Bonsai Browser bets programmers pay for a research browser; archived 2022
Two founders built Bonsai, a Mac browser for research workflows; after a 1,070-point HN launch, the repo was archived in Dec 2022.
Bonsai Browser
What the business is
Bonsai Browser is a two-person, Mac-first Electron web browser for programmers and researchers: a hotkey summons it over the IDE, tabs group by domain, and history is stored as a back-linked tree feeding spatial workspaces.
How it started
Cameron and a co-founder first tried to build a citation manager for a Chrome-to-Zotero-to-Emacs research workflow, but conversations with PhDs and postdocs showed every researcher organizes differently. A friend's trouble finding 'cloud documents' pushed them toward a spotlight-style file finder, which already existed. They concluded the browser itself was the bottleneck: research browsing mixed with ordinary web use 'creates a mess', so they built a full browser instead of an extension, which they said would only add noise.
What happened
The 2021-09-07 Show HN grew to 1,070 points and 226 comments. Users praised the spatial organization and tree history but pressed the founders on closed source, missing extension and password-manager support, Electron performance and the Mac-only release. In reply the founders laid out a JetBrains-style perpetual license around $50, possibly free later if paid server features emerged, open source if a community formed, and Linux and Windows builds 'less than a month' away. The repository's later configuration shows the project kept shipping — user accounts (Supabase), analytics (Mixpanel) and Apple notarization were added from November 2021 — before the repo moved to the Bonsai-Desk organization.
How it ended up
The distribution repository github.com/hyferg/bonsai-browser-public, by then Bonsai-Desk/bonsai-browser, was archived by its owner on 2022-12-20 with a README stating 'Bonsai Browser is no longer being actively developed'; no funding, revenue or user numbers were ever disclosed in the launch thread.
Background
Bonsai Browser was a two-person bet that the browser, not the researcher, was the broken part of online research. Cameron and his co-founder first tried a citation manager for a Chrome-to-Zotero-to-Emacs workflow, but conversations with PhDs and postdocs convinced them no single tool would fit every workflow; a cloud-document search idea turned out to already exist. Their conclusion was that research browsing mixed with ordinary web use 'creates a mess', so they built a full Mac browser rather than an extension, which they argued would create more noise.
The product organized browsing like a workspace: a hotkey summoned it over the IDE, tabs grouped by domain, and history was stored as a tree showing how pages back-link to each other and to spatial workspaces, with open tabs and saved pages both pointing into that tree. The founders launched Mac-only because they used Macs and could catch bugs faster, distributed the app through GitHub releases to avoid download bandwidth bills, and promised Linux and Windows builds in less than a month.
The Show HN on 2021-09-07 drew 1,070 points and 226 comments, and the founder reported about 1 TB of website traffic in a day and 2.2 TB of Netlify transfer by the time of the thread. Enthusiasm was real but conditional: commenters praised spatial organization while pressing on closed source, the lack of extension and password-manager support, Electron performance and the Mac-only release. In reply the founders described a JetBrains-style perpetual license around $50, a possible free browser later if paid server features emerged, and open source if a community formed.
The project kept building after launch — the repository's later configuration shows user accounts (Supabase), analytics (Mixpanel) and Apple notarization added from November 2021 — before the repo moved to the Bonsai-Desk organization. The distribution repository was archived by its owner on 2022-12-20 with a README stating the browser was 'no longer being actively developed'. No funding, revenue or user figures were ever disclosed.
What has to be true
- The pain was real and articulated: research browsing mixed with ordinary tabs creates clutter, and linear tab lists fail once a user holds hundreds of pages.
- A full browser, not an extension, let the team rethink history as a tree and organize pages spatially — the ideas the HN crowd praised most.
- Mac-first gave two founders a testable slice, and GitHub-release distribution kept a 1 TB launch day from turning into a bandwidth bill.
- The launch validated desire but exposed the deal-breakers — closed source, no extensions, Electron overhead — that a two-person team could not fix fast enough.
What can be applied
A 1,000-point launch proves desire, not a business: users balked at closed source, missing extensions and Electron's heft, and two people could not beat browser ecosystem lock-in.
Aftermath
As of 2026-09-05 the product is closed: the distribution repository, hyferg/bonsai-browser-public (later under the Bonsai-Desk organization), was archived by its owner on 2022-12-20 and its README says Bonsai Browser is no longer being actively developed. The 2021 launch thread disclosed no funding, revenue, effective pricing or user counts, and this material contains no record of a relaunch or acquisition.
