src/app.ts — ANTRX Client SDK
import { Antrx } from '@cipherlook/antrx';

// Initialize client runtime once with your tenant key
const antrx = await Antrx.init({ key: 'pk_live_your_key' });

// 1. Execute SQL queries on local OPFS database (0 server network traffic)
const orders = await antrx.sql.query('SELECT * FROM orders WHERE total > ?', [500]);

// 2. Compress heavy images on device before upload (reduced egress bandwidth)
const webpFile = await antrx.media.compress(rawImageFile, { quality: 0.85 });

// 3. Fallback policy: automatically falls back to cloud if device is low-spec
const summary = await antrx.ai.transcribe(audioBlob, { fallback: 'prefer-local' });

PRICING ARCHITECTURE

Pay per task. No seat fees. No idle cost.

Every module is billed by real client-side orchestration volume. You never pay for idle cloud servers, reserved VMs, or inactive users.

HOW IT'S BILLED
Strictly Task-Based
Each module has a transparent unit rate (per query, task, document, or audio minute). You pay strictly for operations your client applications orchestrate via the ANTRX SDK.
WHAT'S INCLUDED
Full Runtime & Tooling
Full SDK access, client-side module orchestration, automatic client updates, TypeScript definitions, and developer documentation with code samples.
WHAT'S NOT INCLUDED
Your Core Authority
Your central database authority, backend payment signing, and custom asset CDNs. These continue to run on your own infrastructure.
Representative FinOps Cost Example
Based on 100,000 active monthly users offloading document generation, database reads, and image preprocessing:
Workload Mix / Month Module Unit Rate Calculated Monthly Cost
1,000,000 Local SQL Queries (AntrxSQL) $0.00010 / query $100.00
50,000 Client Document Renders (AntrxDoc) $0.00045 / document $22.50
200,000 Client Image Compressions (AntrxMedia) $0.00030 / squeeze $60.00
Combined Monthly Total 1,250,000 Operations $182.50 / mo
* Representative task-based calculation. Real savings depend on your specific workload mix, concurrency, and client device fleet. Compare with traditional server clusters in our 30-Day Workload Audit.

COMPATIBILITY & RUNTIME

Device Support & Fallback Strategy

ANTRX adapts dynamically to each end-user device. If hardware is constrained or an API is unsupported, jobs route gracefully.

Device Tier Hardware Profile Execution Capability Fallback Behavior
High Tier Apple Silicon (M-Series), Intel i7/i9, Ryzen 7, Flagship Mobile Full WebGPU, Multi-Threaded WASM, Local Whisper AI Full on-device execution
Mid Tier Modern Core i3/i5, Chromebooks, Mid-range Android & iPhone OPFS SQLite, Document Renders, WebCodecs, Passkeys Local-first; heavy AI delegates if RAM is low
Low / Legacy Pre-2018 Devices, 2GB RAM budget hardware, Restricted WebViews Lightweight client crypto & session caching Automatically falls back to your cloud backend
Tested Browser Matrix
• Google Chrome: 109+ (Desktop & Android)
• Microsoft Edge: 109+ (Full WASM Threads)
• Apple Safari: 16.4+ (OPFS & WebCodecs supported)
• Mozilla Firefox: 115+ (ESR & Modern releases)
Flexible Fallback Policies
prefer-local: Attempts client execution first; delegates to cloud if hardware constraints are reached.
local-only: Enforces zero data transmission; errors if client execution is impossible (for confidential data).
server-only: Explicitly routes to cloud API for multi-gigabyte models or payment authority.
SECURITY ARCHITECTURE

Client-Side Security

Browser-enforced sandboxing, on-device encryption, and WebCrypto standards help protect user data.

