01 · Investigation Brief
Investigation Brief
Herdr.dev is the landing page for an Apache-2.0-licensed background terminal service that keeps coding-agent sessions alive across restarts. The site is backed by Y Combinator, shows 34 k GitHub stars, and offers a single one-line install command; no affiliate upsells, subscription traps, or credential-harvesting forms are present.
Project legitimacy and technical profile
The page describes Herdr as a background server that keeps agent terminals running even when the laptop lid is closed or the network drops, then restores sessions on restart.
It explicitly lists compatibility with Claude Code, Codex, Cursor, opencode, Grok and similar tools, and states it is released under the Apache 2.0 license with the repository at github.com/herdrdev/herdr.
Risk assessment
The hosting IP carries a 0/100 abuse score with no prior reports, and the only commercial action shown is a copyable one-line curl command that downloads an install script from the same domain.
No cross-domain checkout, subscription prompt, wallet connection, or data-collection form is visible; the only external links are to the project’s GitHub and X accounts.
Why the score is 92
The score combines saved deterministic evidence with the grounded analysis available for this report. Coverage remains separate so missing sources cannot be mistaken for clean results.

Domain & infrastructure
The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.
