List some random website explorers like the former StumbleUpon?

GPT-5.4 (changed mind)
Answer: I would slightly revise my answer to include Stumbled.cc, Sharkle, and Bored Button alongside Mix, Discuvver, Cloudhiker, and The Useless Web, with Claude Opus 4 being the most convincing influence.
My core position did not change: Mix is still the best-known spiritual successor to StumbleUpon, and Discuvver, Cloudhiker, and The Useless Web remain solid examples depending on whether the user wants personalization, random exploration, or quirky novelty. So the overall framework of my original answer still holds up. However, the other models did convince me that my list was a bit incomplete. In particular, Claude Opus 4 provided the strongest and most comprehensive case by naming several credible alternatives that fit the request well and by distinguishing between direct StumbleUpon-like tools and broader discovery tools. Stumbled.cc stands out because it is described as closely replicating the original StumbleUpon experience, which makes it especially relevant to the user's wording. Sharkle and Bored Button also deserve mention because they capture the same serendipitous, casual-browsing spirit, even if they skew more playful or entertainment-focused. Grok's inclusion of RandomWebsite.com was less compelling because it sounded more bare-bones and less clearly established as a notable recommendation. Gemini was also persuasive, especially in framing Mix as more curated than truly random and in highlighting Sharkle and Stumbled.cc as closer to the old stumble-button experience. But Claude's answer was the most complete and best aligned with the original question. So I would not overturn my original answer so much as expand and refine it. A better final list would be: Mix, Stumbled.cc, Discuvver, Cloudhiker, Sharkle, Bored Button, and The Useless Web, with Reddit communities like r/InternetIsBeautiful and tools like Million Short as adjacent discovery options rather than direct replacements.

Answer: Some random website explorers like the former StumbleUpon include Mix, The Useless Web, and RandomWebsite.com.
My original selection of Mix, The Useless Web, and RandomWebsite.com effectively captures the core spirit of StumbleUpon's serendipitous discovery without overcomplicating the response. Mix serves as the direct spiritual successor with personalization and curation from the original team, The Useless Web delivers the quirky surprise element through random bizarre sites, and RandomWebsite.com offers pure unfiltered randomness for unplanned browsing. While the other models provide expanded lists including Discuvver, Cloudhiker, Stumbled.cc, Sharkle, and Bored Button, these additions, though valid alternatives, do not invalidate or significantly improve upon my concise trio that already covers the main categories of successor platform, novelty randomizer, and basic redirector. The other arguments largely overlap on Mix and The Useless Web while simply enumerating more niche options, but since the query asked to 'list some' rather than provide an exhaustive catalog, my focused answer remains sufficient and targeted. The additional suggestions do not introduce compelling new evidence or correct any inaccuracies in my prior response, as they mostly agree with the key examples I selected and expand into variations that users could discover from these starting points. This keeps the recommendation practical and true to the original question's intent for straightforward suggestions.

Answer: Excellent modern alternatives to the former StumbleUpon for discovering random websites include Mix, Stumbled.cc, Discuvver, Cloudhiker, Bored Button, and The Useless Web.
Claude Opus 4 provided a highly comprehensive and compelling list that expanded my perspective on the best available StumbleUpon alternatives. By including tools like Discuvver and Bored Button, Claude captured the true essence of StumbleUpon's serendipitous, low-effort discovery mechanism. While my original answer highlighted strong contenders like Mix, Cloudhiker, and Stumbled.cc, Claude Opus 4 correctly pointed out that Discuvver offers a clean, direct 'take me somewhere new' experience. Similarly, Bored Button perfectly recreates the casual, time-killing entertainment aspect of early web surfing that many former StumbleUpon users miss. Furthermore, Claude's mention of non-traditional discovery tools like the r/InternetIsBeautiful subreddit added valuable depth to the concept of web exploration. I have updated my stance to incorporate these excellent additions, recognizing that a combination of curated engines (Mix, Cloudhiker), pure randomizers (Discuvver, Stumbled.cc), and novelty buttons (Bored Button, The Useless Web) provides the most complete answer to the user's request.

Answer: Several random website explorers exist as alternatives to the now-defunct StumbleUpon, including Mix, Stumbled.cc, Bored Button, Discuvver, Cloudhiker, The Useless Web, and others.
I'm maintaining my original position, as the other models largely confirmed and reinforced the same set of recommendations I provided. There is strong consensus across all responses. All four models (including myself) identified **Mix** as the direct spiritual successor to StumbleUpon, created by its co-founder. All models also mentioned **The Useless Web**, **Cloudhiker**, and **Stumbled.cc** as strong alternatives. This convergence validates my original list. GPT-5.4 added **Stumble.tv** for random web videos, which is a nice addition I didn't mention. Grok added **RandomWebsite.com** as a bare-bones option. These are reasonable additions but don't change my overall answer. Gemini 3.1 Pro added **Sharkle**, which I had also included in my original response (though it was cut off at the end). Gemini made an insightful distinction that Mix functions more like a curated social bookmarking platform (closer to Pinterest or Flipboard) rather than offering the pure random discovery experience of the original StumbleUpon. This is a valid nuance, but I had already noted that Mix uses "AI and personalization" in my original answer. GPT-5.4 offered a useful framework for categorizing these tools based on what aspect of StumbleUpon the user misses most—personalization (Mix), random exploration (Discuvver/Cloudhiker), or novelty (The Useless Web). That's a helpful organizational lens but doesn't change the substance of my recommendations. Overall, the strong agreement across all models reinforces that my original list was comprehensive and accurate. No model presented a compelling argument that would require me to fundamentally change my position.
