ToolJet vs ESPHome
A side-by-side editorial comparison of ToolJet and ESPHome — release velocity, themes, recent moves, and the top alternatives to consider.
ToolJet vs ESPHome: at a glance
What is ToolJet?
ToolJet bundles MCP, multi-LLM switching, and PATs in a single beta — shifting from app builder to AI development platform
ToolJet v3.21.71-beta landed the platform's most consequential feature batch in recent memory: Personal Access Tokens, two-factor authentication, LLM provider switching with AI query transformation, MCP authentication via PATs, OneNote integration, CSV import into ToolJet DB, multi-model build support with a redesigned model picker, OTel observability on semantic conventions, and an AI-powered content generation option. The LTS branch ships more conservatively, receiving MCP bundling in the EE image and AI build cancellation support.
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.

ToolJet bundles MCP, multi-LLM switching, and PATs in a single beta — shifting from app builder to AI development platform
◆ Current state
ToolJet v3.21.71-beta landed the platform's most consequential feature batch in recent memory: Personal Access Tokens, two-factor authentication, LLM provider switching with AI query transformation, MCP authentication via PATs, OneNote integration, CSV import into ToolJet DB, multi-model build support with a redesigned model picker, OTel observability on semantic conventions, and an AI-powered content generation option. The LTS branch ships more conservatively, receiving MCP bundling in the EE image and AI build cancellation support.
◆ Where it's heading
ToolJet is repositioning from a low-code internal tool builder to an AI-native development platform. The MCP integration and multi-LLM provider switching indicate they're building for a world where AI agents are first-class citizens in app logic. The PAT + MCP combination creates a developer-facing API surface that third-party tools can call against ToolJet-managed apps, which is a meaningfully different product direction.
◆ Prediction
The beta's LLM-switching and MCP foundation will likely surface as a differentiated 'AI workflows' tier in a future pricing change, separating standard app-building from agentic AI features that consume LLM credits.
ESPHome

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.
