The Most Advanced Embedded Web Server
The Ioto agent contains our most advanced embedded web server and is perfect for serving local device management apps. It is blazing fast and extremely compact.
Ioto ® Local Device Management
Ioto incorporates everything we've learned over 20 years developing embedded devices. It is our most advanced embedded web server and is perfect for creating web management applications (especially single-page-apps). Ioto uses fiber coroutines so you don't have to struggle with multi-threaded programming or callback-hell. Ioto includes a HTTP web server, HTTP client, embedded database and JSON parsing in under 200K code.

Action Routines
Direct binding of URL requests to C functions
- Configurable routing of requests by URL patterns.
- Bind action routines (C functions) to URL paths.
- Request body, forms and query parameters are pre-processed for easy access.
- User role is authenticated before granting access to action routine.
- Stream request and response body for large data transfers.
- HTML helpers for encoding, decoding and escaping.
- Integrated support for file upload and post-processing by action routines.
HTTP Client
Connect to external services and data sources.
- Transfer chunk encoding and subscribe MQTT messaging client.
- Modelled on Browser Fetch API.
- SSL/TLS encryption.
- Full support for HTTP method verbs.
- Stream request and response body for large data transfers.
- Parallelism via fiber coroutines. No ugly callbacks or complex threads.
- Convenience support for JSON request and response bodies.
- Easily set request headers and access response headers.
- Tiny footprint: HTTP client component is 6K.
Embedded Database
High performance, in-memory document database.
- JSON document items with flexible query API.
- Fast in-memory red/black binary search indexes.
- Database schema to define and validate data items.
- Controllable journal-based persistency and change triggers.
- Efficient import and export of database items.
- Based on AWS DynamoDB OneTable.
- Simple, non-blocking API.
MQTT Client
Connect to the external services via MQTT.
- Publish and subscribe MQTT messaging client.
- MQTT 3.1.1 compliant.
- SSL/TLS encryption with ALPN over port 443.
- Supports connect, publish, subscribe, ping and disconnect messages.
- Message quality of service for reliable delivery.
- Retained message support.
- Parallelism via fiber coroutines. No ugly callbacks or complex threads.
- Elegant, non-blocking procedural API.
- Tiny footprint: MQTT component is 8K.
Fiber Coroutines
Parallelism without complext threads or the complexity of callbacks
- Support straight-line non-blocking code patterns.
- Network routines are fiber aware for automatic yielding while waiting for I/O.
- Ioto services are fiber aware including: HTTP server, HTTP client and MQTT client.
- Extremely fast fiber creation.
- Sandbox limits on fiber count.
- Low level fiber API to explicitly yield, resume and spawn fibers.
Safe Runtime
Battle hardened runtime after extensive peer-review and fuzz stress testing.
- Portable, cross-platform O/S abstraction.
- Safe strings, lists, hashing and buffer management.
- Event and timer scheduling.
- Fiber coroutines for non-blocking procedural programming model.
- JSON parser and renderer.
- JSON query engine.
- Logging framework – filter by source and/or message type.
- Global memory error handler.
Kickstart Device Management
Accelerate your local device management application.
- VueJS single-page application sample to use as a base for your device management application.
- Flexible and intuitive UI/UX for device management
- Login and registration with user management
- Navigation for simple or complex devices
- Granular user access role control per page
- Dynamic display via data tables and graphical widgets
- Property editing of any device data
- Monitoring Dashboards
- Library of display widgets including: gauges, graphs and tables
- Efficient design and imposes little load on the device.
Developing an effective device UI can take much longer than you think. Most companies expend years of developer time creating their device UIs. Kickstart for Ioto is a sample device management application that can dramatically shorten your development cycle for creating a your local device management app.
