18 entry descriptions overstated, understated, or misattributed their projects, checked against upstream on 2026-09-27 and approved row by row.
- django: "most popular" contradicted by the 2024 JetBrains/PSF survey, where FastAPI leads overall; now uses Django's own tagline.
- joblib: described as pipelining; its docs say parallel computing and disk caching.
- huey: called only "multi-threaded"; it also supports multi-process and greenlet workers.
- numba: updated to its current NumPy-aware wording.
- pytesseract: credited Google as Tesseract's developer, which ended in 2017.
- pennylane: description was narrower than its quantum computing/QML/chemistry scope.
- channels: didn't mention WebSocket support.
- justhtml: left out that it sanitizes untrusted HTML by default.
- akshare: left out its academic-research-only data terms.
- timesfm: left out its non-commercial default weights.
- pyvips: used libvips's own tagline instead of describing it as a binding.
- ultralytics: dropped an unverifiable SOTA claim and added its tracking capability.
- pandera: listed only 3 of its supported dataframe backends.
- sentry-skills: claimed a Python focus and debugging scope; it's the Sentry team's own skill set.
- trailofbits-skills: claimed to be Python-friendly, but only 2 of 85 skills are Python-specific.
- mysqlclient: fork link pointed to SourceForge mysql-python instead of MySQLdb1, and it now notes MariaDB support.
- charset-normalizer: called "the default" of requests, which prefers chardet when installed.
- pynacl: described as binding NaCl directly; it binds libsodium, a NaCl fork.

Computer Vision's description said nothing; Template Engines claimed lexing; Email claimed parsing and mail server management though yagmail only sends; Build Tools said "compile software" though Invoke and doit are task runners; File Format Processing said "text formats" though it covers ELF, xlsx, docx, and PDF; Package Repositories left out mirrors like bandersnatch. These descriptions show on the category pages.

Keep the docs link inline in the description instead of as the primary entry link, matching the format used by other entries.

django.db.models, geodjango, httpx.URL and uv audit were rendering
"Not on PyPI" alongside eighteen genuinely standalone projects that
simply are not packaged on PyPI, conflating two different reasons for
a missing download count.
These four entries now carry a "(part of X)" description prefix in
README.md, mirroring the existing "(Python standard library)"
convention. build.py reads that prefix into a bundled flag that both
templates render as a "Bundled" badge.
The prefix approach was chosen over a separate data file so README.md
stays the single source of content truth, and over inferring from the
entry name because geodjango is neither dotted nor spaced and would
have been missed. Redundant tail wording was trimmed from the
httpx.URL, geodjango and uv audit descriptions now that the prefix
names the parent.
The new entry format is documented in CONTRIBUTING.md and the
vocabulary in CONTEXT.md.

Material for MkDocs went into maintenance mode on 2025-11-05 and its
own team called upstream mkdocs unmaintained since 2024-08 and a
supply chain risk; the mkdocs repo was last pushed 2025-10-20. Since
mkdocs-material hard-depends on mkdocs, mkdocs' download count is
almost entirely mkdocs-material pulling it in (18,360,677/month vs
mkdocs-material's 18,167,775/month, ~1% delta), so dropping the
redundant direct entry costs little. zensical is a clean replacement
with no mkdocs dependency, built by the same Material for MkDocs
team, at 1,585,786 downloads/month and 5,540 stars, pushed
2026-08-21. Added as a challenger, placed last below pdoc, keeping
the section at 5 of 5. Approved via verdict preview.

Obvious choice for physical units and dimensional analysis in Python: 8,647,557 downloads/month (pepy.tech, 2026-08-23), more than twice astropy (3,713,879) and thirty-six times obspy (237,352), 2,781 stars, created 2012, pushed 2026-08-05. PyPI classifier still reads Beta at v0.25.3, treated as stale given fourteen years of history and download scale (judgment call). Listed under Physics and Engineering per maintainer choice over minting a Units and Quantities subcategory.

Audit of proposed additions from a YouTube video roundup. Admitted as
a challenger: 761,507 downloads/month (pepy.tech, 2026-08-23) already
outranks the incumbent prospector (497,880), the repo is active
(pushed 2026-08-21, version 7.0.1, Production/Stable) and it has
reached 794 stars since being created in January 2024. It fills a
real gap: ruff's PLR0912 measures cyclomatic complexity while
complexipy measures cognitive complexity, and the two are
complementary. Adoption-trajectory evidence is thin, so the
challenger tier is a judgment call. Placed last in the subcategory
since position marks tier and challengers follow obvious choices.

