Harden
Local-first security layer that checks coding-agent tool calls before they run — free for individuals.
Local-first guardrails that inspect coding-agent actions before they run — free open-source CLI.
Why on the board
Verified live 2026-09-22. Product Hunt launch 2026-09-09 — new agent-firewall product, not a years-old brand.
What it is
Harden (harden.run) markets an Agentic Integrity Foundation: local-first guardrails that inspect coding-agent tool calls before they execute, plus scanning aimed at “vibe-coded” apps before release. From schema and FAQ content we pulled on a live HTTP 200 page (2026-09-22): they describe checking dangerous actions pre-execution, finding issues like hardcoded secrets / missing auth / uncontrolled egress, and generating compliance-ish artifacts (e.g. SBOM, audit logs). The CLI is positioned as open source and free forever; fleet dashboard, approval gates, and compliance reporting sit on enterprise/custom pricing. Contact domain on the page references vizops.ai.
Who it’s for
Individuals and teams letting Cursor/Bolt/Lovable/Replit-class agents touch real repos or deploy paths who want a stopgap before “the agent deleted prod.” Security-minded makers shipping AI-written apps into anything resembling a customer environment. If your agents only edit throwaway sandboxes, you may not feel the pain yet.
Why we listed it
Product Hunt launch 2026-09-09; live site verified 2026-09-22. New agent-firewall product — not a multi-year household brand. Fits the board’s freshness rule and the maker question “who watches the coding agent?”
Caveats
The marketing site is heavily client-rendered; we relied on structured FAQ/SoftwareApplication data plus the live response, not a full interactive trial write-up. “Free forever CLI” vs enterprise upsell is a classic open-core shape — confirm license and what actually runs local vs cloud. No security tool is a substitute for review on high-impact changes. We have not audited their detection quality.
