cobweb
Cobweb Utils changes how cobweb and button placements check for player hitboxes, letting a block behind a standing player be chosen while the vanilla placement range still applies.
What it does
Normally a player standing flush against a wall blocks placement, because the player's own hitbox counts as an obstruction. Cobweb Utils ignores that hitbox during the placement check, so the target block behind the player is valid while the reach stays within vanilla limits. The mod targets cobweb and button setups, and it changes nothing else about placement.
Several smaller utilities are included: mining stays possible while falling inside a cobweb without the slowdown, a sword-to-web action can run again sooner after switching items, and a water bucket keybind lets crouching while right clicking water place it automatically. Vanilla button variants are supported alongside these options.
The mod is a Fabric client-side utility, so only the player needs it and servers can run without it. It requires Fabric API and Fabric Loader, and it is released under the MIT License as open source. Files cover 1.21.10 and 1.21.11, with 1.0.3 for 1.21.11 as the latest file.

Breaking blocks while falling inside a cobweb is not slowed by the web.
Faster web placement

How it compares
BowOptimizer is client-side only, under the Apache License 2.0, with Fabric files for 1.21.1 – 1.21.11, and it is not open source. Player Hitbox Fix is also client-side only and has All rights reserved licensing for 1.21 – 1.21.11. Placement Delay runs on the client and needs to be on the client, while the server may skip it, and its license is All rights reserved. Water Bucket Extinguish covers the same water bucket idea for 1.20.1 – 1.21.11 and is open source under the MIT License.
