Jane Manchun Wong is the researcher who made "it was in the code" a reporting beat. Working from Hong Kong and later San Francisco, she reverse-engineers the public builds of the world's biggest apps — Twitter, Instagram, Facebook, Snapchat, Spotify, LinkedIn, and more — to surface features the companies have not announced, publishing screenshots and mock-ups under her handle @wongmjane. The BBC called her "the woman scooping Silicon Valley"; MIT Technology Review called her work keeping tech "on its toes"; Casey Newton put it plainly: "there's no such thing as a secret beta anymore."
Origins and method
Wong was born in British Hong Kong in April 1994 and grew up there, a self-taught coder whose origin story is a seven-year-old replacing Windows with Linux to defeat parental controls. She studied computer science at UMass Dartmouth but left a few months before graduating because of medical issues — a decision she has said she regrets. Her method needs no insider access: she decompiles shipped mobile apps and reads public client-side code for dormant, flag-gated features, then documents what she finds. When the finding is a security risk rather than a feature, she routes it through bug-bounty programs first — her April 2020 write-up on reporting a private-API abuse path in the unreleased Messenger Rooms is the canonical example.
The scoop era
Her first documented discovery came in October 2017 — a Facebook résumé feature, surfaced via Matt Navarra — and her first self-posted "finding" followed on May 4, 2018: "Twitter is working on End-to-End Encrypted Secret DM!" What followed was a near-daily feed of discoveries that became infrastructure for tech journalism: Facebook Dating's homepage and a nearby-friends map in 2018, Instagram's hidden like counts in April 2019 (confirmed by Adam Mosseri about twelve days later), dark modes across apps, Twitter's tipping feature, and in May 2021 the name, price, and feature set of Twitter Blue weeks before launch. By October 2019, CNBC reported that Facebook employees themselves watched her feed to learn what other teams were building. Engineers began leaving "Hi, Jane" messages in code; one Instagram experiment was literally named "What's up Jane." The work was not free for her: she has described depression, harassment, and being treated as "an emotional punching bag" by users angry at features she merely reported. Recognition accumulated anyway — Tatler's Gen.T list in 2020, Forbes's 30 Under 30 (2022, Social Media) announced December 2021, and the MIT Technology Review profile in April 2022.
The Meta chapter
In June 2023 she crossed the wall: she joined Meta to work on Instagram and Threads — the flagship app of a company whose roadmap she had spent years leaking — relocating to San Francisco and announcing it on Threads on launch day, July 5. The hire was celebrated publicly by CTO Andrew Bosworth (already reportedly a member of Meta's internal Jane Manchun Wong fan club) and Instagram head Adam Mosseri. As a Threads team member she shared in the product's 2024 Webby win for Best Mobile User Interface. The chapter ended on October 16, 2024, when a Meta reorganization eliminated her role alongside cuts at Instagram, WhatsApp, and Reality Labs. Weeks later she announced a senior software engineer role at an unnamed Los Angeles startup — a post now unavailable, its date inconsistent even within Wikipedia.
After Meta
The hiatus ended loudly. In April 2025 she surfaced Figma's in-development Claude-powered AI app maker and "Figma Sites." In December 2025 she published her most technically striking disclosure: the complete 1,200-line system prompt for Waymo's unreleased Gemini ride assistant, recovered from the public app build — proof her method generalizes past social apps. By mid-2026 she had turned it on her own city, building a "radar" that scans San Francisco permits, business registrations, and health filings to scoop restaurant and retail openings — the Animate pop-up in Japantown, Stella Wang's Numb, the Corgi Cafe site — and telling the San Francisco Standard she has not ruled out shipping it publicly. A Twitter design patent granted in 2023 even cites her tweeted screenshot as prior art: the legal record now treats her findings as part of the state of the art.
What she says it means
Wong insists her work is not leaking — "leaks" come from employees, she says, while she reads "publicly available data and code." The mission, in her telling, is transparency: people who use these apps deserve to know what is being built behind the scenes, and "if they had been [transparent] before, I wouldn't have to do this." She also insists it is not the point of her life: she has wanted to be a software engineer since age six, wants to create things, and has said she will stop when her curiosity is satisfied.
What the record does not settle
The profile trail contradicts itself on her birth year (1994 by her own account; reported ages implying 1995–96). Her Meta title is variously reported. Her current employer is unconfirmed, with her own bio now listing "startups" in the past tense. This index preserves those seams rather than smoothing them.
