal operations.

Answered from the vendors’ own pages

Python: Which version should I use for machine learning?

Usually one release behind the newest. Compiled ML wheels lag the interpreter by months, and being first to a new version mostly buys you a broken environment.

Rowy: Where is my data stored?

In your own Firestore instance inside your own Google Cloud project. Rowy does not hold a copy.

Python: Is Python too slow for machine learning?

The numerical work is not in Python. It matters for data preprocessing loops written in pure Python and for serving small models at high request rates, and in both cases the answer is to move that specific part into a vectorised library or a compiled extension.

Rowy: What does it cost to run?

No licence fee. You pay Google Cloud for Firestore reads, writes, storage and function invocations, and an open grid on a big collection reads a lot.

Python: pip or conda?

pip with virtual environments, or uv, is simpler and now covers most cases. Conda still earns its place when you need non-Python system libraries, particular CUDA builds or a scientific stack pinned as a set.

Rowy: Can it do joins across collections?

Not really. Firestore does not support joins, and no interface layer can add them.

Python: Do I need to know C to work in machine learning?

No, but you need to know that the libraries are C underneath, because that explains why an error message is unreadable, why a wheel will not install and why one line of pandas is a thousand times faster than the loop it replaced.

Rowy: Is there a row limit?

Not from Rowy. The limits that bite are Firestore document size and per document write throughput.

Python: Is the global interpreter lock being removed?

A free-threaded build exists from 3.13 onward as an opt-in variant. It is not the default, and the compiled libraries that matter for machine learning are still working through support for it.

Rowy: Is it suitable if I am not on Firebase?

No. It is specifically a Firestore interface.
