What is OctoPrint?

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

The 2.0 candidate line reaches rc5, still stabilising rather than adding. This cut is bug and regression fixes: config subcommand options being ignored, chamber defaults missing from the schema, a deprecated babel-polyfill dependency slowing the UI, discovery data re-exposed for third-party clients, and doubled Error events from the serial connector. The testing asks now explicitly cover the Moonraker and Bambu connectors, alongside the serial migration checks that have been in every candidate since rc2.

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.

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

◆ Current state

The 2.0 candidate line reaches rc5, still stabilising rather than adding. This cut is bug and regression fixes: config subcommand options being ignored, chamber defaults missing from the schema, a deprecated babel-polyfill dependency slowing the UI, discovery data re-exposed for third-party clients, and doubled Error events from the serial connector. The testing asks now explicitly cover the Moonraker and Bambu connectors, alongside the serial migration checks that have been in every candidate since rc2.

◆ Where it's heading

Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else — and the rc5 asks name Moonraker and Bambu connectors as installable things to try, not future plans. The candidates themselves are converging: rc5's fixes are regressions in work introduced by earlier candidates rather than new migration surface. The unexplained error states the maintainer keeps flagging remain the open item holding the line short of a final.

◆ Prediction

Expect further candidates until the disconnected-after-error reports resolve, since that is the one issue called out across multiple RCs. A 2.0.0 final should follow once the connector migration stops producing regressions, with the Moonraker and Bambu connectors shipping as separate installable plugins rather than in core.

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.
