As a Homestuck page, all spoilers related to the main comic will be unmarked. For those who have not read up to the Gigapause, this is your only warning. The Paradox Space spoilers will be unmarked too, since it's freely available and there's no barrier to reading it.
''Those who like [Homestuck] are extremely fond of the characters, yet those characters are trapped — "stuck" if you will — inside a very particular narrative, which itself has been at the mercy of my ability to produce it. So when I think about the future of Homestuck, I envision projects which liberate the things people love about it from the story itself, and most importantly, from my intensive personal effort. So this website is the first major step in that direction.
Paradox Space is a Spin-Off of Homestuck, updated every weekday. A webcomic anthology, it was launched on 4/13/2014, Homestuck's fifth anniversary, as a surprise for the Homestuck fandom, and motivated by the desires of Andrew Hussie to ensure that the world of Homestuck wouldn't be completely limited to what he had the time and energy to create. It can be found here.Paradox Space itself is comprised of short stories with no overarching narrative, by various artists and writers working in tandem. Some of them are "possibly canon" to the main story of Homestuck, depicting takes on off-screen events alluded to in-comic or new tales plausibly set somewhere in the original comic's timeline, while others are decidedly non-canon and set in "doomed timelines", alternate scenarios, or simple silly situations featuring Homestuck characters.

This webcomic provides examples of the following tropes:
Adorkable: Vriska and Eridan, of all people, are this in "Critical Miss", where they can be seen playing FLARPing and at the beginning, they're hunched over rule books and character manuals. Eridan especially, with his hilariously bad attempts at flirting and accusing Vriska of cheating.
Alt Text: Some of the comics have this. Not all of them have it, but some may be added at any time. The only way to know when new alt text is added is to regularly check every comic.
Always Murder: Berrybreath remarks in Indemnity Double Reacharound that it's "always murder in this load gaper of a town."
Broad Strokes: Hussie has stated that there are two types of stories in this webcomic — those that are not canon (be they doomed timelines or Alternate Universes), and those that are possibly canon, which would count as this trope. The only stories that are confirmed to be canon are ones that Homestuck proper actually alludes to in some way.
The Alt Text for the last page of A Fun Day for Bec is "GOOD DOG. BEST FRIEND." That's a reference to an early part with Jade in Homestuck.
The Alt Text for the first page of Soul-Flaying Games is "what's a mom?", calling back to Suffering for/through the People when a troll asked the Sufferer the same question.
Cassandra Truth: In John's Birthday, John tells Dave that the zoo's monkeys have knives. Dave takes this for an attempt at comedy, and berates John for his lack of originality. Of course, John is telling the truth.
Cheaters Never Prosper: If the Alt Text in Con Faire is fully part of the comic, then part of the reason it ended in a Crack Defeat was because Vriska attempted to mind control WV into judging her the winner, and he found out.
Cloud Cuckoolander: "Quality Time" highlights just how weird Bro was sometimes. Apparently to teach Dave life lessons, he has Dave sit inside a concrete ball pit at a store he frequents. Except that said ball pit is empty, so it's just Dave sitting in a concrete hole in the ground until Bro gets done shopping. He also apparently buys hand-to-hand weapons from the same place he buys his groceries.
Curse Cut Short: In Critical Miss, Eridan manages to say "Oh shi-" before Vriska goes medieval on him.
Darker and Edgier: Becquerel's 'fun day' is a global game of fetch. GCat's is a global safari, in which he hunts whatever animal he can get his shiny paws on.
Deadly Game: Eridan and Vriska's game in Critical Miss is one; if Vriska wins, she gets to feed Eridan's lowblood 'slaves' to her lusus.
Defeat Equals Explosion: In Hunting Lesson, an imp Equius punches explodes into a grist-raining fireball as it flies into the horizon, though that is a standard reaction of Denizen constructs in the comic proper.
Flat "What.": Very, very prevalent throughout Horse Play in regards to Doc Scratch's reactions to Hussie's chess shenanigans.
For Want of a Nail: Prototyped deviates from canon events merely from John picking up an extra harlequin figurine. Indeed, the last page has John and Dave lampshade the fact that they're in a doomed timeline.
Mood Dissonance: In Homestuck tradition. For example, Stardom depicts a crazed serial killer playing with the corpses of his victims, and is rendered in bright, cartoony art.
Mood Whiplash: The strips' unconnected nature makes this inevitable, although most of them seem to be either comedy-based on light in nature. Quality Time goes from a humorous exchange between John and Dave over bro shops to Dave monologuing about being left alone in an empty concrete ball pit for hours in the span of two pages.
Mook Lieutenant: The Lich in "Party Crashers" is the most prominently featured of the Underlings and seems to be the "spokesperson" of the group.
Multiple Choice Past: Equius lost his horn during a struggle with out-of-control robots. Or after being mauled by the sweati. Depends on the timeline.
One-Hit Kill: In Hunting Lessons, both Equius and Nepeta kills their prey in one strike.
Only Sane Man: Judging by Suffering Through/For The People, the Sufferer was this for pretty much the entirety of the troll race. Even his followers like the Psiioniic and Disciple don't seem very bright.
Parental Neglect: Bro apparently likes to take Dave to weekend trips to a gimmicky dollar shop, which consists mainly of Bro leaving Dave all alone in an empty concrete pit for hours at a time while he windowshops.
With Catlike Tread: Done appropriatelyenough with Nepeta in Hunting Lesson. She tells Equius that she will teach him about sneaking up on prey and then immediately leaps over their cover and flying-kicks an underling in the face.
