Stacker vs ToolJet: at a glance
What is Stacker?
Stacker's AI agent has absorbed every part of app building except the data itself.
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.
What is ToolJet?
ToolJet's latest tags are maintenance; the AI Builder features still wait on beta.
ToolJet ships near-daily on an LTS line for fixes and promoted features and a beta line for larger work. The newest LTS tag, v3.20.246, fixes uneditable rows in the 'Add new rows' popup and adds Tabs tests; the newest beta, v3.21.78, only adds security guideline docs. The substantive recent LTS changes were keyboard accessibility across widgets, a SCIM filter fix and v2 APIs for workspace user metadata.

Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.
◆ Where it's heading
The sequencing is deliberate: each release hands the agent one more thing that previously required the no-code editor, while the company repeatedly reassures users that the full editor still works on AI-built apps. That dual framing — build by conversation, refine by hand — is the position Stacker is defending, and it is a reasonable answer to pure prompt-to-app tools that leave nothing to adjust afterwards. The portal release is the notable widening, since it points the agent at the external-user product rather than internal tools.
◆ Prediction
Every surface except data connection has now been handed to the agent; connecting and mapping an external source — the step still done manually before any of this works — is the remaining gap, and the spreadsheet uploader is the first move toward closing it.
ToolJet
6.3INFRA · APIS
ToolJet's latest tags are maintenance; the AI Builder features still wait on beta.
◆ Current state
ToolJet ships near-daily on an LTS line for fixes and promoted features and a beta line for larger work. The newest LTS tag, v3.20.246, fixes uneditable rows in the 'Add new rows' popup and adds Tabs tests; the newest beta, v3.21.78, only adds security guideline docs. The substantive recent LTS changes were keyboard accessibility across widgets, a SCIM filter fix and v2 APIs for workspace user metadata.
◆ Where it's heading
Enterprise readiness remains the common thread: a v2 external API growing one resource at a time, identity-provider fixes and accessibility work. AI Builder attachments, GPT-6.1 Sol and tighter metered Cloud limits still sit on the beta line.
◆ Prediction
Expect AI Builder attachments, GPT-6.1 Sol and the new plan limits to reach an LTS tag, as AI Builder release 3 did. More v2 admin endpoints are likely along the way.