SANDBOXED WORKERS
Process Isolation
Browser-enforced isolation designed for sensitive environments. Jobs execute in isolated worker threads with memory safety.
AES-256-GCM
On-Device Encryption
Data stored in local OPFS is encrypted with client-held keys via Web Crypto. Your servers never see plaintext payloads by default when zero-knowledge mode is used.
PASSKEYS / FIDO2
Hardware Biometrics
No passwords or shared secrets stored on your server. Hardware-bound WebAuthn private keys remain in user secure enclaves.
DEFENSE-IN-DEPTH
Server-Side Validation
Central server validates cryptographic proof of outputs before database commits. Never blindly trust client state.
Compliance Notice: ANTRX helps reduce your compliance surface by keeping raw PII on the user's device. Your DPDP and GDPR obligations still depend on how you deploy it. SOC 2: planned.
ARCHITECTURAL BOUNDARIES

When ANTRX is NOT the right fit

Client-side execution can cut infrastructure spend on suitable workloads, but it is not a silver bullet for every workload. We advise keeping these on your central servers:

1. Secrets & Tamper-Proof Logic
Payment processing, private API signing secrets, and entitlement checks must always remain on your backend authority.
2. Massive Multi-Gigabyte Models
Heavy 70B+ LLMs or multi-gigabyte training sets exceed client browser RAM limits and should run on central GPU clusters.
3. Legacy / Low-Spec Fleet Dominance
If your user base predominantly runs pre-2018 devices with single-core CPUs, heavy multi-threaded WASM should fall back to cloud.
* During our 30-Day Workload Pilot, our first deliverable is an honest workload-fit audit so you only move workloads where the numbers make sense.
FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

Everything engineering teams ask before deploying client-side workloads.

1. Which modules are production-ready? −
23 modules are categorized as Stable with frozen public APIs (SQL, IndexedDB storage, audio synthesis, compression, diffing, markdown, client telemetry, workers). Core modules like AntrxSQL, AntrxCompute, AntrxAuth, AntrxMedia, and AntrxRecord run in production inside CipherXOS. Other stable modules have been validated against standard browser test suites. 21 modules are in Beta with active developer APIs (Whisper AI, OCR, Vector Search, Digital Signatures, Bot Shield, Redaction). 10 modules in Advanced Runtime are Experimental research previews (AntrxVM, VPC, Erasure Sharding).
2. How is task-based pricing calculated and billed? +
Each module tracks client-side orchestration events (queries, tasks, documents, or audio minutes). You are billed only for actual operations orchestrated by the SDK. There are no monthly per-seat licenses, user count limits, or idle server charges.
3. What happens if a user's device or browser is low-end? +
The SDK inspects device cores and memory dynamically. Under the default prefer-local fallback policy, if a client device is low-spec or lacks required WebGPU/WASM extensions, jobs automatically route to your existing cloud APIs, so the feature keeps working smoothly.
4. Can users tamper with or reverse-engineer client-side code? +
Client code executes on user hardware, so any client-side code can theoretically be inspected by a determined developer. For this reason, private business secrets, payment authorization, and entitlement checks must always remain on your backend server.
5. What happens if a user clears their browser cache or site data? +
OPFS and IndexedDB are separate from the HTTP cache, so routine cache clears don't affect stored data. However, if a user explicitly selects "Clear All Site Data" in browser settings, all local storage is deleted. For critical data, ANTRX modules support periodic encrypted state diffs to your central backend.
6. How do we migrate away if we ever want to revert back to cloud APIs? +
ANTRX uses open web standards (W3C Web Workers, SQLite, WebCodecs, SubtleCrypto). Module inputs and outputs follow standard JavaScript Promises, ArrayBuffers, and Blobs, making it straightforward to redirect calls back to cloud endpoints with minimal refactoring.
7. How does the 30-Day Workload Pilot work? +
We start with an honest workload-fit audit. You select one candidate workload (e.g., PDF generation, client SQLite caching, or image compression). We help your engineers integrate the SDK in days and benchmark real cloud reduction side-by-side with zero upfront commitment.
