Who can you trust?

Can you trust Agentic AI for real-world business process orchestration?

Everywhere you look, someone is selling “Agentic AI.” Demos are dazzling. But when it’s time to let an AI do things in your business (take a payment, reschedule an appointment, update an order, open a ticket), reality bites.

Can your SMB team wire real tools without hiring an AI consultancy for thousands of dollars?

Can you trust an AI not to mix up arguments or invent parameters?

Can you deploy it everywhere customers are (Web/SMS/WhatsApp/Phone) and sleep well at night?

These are the tough questions that led us to develop JSFE. Our open-source JavaScript Flow Engine (JSFE) was built because the only answer that matters is trust, especially when granting AI access to your workflows and systems, and more so in customer-facing, real-time channels.

What is JSFE?

A tiny, host-agnostic engine that can turn any conversational system into deterministic workflows:

• Flows you can easily define and test: steps like SAY, SAY-GET, CALL-TOOL, SET, CASE, SWITCH make control explicit, declarative, deterministic, and testable.
• Tools you control: HTTP or local functions with strict JSON-Schema params, flexible response mapping, retries, timeouts, and rate limits.
• Session isolation & auditing: each conversation stays sandboxed. The host sees step-by-step state during the session for complete observability. JSFE itself doesn’t store any data, but allows your app to persist it, otherwise it’s dropped when the session ends.
• AI-optional: plug any model (OpenAI, Bedrock, Gemini, Groq), or skip AI and trigger flows directly for kiosk/IVR use cases.
• Host- and channel-agnostic: run the engine in any JavaScript host to orchestrate precisely controlled flows on web chat, SMS, WhatsApp, or Phone.
• Voice-specific integration: convert free-form voice input into context-aware, sanitized inputs.

JSFE is open source — inspect it, run it locally, integrate it into your cloud backend, in the browser, or your on-site Node. Meaningful trust requires transparency.

Design, test, and ship safely

Each business flow can be designed and tested independently as a self-contained script, following the same structure we use in our demos and tests (e.g., make-payment.js). Iterate locally until the workflow passes its checks, then copy/paste the generated .flows and .tools files into your choice host (or your instantAIguru configuration). The exact definitions you tested are the ones you deploy across Web/SMS/WhatsApp/Phone, giving you production confidence without surprise behavior.

Safety you can validate

Agentic buzzwords won’t reconcile refunds or collect money at 2am — but deterministic orchestration will. With JSFE, you decide what’s allowed, how it’s called, and what happens on failure. You and your team own the flows. Your tools stay behind strict contracts. The AI can suggest, but it can’t wander.

Field tested

Curacao Department Stores entrusted our engine to handle customer credit payments, integrate with CRM, and support customers over App, Web, SMS and Phone, at scale. That’s what validated trust looks like in the real world: auditable steps, validated inputs, and repeatable outcomes.

How JSFE prevents “AI oops”

• Declared only: execution is limited to your approved tool registry.
• Schema-checked: every call is validated against JSON Schema.
• Deterministic flows: Conditional logic that uses plain JavaScript expressions you can unit-test.
• Host-controlled auditing: step-by-step traces are visible to your app during the session.
• Proven Gain: hallucinations can’t change what actually executes.
