Retool▲640
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,…

Illa – An open-source alternative to Retool▲151
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…

ToolJet – Build internal tools using AI▲8
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…

Open-source, self-hosted data management app and internal tool builder▲82
Hey HN, This is Adrian and David, and we're excited (and nervous) to show you basetool (https://basetool.io). Basetool helps companies view and manage all their data in one place. Companies have data in tons of places like BI tools, data warehouses, 3rd party services, and their databases. However, because the tools are not connected, it's a hassle to have visibility across the whole organization and even more difficult to safely share that data with the team or external collaborators. The vision is to give basetool access to your data source and get a tool that way above a…

No-code alternative to Retool, Appsmith, Internal, etc.▲123
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…

Plane - Open-source, self-hosted alternative to Jira▲18
Hi HN, I'm Vamsi, the founder of Plane(A simple, extensible, open source project and product management tool). Today, I’m here to share our journey with you all. It all started when we identified some of the most frustrating elements for teams when managing projects, especially with tools that force users to learn complex frameworks. We wanted to create something that was intuitive and easy to use. That's how Plane was born! We first open-sourced Plane back in November 2022, and the response was great. But it wasn't until we announced Plane on Reddit in April that we saw an incredible surge…

Srcbook – Self-hosted alternative to AI app builders▲67
Today we’re releasing a full AI app builder in Srcbook. We released our TypeScript notebook a few months ago (https://news.ycombinator.com/item?id=41291700) and the response was encouraging, but we kept hearing that people wanted to build interactive apps. Today we are releasing just that. You can think of it as an open-source and local version of vercel’s v0. We actually think of it as something in between an IDE and that, because we believe the code matters and don’t shy away from that: you can view and edit the code in a full editor, but prompt your way forward if that's…
