    I’m excited to share ToolJet 3.0, a major update to our open-core low-code platform for building internal tools.

The initial post hit #1 on HN, bringing in a wave of…

    Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it. Today, we’re excited to get HN’s thoughts on one of our new products: Retool Mobile. It lets you build and deploy mobile apps in minutes, not days. The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…

    Hi HN, founder here again! I first launched ToolJet here in 2021 as a one-person project. It blew up really well & got 1k stars on GitHub (https://github.com/ToolJet/ToolJet/) in around 8 hours. Back then ToolJet was basically a frontend builder that could connect to different data sources. Since then, we kept expanding: - Added a workflow automation tool so builders could orchestrate background jobs. - Added a built-in no-code database so builders didn’t need to spin up a new db. - Eventually grew into a full-stack platform for internal tools. - And other obvious…

    Hey HNs: This is Vincent from the ILLA team. I'm sure you guys see tons of "Open-source" and "Alternative to Retool" these days. I won't deny Retool is a great product, and so are many open-source competitors such as Appsmith, Budibase, Tooljet etc. However, what makes ILLA so special? What advantages does ILLA have that allow users to choose ILLA instead of others? Well, I would like to answer those questions to all folks at HN one by one. First, we are similar to Retool, or Appsmith but we have many different our own features. We are a true open-source project all the folks here can check…

    Hi, founders! We’ve actually launched quite some time ago, but (semi)pivoted a few times along the way. Jet Admin is an app builder for creating internal tools, admin panels, dashboards, external portals, and so on without coding. You can connect to any backend, assemble a UI through the visual builder, and set up data binding, transformations, conditionals, etc. through the point-and-click interface. If you need to, you can create custom HTTP, SQL queries, make data transformations with JS, and embed custom UI components. We believe that product, data, operations teams should be able to…

    Hi there, Mike here from Budibase. We’ve recently launched AI Agents into Beta, alongside our existing open-source app-building and automation tools. We built Budibase Agents for teams that want to leverage AI within real-world workflows, using their own LLMs, data, and APIs. Because of this, our Agents can be powered by any LLM with an OpenAI-compatible API, including open-source and locally-hosted models. This means you can build Agents that connect to your existing toolstack, within your own environment. Some more details: - Agents' behavior is configured using natural language…
