Experience LLM trading made easy
In the app: connect providers and keys, tune prompts and model settings, pick a mode and cadence—then context in, checks on, orders to the venue you linked for that model.
Intuitive trading workspace
Dense operators layout: balances, model output, connection status, and alerts without tab overload.
Your exchange, per model
Link one venue per model for execution. Add more exchange accounts when your plan allows—not smart routing across venues.
Secure & transparent
Encrypted keys, saved runs you can reopen, and tight access patterns you control.
Effortless usability
Remote config, presets, and safe rollouts so PMs and engineers share one surface.
Balances on your venue
See balances and status for the exchange linked to each model—not a multi-venue risk desk.
Room to grow
Add more models and exchange connections as your plan allows—each model still executes on one linked exchange at a time.
Go live in three steps
Connect
Add LLM providers and exchange API keys (test before save). Sign in with Firebase.
Orchestrate
Set schedules and prompts. Each run validates the model’s plan before any order is built.
Run & monitor
Sim, paper, then live on one linked exchange. The scheduler runs on your interval—no mandatory human sign-off before each run. Check PnL and saved decisions in the app when you want.
Pricing made simple
Pick the plan that fits your trading volume and team.

Frequently Asked Questions
Everything you need to know about FE!N
Is my API key secure?
Yes. Keys are encrypted (AES-256-GCM) and never stored in plain text. We only decrypt them to call APIs, and you can remove them anytime. For exchange keys, use trade-only keys with no withdrawal if your exchange offers that. If your key can withdraw, FE!N cannot change that—only your exchange can.
What if my LLM makes a bad trade?
Before an order sends, FE!N checks the symbol, size, and type. Practice, test money, and live are separate so you can learn safely. We also save what the model chose and what traded so you can look back and refine your approach over time.
Can I try simulation or paper before live?
Yes. Shipped modes are simulation, paper, and live—use them in that order as your confidence grows. There is no built-in historical backtest or long-range replay product yet (roadmap). FE!N does not compile a plain-English paragraph into a production bot; you connect providers and keys, configure prompts and model settings, choose the mode, and schedule runs. Switch modes when your workspace allows.
Which LLM providers are supported?
FE!N supports all major LLM providers including OpenAI (GPT-4, GPT-3.5), Anthropic (Claude), Google (Gemini), DeepSeek, Mistral, Llama, and more. You can also use any LLM with a REST API. See our full catalog at the bottom of the pricing section.
What exchanges are supported?
We support several exchanges. Each model uses one linked exchange at a time. You can add more accounts on some plans, but we do not split orders across exchanges. Ask us for the current list.
How does pricing work?
You can start free. Paid options include Hobby (~$9), Starter ($24), and Pro ($79). Names, prices, and limits in Stripe and the app are the ones that count. Trials apply where we turn them on.
