accessr vs Jackett: at a glance
What is accessr?
One R Markdown source, four accessible formats — and a fortnight spent patching around someone else's bug.
accessr turns a single R Markdown file into HTML slides, HTML, Word and PDF output, with an emphasis on producing documents a screen reader can navigate. Accessible PDFs come via OfficeToPDF and are Windows-only, which is the package's main structural constraint. Recent releases have been spent absorbing and then unwinding a fault in the officedown dependency.
What is Jackett?
Jackett's daily release treadmill now spends commits undoing tracker removals it made days earlier.
Jackett ships near-daily auto-generated releases, each carrying a handful of tracker-definition commits: domain bumps, indexers added or removed, request delays, category tweaks. The work is entirely definition maintenance against sites that keep moving — no changes to the application itself appear in this window. Bodies are machine-generated commit lists with no prose.

One R Markdown source, four accessible formats — and a fortnight spent patching around someone else's bug.
◆ Current state
accessr turns a single R Markdown file into HTML slides, HTML, Word and PDF output, with an emphasis on producing documents a screen reader can navigate. Accessible PDFs come via OfficeToPDF and are Windows-only, which is the package's main structural constraint. Recent releases have been spent absorbing and then unwinding a fault in the officedown dependency.
◆ Where it's heading
The package's own development is focused on the details that make output genuinely accessible rather than merely produced — PDF bookmarks generated from Word headings, image dimension handling, header behaviour in slide output. That work is intermittent, and the more visible pattern in 2025 is dependency fragility: a CRAN check failure traced to a strsplit() call inside officedown forced a temporary patch, which was reverted two weeks later once upstream fixed it. Depending on a chain of document-conversion tools means the package inherits their breakages.
◆ Prediction
The next release will likely be another response to an upstream document-tooling change, though the pdf_args work suggests further OfficeToPDF options could be exposed if accessibility gaps surface.
Jackett
5.0INFRA · APIS
Jackett's daily release treadmill now spends commits undoing tracker removals it made days earlier.
◆ Current state
Jackett ships near-daily auto-generated releases, each carrying a handful of tracker-definition commits: domain bumps, indexers added or removed, request delays, category tweaks. The work is entirely definition maintenance against sites that keep moving — no changes to the application itself appear in this window. Bodies are machine-generated commit lists with no prose.
◆ Where it's heading
The notable pattern is reversal. 720pier was removed in v0.24.2404 and restored by revert in v0.24.2414 three days later; scenetime was added as an indexer in v0.24.2398 and dropped four days after in v0.24.2413 when an API class requirement was lifted. Round-trips like these are now a routine part of the cadence, which suggests removals are being made on incomplete information and walked back once users object.
◆ Prediction
The daily cadence continues, dominated by domain bumps and FlareSolverr dependency updates. Expect further add-then-remove round-trips as tracker sites change their access rules faster than definitions can settle.
