Tabverse is a local first workona like chrome extension for managing tabs, with its source open at https://www.github.com/liyu1981/tabverse.
In essential it has the core functions workona has, but can operate totally locally, which means it will not need an account nor subscription. The only limit is your local storage spaces so that you can have as many spaces(I call tabverse) as you can. It is open source, so not just your data stays with you, and the tool itself will stay with you in future.
Beyond the normal workona features (persisted workspace, load/reload/import/export, note/bookmark/history tools), there are features does require a server. Features like backup/sync, global search on all tabverses, and future collaboration (not yet done), can only be possible if there is a server. I build this part in open too: the server is free to self host and open source in same repo of Tabverse.
The tabverse's idea was with me few years ago while I was using Workona and was frustrated with its limitation on free tier (remember was only 5 workspaces), and the missing features of managing multiple workspaces at the same time. Tabverse takes the idea of Workona, and develop further: each window with a Tabverse tab is a workspace, all stored in local storage, and multi windows can have multi Tabverses same time, and can switch fast. There can even be window without Tabverse, so besides work, personal stuff or entertainment will have place to go. As I build this alone, in the middle, almost give up on this project, and luckily AI agents now is there: not only I have a good helper, but also I have a partner I can discuss a bit. So this time the first version starts with v0.7.2.
But AI agent can never replace the real need from human on what should be built and what works better, so I want to share with you and listen to your feedbacks early. Please give it a try, and every feedback to me is a gift.
Besides the self-hosted option, I host a server at https://tabverse.liyu1981.xyz (yes, the same website of intro and docs), but is invitation only. If you want to help me to test in this early stage, you can login with Google (the only social login I configured :)), and request an invitation there. I will act as soon as I find your request :). But do not worry at all if you only want to use Tabverse locally without a server -- that is the first thing when I was building it.
In current version there are also AI features built in, and again do not worry as the AI features is using Chrome's Prompt API, which is totally local, with Gemini Nano (first time will need to download it automatically), nothing send to a server, and you can always turn this on of off in settings. Morden computers with decent memory should work well, but some older computer may suffer (so please turn off). And it is Chrome only. (Honestly, Tabverse currently only support Google Chrome, but not other Chrome based browsers).
