Hashling compared
An honest look at how Hashling sits alongside Little Snitch, LuLu, Malwarebytes, Bitdefender AI Guardian, and Snyk Agent Scan. Every tool listed here is good at what it does. They cover different things.
No single tool does everything. Hashling watches your Mac broadly in plain words, connects your AI to your security, and checks your phone. It does not block network connections in real time (Little Snitch and LuLu do that). It does not intercept malware the moment a file arrives (Malwarebytes does that). It is aimed at people, not CI pipelines.
If the honest trade-offs below suggest you need a tool Hashling does not cover, pair them. Hashling works well alongside a firewall like LuLu.
| Feature | Hashling | Little Snitch | LuLu | Malwarebytes | Bitdefender AI Guardian | Snyk Agent Scan |
|---|---|---|---|---|---|---|
| Price | Free | ~$59 one-time | Free | Free scan; ~$39.99/yr for real-time protection | Free (public beta) | Free tier; $25+/user/month for teams |
| Open source | Yes (MIT) | No | Yes | No | No | Yes (Apache-2.0) |
| Runs fully on your Mac | Yes (your questions go only to the AI provider you choose; looks up IP owners online, can be turned off) | Yes | Yes | Yes (cloud reputation checks) | Mostly (some website reputation checks use Bitdefender cloud) | Yes (requires a Snyk account and API token) |
| Works with your own AI via MCP | Yes (Claude Code, Cursor, Codex, any MCP agent, or a free model running fully on your Mac) | No | No | No | No | Partial (MCP server for code scanning, not a full security overview) |
| Watches AI coding agents (Claude Code, Cursor, Codex, etc.) | Yes (permissions, MCP servers, keys in settings, live network use) | No | No | No | Yes (blocks risky agent actions, detects prompt injection; currently Claude Code and OpenClaw only) | Yes (scans MCP servers and agent components for vulnerabilities; CLI tool) |
| Scam check for texts, emails, and links | Yes | No | No | Partial (browser web protection blocks known phishing sites) | No | No |
| Firewall that blocks connections live | No (monitors only; pair with LuLu or Little Snitch) | Yes (per-app allow/deny with alerts) | Yes (per-app allow/deny) | No | No | No |
| Real-time malware blocking before a file opens | No (Hashling scans files shortly after they arrive and watches for mass-rename attacks) | No | No | Yes (quarantines threats in real time; tested by AV-Test, AVLab, MRG Effitas) | No | No |
| Plain-word explanations throughout | Yes (hover any label; Simple/Standard/Expert modes) | No (aimed at technical users) | No (minimal UI) | Partial (dashboard is clear; logs are technical) | Partial (developer-focused) | No (developer/team tool) |
| Phone check-up (cable: iOS and Android) | Yes (read-only; nothing leaves the Mac) | No | No | No | No | No |
| Needs an account | No account | License key required | No | Optional for free; account needed for premium | Account for beta access | Yes (Snyk account and API token) |
Each tool at a glance
Little Snitch
~$59 one-time license. Not open source.
Blocking outgoing connections in real time, per app. When an app tries to call home, Little Snitch stops it and asks you. It is the gold standard for network-level privacy on a Mac. Also shows a detailed Network Monitor with traffic history.
You want to control which apps can reach the internet and you are comfortable managing a list of connection rules. It pairs well with Hashling.
LuLu
Free. Open source (by Objective-See).
Blocking outgoing connections in real time, at no cost. Free alternative to Little Snitch from a trusted Mac security researcher. Fewer features, simpler UI, but the core firewall is solid.
You want live connection blocking for free. It pairs well with Hashling for broader visibility.
Malwarebytes for Mac
Free scan. ~$39.99/yr for real-time protection. Not open source.
Blocking malware the moment a file arrives, before it can run. Independently tested by AV-Test, AVLab, and MRG Effitas. Hashling scans files shortly after arrival using ClamAV, YARA-X, and Apple's own XProtect rules.
You want lab-verified, real-time malware blocking and do not mind a subscription. Malwarebytes does not watch AI coding agents or explain things in plain words.
Bitdefender AI Guardian
Free during public beta (launched 30 Sep 2026). Not open source. Future pricing not announced.
Intercepting and blocking individual AI agent actions before they run. AI Guardian acts as a gatekeeper between your AI coding agent and your Mac, blocking actions that break its policy. It also detects prompt injection attempts and verifies MCP tools before an agent calls them. Hashling watches and explains but does not block individual actions live.
You want a tool that actively blocks risky AI agent actions in real time. It currently supports Claude Code and OpenClaw only. It is in beta and future pricing is not announced.
Snyk Agent Scan
Free tier. $25+/user/month for teams. Open source (Apache-2.0). Requires a Snyk account.
Deep supply-chain scanning of MCP servers, agent skills, and prompts for known vulnerabilities, tool poisoning, and hardcoded secrets. Built for software teams that want to audit their agent infrastructure in CI and across an organization. Snyk's broader platform integrates with code reviews, dependency scanning, and container security.
You are a developer or a security team that builds or uses AI agents and wants automated, policy-driven scanning in your pipeline. It is not designed for end users or as a personal Mac security agent.