Audit of proposed additions from a YouTube video roundup. transitions
has not been pushed since 2025-09-11 and crosses the 12-month activity
line on 2026-09-11, while python-statemachine is actively developed
(pushed 2026-08-17, version 3.2.1 released 2026-08-01) and covers
strictly more (SCXML-compliant statecharts, compound and parallel
states, history, sync and async). Downloads 1,422,332/month vs
transitions 3,137,416/month (pepy.tech, 2026-08-23).

Pydantic Services took over stewardship of the stalling httpx under the httpx2 name, Starlette already switched its TestClient, and it hit 144M downloads/month (pepy) within 3 months of first release at Production/Stable v2.12.0. Placed last in the challenger tier behind urllib3 per the downloads-descending ordering rule. Fork format and a rewritten description distinguish it from httpx, whose PyPI summary is identical.

Add seleniumbase to Testing — Browser Automation as a challenger (2.86M downloads/month via pepy vs selenium 56.9M; admitted by maintainer decision). Entry placed per Entry Ordering, display name set to the canonical PyPI package name.
The entry linked hydra-ecosystem/hydra, an unrelated W3C Hydra API
toolkit, while the entry name and description describe
facebookresearch's Hydra configuration framework, mixing the wrong
repo's stars with the right package's identity. Found during the
downloads-column identity sweep.

Re-homed pyenv-win from a pyenv sub-item (Environment Management) to a full entry in Microsoft Windows, placed before winpython by downloads (25.8k/mo vs 172). Actively maintained, pushed 2026-08-14, 7,360 stars. Maintainer preference is to move sub-items to a fitting category rather than delete.

Flower isn't a task queue, so nesting it under celery misclassified it; Task Queues is also at its entry cap. Monitoring and Processes is its honest home, ranking fourth by downloads (12.35M/mo ClickPy, between supervisor 17.0M and sh 11.8M), and Celery's own docs name it the recommended monitor. Repo pushed 2026-08-16 with 7,232 stars. This fills Monitoring and Processes to its 5-entry cap.

Was a sub-item under mkdocs. By downloads it ranks second in the
section at 17.6M/mo (ClickPy), above mkdocs' 17.4M, and it powers
FastAPI, Pydantic, and Ruff/Polars docs (27,269 stars, pushed
2026-08-09). Documentation now sits at its 5-entry cap.

Not a tool readers install: type checkers bundle it automatically as a

Sub-item policy reserves sub-items for awesome-* links. aws-sdk-pandas

Maintainer reversal of c0a31ce, restoring the entry and its
awesome-fasthtml sub-item to their prior position. The
challenger-limit override that rode the move is withdrawn with it —
Asynchronous returns to 4 entries within the standard cap shape.

Re-admission on maintainer word, reversing the Data Analysis sweep's
drop (f3c920d — the xlsxwriter reversal precedent): the drop was
partly a mis-homing casualty, since its honest home, an ETL use case,
did not exist then. The repo self-describes as a Python ETL framework
for stream processing and LLM/RAG pipelines: 62.5K stars, pushed
daily; 16.5K downloads/month is weak for the star count and noted.
Enters as challenger behind dlt (7.8M/mo).

The safishamsi/graphify URL is a stale redirect — the repo moved to
Graphify-Labs/graphify (verified via the GitHub API). Maintainer
declined the Agent Skills re-home; the entry stays in Data
Visualization > Specialized with its link fixed.

Maintainer-adjudicated close of the standing flag: fasthtml runs on
Starlette and Uvicorn (ASGI), so Synchronous was the wrong shelf. It
lands as a third challenger behind starlette and tornado's obvious
choices — the use case holds 5 with 3 challengers by explicit
maintainer override (Async I/O precedent; the awesome-fasthtml
sub-item rides along). 1.19M downloads/month as python-fasthtml.

