Plotly vs writexl

Plotly vs writexl: at a glance
What is Plotly?
Plotly is turning its cloud into a metered compute platform with an enterprise on-ramp.
Plotly ships on two tracks. Plotly Studio, the desktop AI app-builder, releases every one to two weeks and has spent v0.0.80 through v0.0.86 on credential handling, reasoning transparency, personalization and now the reliability of the agent session engine itself. Plotly Cloud is the louder track: since late May it has added viewer-seat pricing, domain verification, per-app compute modes with credit-metered billing, and customer-owned domains with managed TLS.
What is writexl?
writexl spent nine years refusing to do formatting, then shipped all of it in 2.0.0.
For most of its history writexl was a deliberately minimal wrapper: bump the vendored libxlsxwriter, handle NA and Date coercion correctly, support a list of data frames for multiple sheets, and nothing else. 2.0.0, released August 2026, changes that — near-full libxlsxwriter coverage, cell/worksheet/workbook formatting, cell comments, an `xl_cell_general` class carrying value, formula and hyperlink, a cell-by-cell refactor, libxlsxwriter 1.2.4, and memory-safety work. It landed the same day as 1.5.4, a typo fix on the old line.

Plotly is turning its cloud into a metered compute platform with an enterprise on-ramp.
◆ Current state
Plotly ships on two tracks. Plotly Studio, the desktop AI app-builder, releases every one to two weeks and has spent v0.0.80 through v0.0.86 on credential handling, reasoning transparency, personalization and now the reliability of the agent session engine itself. Plotly Cloud is the louder track: since late May it has added viewer-seat pricing, domain verification, per-app compute modes with credit-metered billing, and customer-owned domains with managed TLS.
◆ Where it's heading
The Cloud releases are assembling the standard pieces of a hosting business in order — identity first (domain verification, explicitly framed as the step before SSO), then billing (viewer seats, then metered compute credits), and now production-grade serving (custom domains, automatic certificate renewal). Studio is being hardened as the authoring front end that feeds it: Universal Deployment pushed beyond Dash apps, credentials saved once and reused, a Winget channel to widen Windows installs, and in v0.0.86 a rebuilt session engine plus automatic retries so agent runs survive expired tokens. The two tracks converge on one funnel — author in Studio, deploy to Cloud, pay by compute consumed.
◆ Prediction
The Domain Verification entry names SSO as the next step and places it in the Enterprise tier, so single sign-on is the most likely Cloud release next. Studio should hold its one-to-two-week cadence, with the newly added app thumbnails pointing toward more work on browsing and organizing generated apps.

6.3ANALYTICS
writexl spent nine years refusing to do formatting, then shipped all of it in 2.0.0.
◆ Current state
For most of its history writexl was a deliberately minimal wrapper: bump the vendored libxlsxwriter, handle NA and Date coercion correctly, support a list of data frames for multiple sheets, and nothing else. 2.0.0, released August 2026, changes that — near-full libxlsxwriter coverage, cell/worksheet/workbook formatting, cell comments, an `xl_cell_general` class carrying value, formula and hyperlink, a cell-by-cell refactor, libxlsxwriter 1.2.4, and memory-safety work. It landed the same day as 1.5.4, a typo fix on the old line.
◆ Where it's heading
The package has changed category. Its selling point was being the dependency-free, opinion-free way to get a data frame into xlsx; 2.0.0 makes it a formatting-capable writer that now compares itself against openxlsx2 in its own test suite. The cell-by-cell refactor is what made that possible and is also the largest structural change in the package's history. Note that a single contributor drove essentially all of it.
◆ Prediction
Expect follow-up releases fixing edge cases in the new formatting and comment APIs — the cell-by-cell rewrite is too large to land clean, and the 2.0.0 notes already mention an off-by-one in date columns.
