ESPHome vs ToolJet
A side-by-side editorial comparison of ESPHome and ToolJet — release velocity, themes, recent moves, and the top alternatives to consider.
ESPHome vs ToolJet: at a glance
What is ESPHome?
ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4
ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.
What is ToolJet?
ToolJet's AI builder goes model-agnostic with a multi-model catalog and MCP server baked into the enterprise image.
ToolJet has shifted its core narrative from low-code app builder to AI-powered app builder. In the past two weeks alone: MCP server packaging bundled into the EE production image, a multi-model build system with a visual model picker and effort variants, and AI build notifications wired into the canvas. The beta branch (v3.21.x) is a steady feed of component-level improvements while the LTS branch (v3.20.x) is now absorbing the AI infrastructure.

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4
◆ Current state
ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.
◆ Where it's heading
ESPHome is expanding in two directions simultaneously: broader hardware support (ESP32-P4, BK72xx BLE, new platform components) and more robust runtime behavior (RAMAllocator pattern, use-after-free fixes, better BLE-WiFi coexistence). The template climate component is the most user-visible addition — it brings custom HVAC logic into ESPHome's declarative model, reducing the need for external Home Assistant automations. Audio stack (i2s, resampler, mixer) reliability is also a consistent focus.
◆ Prediction
The 2026.10.0 cycle will likely continue the RAMAllocator pattern across remaining allocating code paths and add more ESP32-P4-specific features. Audio (voice assistants, speakers) will stay a top area given the ongoing i2s reliability work.
ToolJet
7.5INFRA · APIS
ToolJet's AI builder goes model-agnostic with a multi-model catalog and MCP server baked into the enterprise image.
◆ Current state
ToolJet has shifted its core narrative from low-code app builder to AI-powered app builder. In the past two weeks alone: MCP server packaging bundled into the EE production image, a multi-model build system with a visual model picker and effort variants, and AI build notifications wired into the canvas. The beta branch (v3.21.x) is a steady feed of component-level improvements while the LTS branch (v3.20.x) is now absorbing the AI infrastructure.
◆ Where it's heading
ToolJet is building the infrastructure to make its AI builder run any model from any provider, not just OpenAI. The model catalog with effort variants (presumably mapping to cost/speed tradeoffs) and the bundled MCP server position ToolJet as a platform that AI agents can drive — not just a tool humans use to build apps. The Confluence marketplace integration points to continued enterprise integrations.
◆ Prediction
The MCP server now in the EE image will likely get documented API coverage in the next 2–3 releases, making ToolJet a programmable target for external AI agents. A new Basic plan suggests pricing restructuring; look for the AI builder features to be tiered behind higher plans.
