EnglishIs Kyso still available after its shutdown?
Updated
No. The hosted Kyso platform is gone. According to Kyso's own site, "Kyso - the universal aggregator for all research formats was shut down on September 31, 2023." The same page states that Kyso is now open-source, with the code available through a GitHub project linked from the site. So the answer depends on what you mean by "Kyso": the online service is no longer available, but the codebase can still be obtained and run by anyone willing to host it themselves.
What Kyso was
Kyso launched in 2018 as a platform for sharing data science work. Its original focus was Jupyter Notebooks, offering cloud-based compute environments and a reporting frontend. The team later built a public Jupyter-based blog that at one point had over 60,000 monthly readers.
Over time, the scope widened. Kyso's team described the underlying problem this way: data science work spans many roles that use code and data to produce results, but those teams are spread across a wide variety of tools, even inside a single organisation. With no central hub to document and share results regardless of source or format, output ends up scattered across applications, collaboration stays in small private channels, and long-term discovery suffers. Kyso positioned itself as a "universal aggregator for all research formats" to address that gap. The team noted that Stripe and Airbnb built internal solutions to the same problem, and that Spotify and Netflix were working on similar in-house aggregators.
What happened
The platform shut down on September 31, 2023, as stated on the Kyso site. The team's note frames the decision around the difficulty of serving a tooling ecosystem that extends well beyond Jupyter notebooks, and around the value that gets lost when knowledge is not documented and searchable.
Note that the shutdown date as written on the site is internally inconsistent — September has 30 days, so "September 31" is not a real calendar date. Treat the month and year as the reliable part of that statement.
What replaced it: the open-source project
The site's headline is "Kyso is now open-source!" and it points readers to a GitHub project for the code. The page also links to GitHub and GitBook resources.
The key distinction for anyone deciding what to do next:
| Hosted Kyso (before shutdown) | Open-source Kyso (now) | |
|---|---|---|
| Availability | Online service, now discontinued | Code obtainable via GitHub |
| Who runs it | Kyso | You or your team |
| Compute environments | Provided by the platform | Not provided by Kyso; you supply your own |
| Maintenance | Handled by Kyso | Handled by whoever deploys it |
| Best for | Users who wanted a ready-made hosted product | Teams able to self-host and maintain software |
Who the open-source version suits
The open-source route makes sense if you have the engineering capacity to deploy and maintain a self-hosted service, and if the aggregator concept — pulling research output from multiple tools and formats into one searchable place — matches a problem you already have. It is a reasonable fit for teams that were already evaluating internal knowledge hubs, or that want to study how Kyso approached the problem.
It is a poor fit if you just want an online account to publish notebooks. That product no longer exists, and the open-source project does not come with Kyso's hosted compute or support.
Practical next steps
- Go to the Kyso site and follow the GitHub link under "Kyso is now open-source!" to reach the current repository.
- Check the repository's README and any linked GitBook documentation for setup requirements before committing to a deployment.
- Confirm what infrastructure you will need to provide yourself, since the hosted compute environments are not part of the shutdown-era service.
- If self-hosting is not realistic for your team, treat Kyso as a case study rather than a tool, and evaluate currently maintained alternatives against the same requirement: one searchable hub across mixed research formats.
