OBSCURA OS
Zero-account browser OS for privacy, freedom & journalism
What it does
OBSCURA OS is a full workspace (docs, sheets, slides, notes, calendar) that runs 100% in your browser — zero accounts, zero cloud. For journalists, activists, and anyone whose safety depends on not being tracked, that means no login to subpoena and no server to breach. The Sovereign Suite adds real counter-forensics tools: PDF redaction, leak detection, steganography, secure data splitting. Free to start; $9 one-time unlocks the full Sovereign Suite.
Sovereign, Zero-Account Browser Operating System: Private Workspace Suite and defensive Sovereign Suite with 100% client-side memory execution.
Documents, spreadsheets, slides, notes and a suite of privacy tools that run entirely inside this browser tab. Nothing is uploaded, because there is nowhere to upload it to. No account, no password, no company reading your work to sell you something. Why we built it this way → Every office tool you use today is a rented seat on somebody else's server. Your documents, your contacts, your client files: all readable by the company that hosts them, and all one policy change away from being mined, trained on, or handed over. OBSCURA OS puts the tools back on your own machine. Nothing is uploaded, because there is nowhere to upload it. Nothing is read, because nobody else can see it.…from obscuraos.com

Hello HN, I've been working solo on Octelium for the past 5+ years now, (yes, you just read that correctly :|) along with a couple more sub-projects that will hopefully be released soon and I'd love to get some honest opinions from you. Octelium is simply an open source, self-hosted, unified platform for zero trust resource access that is primarily meant to be a modern alternative to corporate VPNs and remote access tools. It is built to be generic enough to not only operate as a ZTNA/BeyondCorp platform (i.e. alternative to Cloudflare Zero Trust, Google BeyondCorp, Zscaler Private…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
