Why TokenGuard

One control layer for every AI project.

TokenGuard gives founders and teams the missing financial safety layer between their apps and OpenAI.

Budget guardrails

Set daily and monthly limits per AI project. TokenGuard blocks runaway usage before it becomes a surprise bill.

Proxy keys per project

Create a TokenGuard key for each app, client, environment, or team without exposing your real OpenAI key.

Live usage dashboard

Track requests, models, tokens, spend, latency, and recent logs from one clean dashboard.

Model fallback control

Route to a cheaper fallback model when budgets reach warning levels, keeping your app online.

Drop-in OpenAI compatible

Use the same OpenAI-style payload. Just send requests through TokenGuard's proxy endpoint.

Designed for SaaS teams

Built for founders, agencies, and developers running multiple AI products with real API costs.

Why not just use OpenAI directly?

What you gain with TokenGuard.

What founders are saying

Built for real AI products.

We were spending $800/month on OpenAI with zero visibility. TokenGuard gave us dashboards, budgets, and the confidence to keep shipping AI features.

Founder, B2B SaaS · 4 AI products

Client billing for AI usage was a spreadsheet nightmare. Now every client has their own key and budget. I literally saved a day per month.

Founder, Marketing AI Agency · 11 clients

Set up in 15 minutes. One env var change in our Next.js app and we had instant spend tracking. Would not ship an AI feature without it now.

FAQ

Frequently asked questions.

What is TokenGuard?+

TokenGuard is a transparent proxy and dashboard that sits between your app and the OpenAI API. It enforces spend budgets, issues per-project API keys, logs every request, and gives you a real-time dashboard of where your AI cost goes.

Do I need to change my OpenAI payloads?+

No. The proxy accepts the exact same JSON payload format as the OpenAI API. You only change the base URL and swap your OpenAI key for a TokenGuard key. One line change in most setups.

Does TokenGuard store my OpenAI key?+

If you choose to store a per-project OpenAI key, it is encrypted at rest with AES-256-GCM before being written to the database. The raw key is never logged or returned by the API.

What happens when a budget limit is reached?+

TokenGuard returns HTTP 429 to your app. If you have configured a fallback model, it will route to that model instead of blocking. You can set both daily and monthly limits independently.

Can I use it for multiple SaaS apps?+

Yes. You can create one project per app, client, environment, or team. Each project gets its own key, budgets, and dashboard. The Pro plan supports 20 projects and Agency supports unlimited.

Does it support Stripe billing?+

Yes. TokenGuard ships with a full Stripe integration for Starter, Pro, and Agency plans. Checkout, upgrade, downgrade, and the customer portal are all built in and configurable with your own Stripe keys.

Is it production ready?+

TokenGuard is designed for production use. It uses bcrypt-hashed API keys, encrypted provider credentials, JWT auth, rate limiting, and proper error handling. A /dashboard/deployment page gives you a live health checklist before you go live.
