Share a config value with a link — no login

Sometimes you just need to hand one config value to one person — a teammate, a contractor, a client — without giving them an account, a dashboard, or access to your whole project. Nona does exactly that.

The problem

Traditionally, letting someone see or change a single config value means creating them an account, granting project access, and hoping they only touch the one thing. That is overkill, and it is a security risk. Nona treats "share one value with one person" as a first-class action instead.

How it works

1

Hit Share on any parameter

Every parameter has a Share action, right next to it. No separate setup, no config file — just click it.

Choose expiry and permission

Pick how long the link lives (1 hour by default, 1 day, or 3 days) and whether the recipient can view or edit the value. That is the whole configuration.

Send it — and revoke it anytime

Nona generates a cryptographically secure link. You see every active link for the parameter, when it expires, who made it, and a Revoke button to kill it instantly.

They open a minimal page — just that one value

The recipient sees only the parameter name, environment, and value. With edit access they change it and hit Save. No login, no dashboard, no access to any other parameter or project.

Secure by design

No account required does not mean careless:

  • Every link is scoped to exactly one project, environment, and parameter.
  • Tokens are cryptographically generated and stored as a one-way hash.
  • Every request re-validates the token, its expiry, and its revocation status.
  • You can revoke any link instantly, and expired or revoked links stop working immediately.
  • Create, access, edit, and revoke events are all written to the audit log — and edits are flagged as coming from a shared link, not an authenticated user.

Why no other config tool does this

Firebase Remote Config, LaunchDarkly, Unleash, Flagsmith — they all make you have an account and access to the project before you can touch a value. Nona is an open source, self-hosted remote config and feature flag service, and sharing a single value with a link is the kind of small, practical thing we built it to do well. It is also why we open sourced Nona.

Try it yourself

Nona is open source under the Apache 2.0 licence. Self-host it with Docker, and share your first parameter in a couple of minutes.
