Firejail is a SUID program that reduces the risk of security breaches by restricting the running environment of untrusted applications using [Linux namespaces](https://lwn.net/Articles/531114/) and [seccomp-bpf](https://l3net.wordpress.com/2015/04/13/firejail-seccomp-guide/).
Best alternatives to Grith in 2026
Letting an AI coding agent run commands on your machine is convenient right up until it does something you didn't expect, deletes a file, reads a secret, or reaches out to a server it shouldn't. Grith sits underneath the AI agent at the operating-system level and checks every action before it happens. Grith is an OS-level security supervisor for AI coding agents, including Claude, Codex, Aider, Cursor, Cline, and Copilot, that intercepts Linux system calls, scores each action against 18 built-in security filters covering secret scanning, sensitive-path detection, egress policy, destructive-operation checks, and taint tracking, and automatically allows low-risk actions, queues ambiguous ones for human review, and denies high-risk ones, all through a single wrapper command with no agent-specific integration required. It keeps a hash-chained audit log and can run fully offline. MPL-2.0 licensed, freemium.

macOS app that intercepts and audits MCP server traffic between Claude Desktop or Cursor and connected tools for security oversight.
- ✓ Purpose-built for MCP, not a repurposed generic tool
- ✓ Free, open-source option under GPL-3.0
Free, in-browser generator for robots.txt and llms.txt files that control which AI crawlers can access your site.
- ✓ 100% client-side — no account, no data leaves your browser
- ✓ Covers 82+ named AI crawlers with sensible presets
Privacy-first browser side panel AI assistant that works with any model or agent and anonymizes sensitive data before it leaves your browser.
- ✓ Works with any AI model or agent — in-browser, local, cloud API, or coding agents like Claude Code/Copilot
- ✓ Anonymizes sensitive data (emails, phone numbers, card numbers) before it leaves your browser, restores it in the reply
Open-source, developer-first privacy and cookie-consent infrastructure with headless consent flows and version-controlled policies.
- ✓ Fully open-source (Apache-2.0) with a public commitment to never relicense or paywall features
- ✓ Lightweight headless consent engine (under 4kb core)
Open-source WireGuard-based mesh VPN that replaces traditional VPNs with Zero Trust, identity-based device access.
- ✓ Open-source (BSD-3-Clause + AGPLv3) with 28.9k GitHub stars and active development
- ✓ WireGuard-based peer-to-peer mesh is faster and simpler than routing through a central VPN gateway
Invisible, privacy-first bot protection using proof-of-work instead of visual puzzles.
- ✓ Invisible — no puzzles, no user friction
- ✓ GDPR-compliant by design, zero personal data collected
Enterprise policy-enforcement layer that watches what coding agents do — prompts, commands, file changes — and blocks or alerts on sensitive data exposure.
- ✓ Visibilité temps réel sur les actions des agents IA
- ✓ Détection/blocage de données sensibles et credentials
Authorization layer that checks every AI agent action against a policy before it runs, with per-action revocation and a full audit trail.
- ✓ Vérification par action, pas seulement par clé API
- ✓ Révocation ciblée sans tuer tout le processus
A free Python command-line tool that checks a website's HTTPS certificate and tells you exactly what's wrong with it — expired, untrusted, wrong hostname — instead of a generic connection error.
- ✓ Zero dependencies, easy to drop into bare servers or containers
- ✓ Detailed diagnostics rather than a generic 'connection failed'
An open-source trust-boundary gateway that sits in front of OpenAI, Anthropic and Gemini API traffic to redact PII, enforce rate limits, and track usage without touching your app code.
- ✓ Single gateway covering OpenAI, Anthropic and Gemini without SDK changes
- ✓ Comprehensive PII detection and redaction
