Just describe your idea. Codey writes the code, draws the wiring diagram, compiles it in the cloud, and uploads it straight to your board — all from one browser tab. No IDE, no driver hell, no setup.
Save snapshots or record clips directly to your computer.
Is the DVR web client perfect? No. The legacy plugin architecture is frustrating. But for the price of free (already included with your DVR), it remains the fastest way to check your cameras on a lunch break or provide law enforcement with footage remotely.
Control Pan-Tilt-Zoom cameras directly through the browser interface.
You should rarely have to stand in front of the physical DVR unit. The web client should give you full administrative access to change passwords, format hard drives, update firmware, reboot the system, and configure network settings. 4. Backup and Export Controls
The landscape of DVR web clients is diverse. It ranges from native manufacturer interfaces to advanced open-source replacements.
Only used for very old systems requiring ActiveX (use "IE Mode" in Microsoft Edge as a workaround).
The Ultimate Guide to DVR Web Clients: Remote Surveillance Without the Software Hassle
Because expose your security system to the internet, securing them is paramount.
Adjust Pan-Tilt-Zoom cameras directly through interface directional buttons.
A well-designed dvr web client operates on Windows, macOS, and Linux.
For those utilizing older security systems or looking to build a customized, modern solution, Agent DVR by iSpy is a popular cross-platform alternative. It replaces traditional local clients with a highly optimized, modern HTML5 web interface that runs locally and integrates with hundreds of camera models. 3. Blue Iris
Every Codey project comes with a real wiring diagram. Color-coded wires, labeled pins, and a complete connection table — exportable as PDF or printed straight from your browser.
Red for 5V, black for GND, signals in distinct colors — exactly how you'd draw it on paper, only neater.
Below every diagram you get a Wire From → To list with pin labels, so you can wire your circuit without guessing.
One click to download a printable PDF of the diagram — handy for workshops, classrooms or your own build log.
Codey ships with a library of common modules: OLED displays, DHT11/22, HC-SR04, servos, relays, MOSFETs, RGB LEDs and many more.
Codey works out of the box with the most popular development boards. Plug one in over USB, pick it from the dropdown, and start vibing.
The classic. ATmega328P @ 16 MHz, 14 digital I/O, 6 analog inputs. Perfect for beginners.
Compact ATmega328P board. Same brains as the UNO, breadboard-friendly form factor. dvr web client
54 digital I/O and 16 analog inputs. The go-to when one UNO simply isn't enough.
The popular WROOM-32 module. Dual-core 240 MHz, Wi-Fi + Bluetooth, 30 GPIO. Save snapshots or record clips directly to your computer
Beefy S3: 16 MB Flash, 8 MB PSRAM, native USB-CDC. Two USB ports — Codey knows which is which.
RISC-V single-core, ultra-low-power, USB-C and a built-in OLED. Tiny but very capable. The legacy plugin architecture is frustrating
More boards added regularly. Direct USB upload over Web Serial — no drivers, no Arduino IDE required.
If you love vibe coding with Cursor or Claude Code, you'll feel right at home in Codey. Same describe-it-and-it-builds flow — except Codey runs your code on a real Arduino or ESP32, not on a server.

Cursor and Claude Code are excellent general-purpose AI coding tools — we use them ourselves. They're just not made for blinking an LED on a microcontroller. Codey Online fills that gap. Cursor® is a trademark of Anysphere Inc.; Claude™ and Claude Code™ are trademarks of Anthropic PBC. Not affiliated with either company.
Start vibing for free. Upgrade for unlimited AI and pro power.
For students and hobbyists.
For makers and creators.
Codey Online is built by OTRONIC, a Netherlands-based electronics company. We're passionate about making hardware programming accessible to everyone — from primary-school kids to professional firmware engineers.
We saw too many beginners give up on the traditional Arduino IDE because of driver issues, missing libraries and cryptic C++ errors. Codey closes that gap with modern AI and Web Serial — so you can stay in the flow and just vibe your way to a finished project.
