Comparison
CitrusGlaze vs Harmonic
Harmonic monitors AI usage at the browser layer. CitrusGlaze sees everything — CLI tools, SDKs, agents, and the secrets hiding in all of them.
| Feature | CitrusGlaze | Harmonic |
|---|---|---|
| Approach | Local MITM proxy | Browser extension + API |
| Data routing | 100% local | Cloud-processed |
| CLI tools (Claude Code, Cursor) | Yes — 39+ verified | No (browser only) |
| Agent/SDK traffic | Yes — all processes | No |
| Secret detection | 254+ patterns (Rust) | Content classification |
| Token/cost tracking | Yes — per request | Limited |
| Real-time blocking | Yes — at network layer | Coaching/warnings |
| Deploy time | 5 minutes | Hours (browser deploy) |
| Price | $10/user/month | Custom (sales call) |
Where Harmonic wins
User coaching
Harmonic focuses on "safe enablement" — real-time coaching that nudges users away from risky behavior rather than hard-blocking. If your priority is behavioral change over enforcement, Harmonic's approach is gentler.
Content classification
Harmonic uses LLMs to classify prompt content — identifying source code, PII, financial data, and proprietary information by understanding context, not just pattern matching. This can catch sensitive data that isn't a credential.
Easier rollout for non-technical users
A browser extension is simpler to deploy across non-technical teams than a proxy. If your main concern is marketing, sales, or support teams using ChatGPT in the browser, Harmonic's extension model is lower friction.
Where CitrusGlaze wins
51% of AI traffic is invisible to Harmonic
Harmonic only sees browser-based AI usage. It cannot see Claude Code, Cursor, GitHub Copilot, pip, npm, or any AI SDK making API calls from a terminal or script.
Our telemetry shows 51.4% of AI traffic comes from programmatic sources — CLI tools, SDKs, and agents. Harmonic misses all of it.
If your developers use coding assistants (they do), Harmonic has a blind spot that covers more than half your AI traffic.
Hard blocking, not just coaching
Harmonic warns users. CitrusGlaze blocks secrets at the network layer before they reach the AI provider. The request never leaves your machine.
Coaching helps with behavioral change. Blocking prevents the AWS key from being sent to OpenAI. Both matter — but if the key is already in the prompt, only one stops the leak.
Data stays on your machine
Harmonic processes prompt content in their cloud for classification. CitrusGlaze scans everything locally.
If you're scanning for secrets in AI prompts, sending those prompts to another cloud service for analysis is... ironic.
Agent and automation coverage
AI agents run autonomously with your credentials. They make API calls from scripts and processes — no browser involved. Harmonic can't see any of this.
CitrusGlaze sits at the network layer and catches every AI API call from any process. Tool calls, function invocations, credential usage — all visible.
