Open-source internal tools aren't political. They're practical.
Internal tools are different from customer-facing SaaS. You're not chasing growth; you're solving an internal problem. Your team depends on this tool running tomorrow, next month, and next year.
With Retool, you're locked in: proprietary code, no exports, no source code access. If Retool goes down, your team stops. If you need a custom integration they don't support, you're stuck waiting for their roadmap.
With Appsmith, you own the code. Apache 2.0 license. Export your app anytime. If Opsily can't help, you host it yourself. If Appsmith doesn't have a feature you need, fork the repo and add it. Your tool survives because it's yours.
40.5K GitHub stars and 20.4K commits prove this isn't an abandoned hobby project. It's a real, active codebase trusted by teams at GSK, Block, and HeyJobs. You can read the entire source, audit it for security, and contribute improvements.
For internal tools, that control isn't theoretical. It's the difference between a tool you depend on and a tool that depends on a vendor's quarterly earnings.
