Windmill.dev

This looks more like pipedream.com for automation scripts than a tool builder.

Definitely recommend Windmill.dev!

Founder of https://interval.com here. We're somewhere in-between Retool and Windmill which was mentioned on this thread.

Like Windmill, Interval is heavily code-focused. Our model lets you define tools in your existing TypeScipt/JavaScript codebase.

Like Retool, you can use Interval to build complete internal dashboards that handle the "view stuff" side of things, not just the script/workflow "do stuff" pieces.

If you want to build traditional forms: https://airforms.com

Founder of Bracket, YCW22 (https://www.usebracket.com/) here. You can use us to set up internal tools in Airtable, G Sheets, or Notion using 1-way and 2-way syncs.

Hi, I'm the lead dev of Saltcorn (https://saltcorn.com), I built it around the relational data model and it may fit your use case. Some people are finding it useful!

I just watched all the videos of Saltcorn on Youtube - and amongst the tools I researched so far this was most impressive. About to use it for a few internal tools soon.

Tooljet IMO is the most promising of the open-source Retool competitors. It has a great UI, is easy to use, plugs into everything, and is super flexible. If you haven't checked out out lately, I highly recommend it.

Out of curiosity, have you tried Budibase? I'm the co-founder and would be interested to hear your feedback if you've tried it.

Another one I'm trying out is Grist. They have Python scripting for functions and their way of viewing multiple tables on one screen is helpful. So far I'm liking it, although it misses some things like prefiltered referential selection boxes, and I would like more entry validation for deployment to typical internal end users. They're also not great at marketing themselves.

I looked at Budibase but it doesn't offer self-referencing table relationships and the CSV import process doesn't seem to support updates as cleanly as Grist. And the interface seemed kind of sluggish to me.

You should try ILLA. It's also an open-source low-code platform, and it's very stable. We are developing new features and iterating very fast. Try ILLA and let me know if you experience any inconvenience, and we will put all the advice into our next version plan. (https://www.illa.cloud/)

when are you guys going to provide cloud service?

Cloud service will be up online by the end of this year! You can try to self-host first! (https://github.com/illa-family/illa-builder) Let me know if you have more questions!

I believe you should definitely check DronaHQ https://www.dronahq.com/ .

An ideal alternative to Retool. We offer an intuitive drag drop interface with 150+ pre-built UI components and you can also connect with any database of your choice and build admin panels, dashboards, or any kind of web and mobile apps. The best part is you can choose what suits you the best between user-based pricing or usage based pricing.