No removals. mimetypes and pathlib (standard library) lead
alphabetically under the stdlib-first rule; watchfiles (389.3M/mo,
partly uvicorn-transitive — the riser) completes the obvious choices;
watchdog (113.3M/mo, the demoted incumbent, Second Tier) and
python-magic (32.3M/mo) challengers.
Co-Authored-By: Claude <noreply@anthropic.com>
Tiers: beautifulsoup4 (renamed from beautifulsoup — the bare PyPI
name is the abandoned bs3 shim; 451.4M/mo, docs link per the PyQt
precedent), lxml (401.3M/mo), xmltodict (124.5M/mo) obvious choices;
markupsafe (820.5M/mo — the section's biggest raw count, but
jinja-transitive infrastructure, so challenger on judgment; watch:
quiet since 2025-09) and justhtml (67.8K/mo, 1.1K stars in two
years — trajectory judgment on a young pure-Python HTML5 parser)
challengers.
Removed:
- html-to-markdown — coordinated multi-entry self-promotion
(automatic-rejection rule): PyPI provenance verified to xberg-io,
the org's fourth planted entry overall. 1.5M downloads/month is
real but the rule stands.
- pyquery — 2.2M downloads/month and an active repo (pushed
2026-07); editorial drop at cap: the jQuery-style API is the
least-reached-for of the keeps. Judgment call.
- tinycss2 — 110.5M downloads/month is transitive (weasyprint
declares it a hard dependency, verified in PyPI metadata) against
190 stars; a CSS parser mis-homed in an HTML/XML section with no
better home. Judgment call.

The industry's fuzzy string matching answer (web-verified: the
production recommendation over thefuzz — same API, MIT license, C++
speed — and preferred over textdistance for string metrics). 181.7M
downloads/month (pepy), 4.1K stars, pushed 2026-08. Sole obvious
choice; the subcategory label rides this commit so it is never empty,
completing the displacement of textdistance.

The ecosystem's default encoding detector — requests switched to it
in 2021 and 2026 guidance names it the choice for new projects
(web-verified). 1.73B downloads/month (pepy; heavily
requests-transitive, but default-status is the point), pushed
2026-08. Co-obvious with chardet, which retains a verified accuracy
claim — the PyQt/PySide pair shape.
Co-Authored-By: Claude <noreply@anthropic.com>
Restructure: the 10-entry General grab-bag dissolves — Encoding and
Unicode (chardet 224.1M/mo obvious choice, joined by
charset-normalizer next commit; ftfy 14.4M/mo kept as the fifth
mature-stable past-line keep, repo and release both 2024-10),
Internationalization (babel 135.2M/mo sole), Transliteration and
Slugs (python-slugify 87.7M/mo, unidecode 31.8M/mo), and a residual
General (difflib stdlib-first, pyfiglet 6.2M/mo judgment keep).
pypinyin (1.9M/mo) and pangu.py (14.9K/mo as PyPI pangu — display
name kept by explicit maintainer word, the second deliberate naming
exception after pytorch; kept on sole-tool judgment for CJK spacing)
re-home to Natural Language Processing > Chinese as challengers
beside jieba. Parser re-tiers: pygments (1.25B/mo), pyparsing
(422.3M/mo), sqlparse (146.8M/mo) obvious choices; phonenumbers
(renamed from python-phonenumbers, 39.4M/mo) and parsy (4M/mo)
challengers. Unique identifiers reorders to shortuuid then sqids.
Removed:
- textdistance — last release 2024-07 (25 months) and repo quiet
since 2025-04, past the 12-month line; displaced by rapidfuzz
(181.7M/mo vs 2.5M), entering in its own commit.
- python-nameparser — 3.3M downloads/month (as nameparser) and an
active repo; editorial drop at cap: the domain-parser class is
trimmed to the giant, phonenumbers. Judgment call.
- python-user-agents — repo quiet since 2023-02, three and a half
years past the 12-month line.
- tree-sitter-language-pack — coordinated multi-entry self-promotion
(automatic-rejection rule): PyPI provenance verified to xberg-io,
the org that previously planted xberg and liter-llm. 6.6M/mo is
real but the rule stands; its sibling drops from HTML Manipulation.
Co-Authored-By: Claude <noreply@anthropic.com>
No removals. General tiers: opencv-python (renamed from opencv to the
canonical pip package this entry already linked; 55.9M/mo) and
ultralytics (8.4M/mo, 60.7K stars) obvious choices; kornia (3.1M/mo)
and fiftyone (253.7K/mo — dataset tooling rather than a vision
algorithm library, kept as the unprompted answer for that adjacent
job) challengers. OCR minted as a distinct job: pytesseract (24M/mo)
and easyocr (3.6M/mo, quiet since 2025-12 — watch) obvious choices.
Co-Authored-By: Claude <noreply@anthropic.com>
General tiers: nltk (71.4M/mo), spacy (25.4M/mo) obvious choices;
gensim (6M/mo, quiet since 2025-11 — watch) and stanza (1.1M/mo)
challengers. Chinese: jieba kept as mature-stable past the 12-month
activity line (repo quiet since 2024-08, last release 0.42.1 in
2020-01) on the sortedcontainers precedent — the fourth such keep:
3.3M downloads/month, 35.1K stars, still the Chinese segmentation
answer with no successor.
Removed:
- funnlp — three independent grounds: a link-collection rather than a
library; repo quiet since 2024-05, past the 12-month line; 55
downloads/month. Its 82.5K stars measure the bookmark, not a tool.
Co-Authored-By: Claude <noreply@anthropic.com>
Restructure: the 12-entry flat section splits into General
(scikit-learn 234.7M/mo obvious choice; pgmpy 843.7K/mo and
feature-engine — renamed from feature_engine to its canonical PyPI
name, 297.1K/mo — challengers), Gradient Boosting (xgboost 52M/mo,
lightgbm 26.5M/mo, catboost 6.3M/mo, all obvious choices; lightgbm's
lightgbm-org link verified current — microsoft/LightGBM redirects
there), and Time Series Forecasting (timesfm sole — a foundation
model judged by ecosystem adoption, 285K/mo and 27.6K stars; prophet
and darts are named absences, deliberately not added this sitting).
Removed:
- h2o — 215.1K downloads/month, 7.5K stars, and the repo is active;
the drop is purely editorial: no longer anyone's unprompted answer
against scikit-learn and the boosting trio. Judgment call.
- mindsdb — the linked repo redirects to mindsdb/mindshub, a "models
workspace"; the AI-layer-for-databases product this entry described
no longer exists (verified). 23.9K downloads/month.
- scikit-lego — 72.5K downloads/month, 1.4K stars; a grab-bag of
sklearn extras that never became an unprompted answer. Judgment.
- TabGAN — 574 stars, 2.3K downloads/month. Nowhere near the bar.
- spark.ml — duplicate in all but name: pyspark is already listed in
the audited DevOps group, same repo, same pip install. Structural.

