Built for temporary hand-offs. Designed to forget.
Sharelinknow is an ephemeral utility for bundling links, code snippets, and plain text notes behind a single, anonymous six-character pickup code. No accounts, no user tracking, and no permanent data retention.
The friction of permanent platforms
Most modern collaboration tools are designed for perpetual storage. When you need to send a temporary URL, an API snippet, or a configuration note to a colleague, another machine, or a temporary partner, you are frequently forced to:
- Create an account with an email address and strong password.
- Authenticate through third-party social or enterprise identity providers.
- Leave sensitive or transient information permanently indexed in chat histories, email threads, or cloud drives.
Sharelinknow was created to eliminate this friction. We treat temporary information as truly temporary: bundle what you need, deliver the pickup code, and let the data expire automatically.
Who uses Sharelinknow
Software Engineers & Sysadmins
Move configuration snippets, SSH public keys, terminal logs, and staging URLs across distinct devices, test servers, or virtual machines without cluttering corporate message channels.
Writers, Researchers & Students
Organize reference links and research citations into a structured slip to hand off between desktop workstations, tablets, or shared laboratory terminals.
The hand-off mechanics
Compose the slip
Add up to 40 items across links, formatted code blocks with syntax hints, and markdown notes (up to 256 KB total payload).
Set lifecycle and protection
Select an expiration interval (1 hour, 24 hours, 7 days, or 30 days). Optionally set a ticket password, which is hashed with scrypt before storage to guard sensitive contents.
Hand off the pickup code
Share the six-character alphanumeric code or direct retrieval link. The recipient enters the code to unlock and view the bundled items.
Automated deletion
When the expiration timestamp is reached, the database row is deleted. Subsequent retrieval requests receive an explicit 410 Gone response.
Field Notes: Engineering & Design Publications
Beyond our core utility, we maintain Field Notes, an educational engineering publication. Field Notes documents our architectural decisions, investigations into modern web protocols, cryptographic best practices, and the challenges of building high-performance, minimalist web applications using Next.js, TypeScript, and relational databases.
Our articles focus on practical technical concepts: implementing constant-time credential verification, managing stateless HMAC-SHA256 session lifecycles, preventing cross-site request forgery, and designing responsive interfaces free of intrusive third-party scripts.
Commitment to transparency and privacy
Our operational principles are straightforward:
- Zero public accounts: We do not ask for names, email addresses, or telephone numbers to create or retrieve tickets.
- No data harvesting: We do not sell, rent, or trade payload contents or visitor metadata.
- Responsible disclosure: We welcome constructive technical audits and peer feedback through our Contact page.
