SANSA, Korea's Online Temple Where You Can't Talk, Hit 100,000 Visitors a Day in Two Days

SANSA, an online temple built by a Korean solo developer who goes by “Metamong,” has no chat feature. It was left out on purpose. And because of that very blank, within two days of opening, 100,000 people a day were walking into this temple.

You can share a bench, but you can’t start a conversation

SANSA is a website that needs no install. Log in and a 3D temple hall surrounded by mountains and trees opens, and you become a little child-monk character. Names are assigned automatically, things like “Unhurried Cloud,” “Soft Moonlight” and “Kind Moss” (Money Today, Sidae Ilbo, October 30, 2026). There are only three buttons at the bottom of the screen: palms together, bow, and prayer beads. Tap “listen to chanting” at the top and you hear a wooden moktak and the Heart Sutra, while the count of beads you’ve rolled piles up in the corner (Nongmin Shinmun, October 30).

Sansa means “mountain temple” in Korean, and seven of Korea’s mountain monasteries were added to UNESCO’s World Heritage list in 2018 (Ministry of Foreign Affairs). The developer carried that old name into the smartphone and attached a single rule: “You can sit together, but you can’t talk to each other” (developer’s introduction, cited by Money Today). Its own tagline: “an online temple where we sit together without words” (Nongmin Shinmun).

Erase conversation, and one gesture is left: palms together

There’s only one thing you can do to another person. When the person next to you presses their palms together, a notice pops up on your screen: “They greeted you with palms together” (Nongmin Shinmun). When one person does it, you can see the child monks around them follow (Sidae Ilbo). No talking, no username search, no friend requests.

In an era when nearly every social app is designed to make you “connect more,” SANSA was built by taking connection away. And that’s exactly what users praise. “I’m a capital-I introvert, and here I can sit in the front row” (cited by Money Today). “I stopped by on my way to work to settle my mind. It’s my first time ever at a temple.” “I’m not religious, but it seems to calm me, so it feels good” (same article). More people came looking for a room where they don’t have to answer anyone than came looking for a religious app.

The starting point the developer described wasn’t a feature but energy. “There are days when going to a temple feels like it would help, but actually going takes effort.” “You can bow once, roll a few beads and leave. For those of you without the energy to go all the way to a temple, sit here a moment before you go” (cited by Money Today, Asia Economy).

A hall that opened with 20 seats had 10,000 three days later

SANSA opened on October 28 (HuffPost Korea). At first, the hall held 20 people. On the 29th, the developer posted on Threads that about 12,000 people had rushed in on the first day and crashed the server, and wrote again that night that daily visitors had hit 100,000 (Nongmin Shinmun). The two posts drew about 7,100 and 4,500 likes (same article).

In the meantime, capacity went from 20 to 100, then 1,200, then 10,000 (Money Today, Nongmin Shinmun). Now 100 rooms named “Cheongyeondang” hold 100 people each. On the morning of the 30th, 4,679 people were sitting in those rooms, and five of them were full (Money Today). By 6 p.m. the same day, it was 5,119. People pour in around quitting time (Sidae Ilbo).

So the most common complaint at this temple isn’t about the quiet but about seats. “I logged in this morning and there were no seats.” “All 1,200 spots are full, is this for real?” “I couldn’t find a seat, so I’ve been standing this whole time” (cited by Money Today). Only one person can sit on each cushion (Nongmin Shinmun). A line formed in a room where nobody speaks.

The solo developer’s fix list follows the temple’s rules too. When users said the shared moktak sound everyone heard was distracting, he removed it and switched to a personal moktak. He blocked people from sitting on top of someone else’s cushion. Next up: sounds other than the Heart Sutra, better prayer beads and a bigger hall (Money Today). Even the features he adds protect time alone. What users ask for is similar: “How about we all sit around for a temple meal together?” (Yonhap News TV). They want a scene of eating together, but still a scene without words.

Within two days, a cathedral and a sauna followed

Once SANSA took off, look-alike virtual spaces poured out right away: an online cathedral, a church, a sauna, a campground, even a space set in outer space. Sidae Ilbo pointed out that it’s because AI now lets people build services like this in very little time (October 30). The online cathedral “Infis” is one of them (Etoday).

The stage was already set. Temples are so trendy among Korean twentysomethings that people talk about “hip Buddhism,” and in September, a restock of about 6,000 moktak-shaped “merit keychains” sold out in a single day at Seoul’s Bongeunsa Temple (Etoday, Hankyung Magazine). In Statistics Korea’s 2025 Social Survey, 38.2% of people aged 13 and older said they usually feel lonely (cited by HuffPost Korea). Where lonely people flocked wasn’t a chat room but a temple hall where talking is forbidden.

Copies can rebuild the shape of the hall in a day or two. A 3D room, characters and three buttons aren’t hard. At SANSA, the only thing users can do for each other is press their palms together, and the people who came to do just that turned a 20-seat hall into a 10,000-seat one.