The RL environments standard: community successor to OpenAI Gym
(unmaintained since 2022; few maintained RL libraries still support
old Gym — web-verified). 6.5M downloads/month (pepy), 12.3K stars,
pushed 2026-08. Obvious choice beside stable-baselines3, ordering
first by downloads.
Co-Authored-By: Claude <noreply@anthropic.com>
No removals. Frameworks tiers: pytorch (96.6M/mo as PyPI torch — the
display name stays pytorch by explicit maintainer word, a deliberate
exception to the naming convention; the bare pytorch PyPI package is
a squatting placeholder), tensorflow (19.2M/mo — production incumbent,
flagged as a Second Tier demotion candidate for the next audit), keras
(18.6M/mo, backend-agnostic since Keras 3) obvious choices; jax
(21.8M/mo, TPU/performance trajectory) and pytorch-lightning
(11M/mo) challengers. Landscape verified: PyTorch is the 2026 default
with 85% research share.
stable-baselines3 moves into the minted Reinforcement Learning
subcategory — RL is a distinct job; gymnasium joins it next commit.

Maintainer challenge upheld: Odoo is a ready-made web application
platform you extend, the sibling concept of CMS and Admin Panels —
so the section belongs beside them, not in the Other grab-bag (its
first placement was inertia from tryton's Miscellaneous home). TOC
and body both move; the group's section tail stays alphabetical
(Admin Panels, CMS, ERP, Static Site Generators).
Co-Authored-By: Claude <noreply@anthropic.com>
The Python ERP by adoption: about 7M users across editions, 50+ app
modules, 53.7K stars, pushed daily (web-verified). Not pip-distributed
— the PyPI odoo package is a dateless placeholder — so no download
signal; judged by ecosystem and displayed by repository name (renpy
precedent). Sole obvious choice.
Second structure override of decision 18 by maintainer word (Supply
Chain Security precedent): ERP lands as a new section in the Other
group rather than a slot in the Miscellaneous grab-bag, replacing the
dropped tryton. TOC line, heading, and description ride this commit.
