Octave Online

Octave Online is a web interface for GNU Octave, presented on its home page as an open-source alternative to MATLAB. Users type commands at an online Octave prompt as they would in a local copy of Octave or MATLAB, and charts and graphs display in the browser. People who sign in can create and edit script files, share work through buckets, projects and real-time collaboration, and track revisions with Git.

The service is free to use, with optional Patreon support suggested at US$3 per month and extended runtime for upgraded accounts. The operator is Octave Online LLC, the server code is licensed under AGPL, and the agreement is governed by the laws of Missouri. The company's country of establishment is not stated on the pages we read.

• Online Octave prompt. Commands are typed into a prompt in the browser, the same way as in a local Octave or MATLAB session. Nothing needs installing, which suits a quick calculation on a machine you do not control.
• Browser charts. Charts and graphs appear in the browser. The home page also lists an option called Render New Plots Inline, so figures can sit within the console output.
• Script files for signed-in users. Signed-in users can create and edit script files. Those files are deleted after six months of inactivity, which matters for anyone treating the service as long-term storage.
• Buckets and projects. Buckets are shareable snapshots of scripts and data, while projects are editable workspaces. The two cover handing out a fixed example and working on a live copy.
• Real-time collaboration. The home page names real-time collaboration as a sharing feature. How many people can edit at once is not stated on the pages we read.
• Git revision tracking. Revisions to files are tracked by a Git version control system. Users can also request a ZIP archive of their files by email, which is the only export route the home page describes.
• Session countdown. A Seconds Remaining counter shows how long the session lasts. The home page gives no session length, memory limit or numeric file size limit, only that files too large cannot be loaded into the editor.

• A student on a laptop without Octave. Running course exercises written for MATLAB syntax in the browser. Scripts saved after signing in are kept, unless the account sits idle for six months.
• A tutor sharing a worked example. Publishing a bucket containing a script and its data so learners can open a snapshot. A project suits a group that wants to edit the same files together.
• An engineer testing a snippet. Checking a short numerical routine while away from a workstation. Longer jobs run into the session countdown, and extended runtime is tied to upgraded accounts.

Open the home page and start typing at the Octave prompt; the page describes no registration step for basic use. Signing in is what unlocks saved script files, buckets, projects and real-time collaboration, and the page lists options such as Render New Plots Inline and Wrap Long Lines in Console.

Watch the Seconds Remaining counter, because the session has a time limit whose length the page does not state. Anyone who wants more runtime can support the service through Patreon. A ZIP archive of files can be requested by email, which is worth doing before an account goes six months without activity. The pages we read give no tutorial for Octave itself.

Octave Online puts a GNU Octave prompt in the browser, so nothing is installed. Signed-in users get script files, shareable buckets, editable projects and Git-tracked revisions.

Limits matter for serious work: script files are deleted after six months of inactivity, a countdown shows seconds remaining in the session, and files that are too large cannot be loaded into the editor. The operator is Octave Online LLC.

In our numerical computing software ranking Octave Online stands at #8 of 13: the products next to it are PARI/GP above and Mathics below. From place 4 the established names follow in their ranked order; we publish no numeric score.

The vendor states no country of establishment, so Octave Online is left out of the regional count for this list.

Charging model: Free to use online; optional Patreon support for extended runtime, tiers not listed.

The home page says the service is free to use. It also offers optional Patreon support, with a suggested US$3 per month, and says upgraded accounts get extended runtime. The tiers are not listed on the pages we read, so what exactly each level adds beyond runtime is unknown. The privacy policy mentions the monetisation provider Publift and Google Analytics, which suggests advertising plays a part in funding, though the pages do not spell out the business model. Prices are in US dollars. No team, education or enterprise plan is described, and no invoice or billing terms appear on the pages we read, so organisations that need a contract would have to ask the operator.

Storage sits on Google Cloud Platform in Council Bluffs, Iowa, with backup copies possibly kept elsewhere, and the privacy policy says files and transcripts may be kept indefinitely while full deletion needs a support request.

A ZIP of files can be requested by email.

Cookies, Google Analytics and the monetisation provider Publift are in use, and the company's country is not stated.

The privacy policy says information is stored on Google Cloud Platform based in Council Bluffs, Iowa, USA, with backup copies possibly kept in other unspecified locations. Files and transcripts may be kept indefinitely, and fully deleting a file requires a support request.

Cookies keep users logged in, Google Analytics is used, and the service works with Publift. The policy does not mention encryption or a data export right, and it names no country, state or street address for Octave Online LLC. The home page says the agreement is governed by Missouri law. The server code is licensed under AGPL and linked on GitHub.

Four tests decide a position: how soon the product is useful, what the bill really becomes, how data leaves and who it suits. That puts Octave Online at #8 of 13. How vendor facts are sourced, and how money can and cannot influence a page, is in the editorial process.
