What Real Time Logic does
Real Time Logic LLC, founded in 2004 and headquartered in Dana Point, California, licenses compact, source-deliverable C/C++ software components to OEM engineering teams building connected devices. Its product stack is organized in layers: a foundational embedded web layer (Barracuda Embedded Web Server, Minnow Server for memory-constrained microcontrollers), an application and edge platform layer (Barracuda App Server with Lua, Mako Server, Xedge browser IDE, Xedge32 for ESP32, Intelligent Edge Controller), a security layer (SharkSSL TLS 1.3 stack, SharkTrust PKI and certificate service, RayCrypto, softTPM), and a connectivity layer (SharkMQTT, LMQTT, SMQ pub/sub, OPC UA, Modbus, WebSocket and HTTP clients). The technology is purpose-built for resource-constrained targets running RTOS, Linux, QNX, VxWorks, or Windows, integrating with microcontrollers, industrial HMIs, and edge gateways.
The company earns revenue primarily through one-time, royalty-free source code licensing of these components (with multi-year contract terms and quote-based pricing) and complementary industrial-edge consulting engagements covering architecture, prototyping, integration, and production hardening. Distribution combines direct, engineer-led sales with self-serve downloadable evaluation code, a regional direct office in South Korea, and a channel partnership with Embedded Tools GmbH in Germany.
The customer base spans industrial automation, building automation, aerospace, defense, and healthcare, with documented OEM design wins at Schneider Electric (Modicon M580 controller, Altivar Process drives), Honeywell (NetAXS, Comfortpoint, Temaline), and logo references including Boeing, Bosch, GE Healthcare, Hexagon, Ultra Electronics, Hensoldt, and Belden. Real Time Logic competes in the embedded web server, MQTT/TLS, and industrial-protocol markets against open-source stacks and larger platforms by leaning on more than two decades of field-tested, resource-constrained-device expertise and compliance-oriented positioning around IEC 62443 and the EU Cyber Resilience Act.

Real Time Logic product offering
Product offeringCore offering
Real Time Logic licenses compact C/C++ embedded OEM software components that OEMs integrate directly into their hardware products. Offerings include secure embedded web servers (Barracuda Embedded Web Server, Minnow Server, Barracuda App Server, Mako Server), browser-based IoT frameworks (Xedge, Xedge32, Intelligent Edge Controller), embedded TLS/security (SharkSSL, SharkTrust, RayCrypto, softTPM), and IoT/industrial connectivity stacks (SharkMQTT, SMQ, OPC UA, Modbus). Licenses are sold on a royalty-free source-code basis across RTOS, Linux, QNX, VxWorks, and Windows targets.
Product overview
Real Time Logic provides a comprehensive suite of embedded OEM software products organized as a layered architecture. The foundation includes the Barracuda Embedded Web Server (compact C library for RTOS devices) and Minnow Server (tiny server for memory-constrained microcontrollers). The application platform layer comprises the Barracuda App Server (programmable C/C++ application server with Lua support) and Mako Server (single-executable Lua server for HLOS platforms). Built on these, Xedge and Xedge32 provide browser-based IDE and IoT frameworks. Security is addressed through SharkSSL (embedded TLS stack), SharkTrust (automated PKI/certificate service), RayCrypto (crypto library), and softTPM (software TPM). Connectivity is enabled via SharkMQTT, LMQTT, SMQ (real-time pub/sub), OPC UA, and Modbus protocols. Additional utilities include PikeHTTP, WebSocket Client, SMTP Client, and WebDAV Server.

Real Time Logic competitors and assessment
Company assessmentDirect peers
- wolfSSL: wolfSSL provides an embedded TLS library (wolfSSL/wolfCrypt) optimized for RTOS, embedded Linux, and MCU targets — directly comparable to RTL's SharkSSL stack, with overlapping OEM customers in industrial and IoT device security.
- Cesanta Software (Mongoose): Cesanta's Mongoose is a compact embedded web server, MQTT client, and TLS library shipped as C source for OEMs — the closest direct competitor to RTL's Barracuda Embedded Web Server and SharkSSL, serving the same constrained-device developer market.
Broad incumbents
- NXP Semiconductors (MCUXpresso, Edge): NXP bundles MCUXpresso SDK, EdgeConnect, and secure connectivity software with its i.MX and LPC MCU families — competing with RTL at the silicon-software boundary for OEMs building connected industrial and IoT products.
