Coko

What Coko does

Coko Foundation was a San Francisco-based not-for-profit organization, founded in 2015 by Adam Hyde with seed funding from his Shuttleworth Foundation Fellowship, that built open-source, HTML-first publishing infrastructure for the scholarly, research, and educational publishing ecosystems. Its core technology stack — built on Node.js, React, and GraphQL — was anchored by the PubSweet/CokoServer component-based framework and included the Kotahi journal publishing platform, Ketty (formerly Editoria) book production platform, Paged.js browser-based typesetting engine, XSweet/INK document conversion tools, and the Wax web-based word processor. The architecture's central thesis was that HTML-first, single-source publishing enabled synchronous, concurrent collaboration in a way traditional XML workflows could not, allowing books to move from draft to publication in five days or less.

Coko operated a partner-driven, community-led GTM rather than a commercial sales motion: it co-developed platforms with organizations such as EBI, eLife, Hindawi (later acquired by Wiley, with Phenom now serving as the backend of Wiley's REX platform), the California Digital Library, HHMI, Caltech, DataCite, and the Louvre, and shipped products as 100% open-source with no proprietary dependencies. Funding came primarily from foundation grants — Shuttleworth, Mellon, Gordon & Betty Moore, Alfred P. Sloan, and Laura & John Arnold — rather than commercial revenue. Headcount scaled in an accordion-like pattern, peaking at approximately 40 people during 2020-2023 when AI capabilities (AI Designer, RAG knowledge base, AI Assistant) were also layered into the platforms.

In 2024-2025, the Coko Foundation announced it is sunsetting operations, with founder Adam Hyde moving on to other projects and all products (Ketty, Kotahi, Paged.js, XSweet) being transitioned to independent not-for-profit stewardship while remaining permanently open source. Kotahi is becoming a standalone 501(c)(3) foundation, and Ketty is progressing on a similar path.

Core offering

Coko Foundation develops and maintains a suite of open-source, HTML-first publishing technologies for academic journals, books, and document conversion. Its offering spans a component-based framework (PubSweet/CokoServer), full publishing platforms (Kotahi for journals, Ketty/Editoria for books), a browser-based typesetting engine (Paged.js), a document conversion engine (XSweet/INK), and a web word processor (Wax), with AI design and RAG-based assistance features integrated into the platforms. Products are delivered as open-source software under not-for-profit stewardship rather than as commercial licenses.

Product overview

Coko Foundation developed a suite of open-source publishing technologies including Kotahi (journal publishing), Ketty/Editoria (book production), Paged.js (web-based typesetting), XSweeet (document conversion), and PubSweet/CokoServer (framework for building publishing platforms). The portfolio also includes Wax (word processor), Micropubs, Assessment Builder, and the DataCite Citation Corpus Platform. All products are built on HTML-first, open-source principles with a component-based architecture enabling collaborative, concurrent workflows. The foundation is currently sunsetting, with products moving to new not-for-profit stewards.

• EBI (European Bioinformatics Institute)coreStrategic or Co-development PartnerEarly partner in PubSweet collaboration. Formed early partnerships with Coko, EBI, eLife, and Hindawi who met regularly to design and build PubSweet together. Built EPMC+ platform which remains in active use.
• eLifecoreStrategic or Co-development PartnerEarly partner in PubSweet collaboration. Paul Shannon from eLife was deeply involved from early days, actively shaping how and what was built. Built first iteration of Libero components.
• HindawicoreStrategic or Co-development PartnerEarly partner in PubSweet collaboration. Andrew Smeall from Hindawi was early collaborator. Built Phenom platform which was later acquired by Wiley and is still in use as backend of Wiley's REX platform.
• CDL (California Digital Library)coreStrategic or Co-development PartnerPartnered with CDL and Mellon Foundation to build Editoria, the book production platform. Editoria has since been rebuilt as Ketty and is thriving.
• Digital SciencenotableTechnology or IntegrationBuilt a recomposable workflow platform on top of PubSweet. The platform stood out for allowing users to design workflows visually using a diagrammatic interface and compile those workflows into fully functional publishing platforms.
• HHMI (Howard Hughes Medical Institute)notableStrategic or Co-development PartnerPartner for Biointeractive Assessment Builder - still in active use.
• DataCitenotableStrategic or Co-development PartnerPartner for DataCite Citation Corpus platform - in active use.

Expansion highlights4 records

Direct peers

• Stencila: Open-source reproducible publishing platform using a ProseMirror-based word processor, explicitly cited in the data as having made the same architectural move away from Substance/Texture as Coko. Direct peer for collaborative authoring and reproducible scholarly publishing.
• Open Journal Systems (PKP): Public Knowledge Project's flagship open-source journal management and publishing software, the dominant incumbent in open-access journal platforms. Direct peer to Kotahi with the largest installed base of any open-source journal system.
• Manifold Scholarship: Open-source scholarly publishing platform from the University of Minnesota Press serving monographs and journals. Direct competitor to Kotahi for journal workflows and Ketty for book production, with shared mission of reducing publishing costs for academia.
• PubPub: Open-source community-led platform for academic and book publishing built around collaborative authoring and versioning. Direct peer to Kotahi and Ketty in the open scholarly publishing tools space, with overlapping target users (researchers, scholarly societies).
• Substance: Open-source collaborative document editor and publishing infrastructure originally developed with European funding. Direct peer to Coko's Wax/PubSweet and a former Coko collaborator that shared the Substance/Texture architectural lineage.

Broad incumbents

• Silverchair: Platform provider for society and academic publishers across journals, books, and reference works. Broad incumbent offering integrated publishing infrastructure that competes with the combined Kotahi/Ketty/Paged.js proposition.
• Wiley: Major commercial publisher that acquired Hindawi and now runs the REX platform on the Phenom codebase originally co-built with Coko. Comparable as a publishing customer and now as the operator of technology Coko helped create.
• HighWire Press: Long-standing scholarly publishing technology provider (JSTOR, NEJM, AMA) now part of MPS Limited. Broad incumbent in journal hosting and publishing platforms, with overlapping institutional customer base to Coko's platforms.
• Atypon Literatum: Commercial scholarly publishing platform provider serving major society publishers and university presses (Wiley, Sage, APA). Broad incumbent competing against Coko's publishing platforms for the same institutional customers with a much larger feature set and commercial support model.

Others

• eLife: Open-access journal publisher and a former Coko partner that built its Libero components via PubSweet. Comparable as an open-access scholarly publisher that has also invested in publishing technology and worked closely with Coko's ecosystem.
