Retool Alternatives (2026): 10 Tools Compared

Retool is a popular choice for turning databases and APIs into internal tools, but it's built with developers in mind and it isn't the only route. Perhaps you want something simpler for a non-technical team, an open source option you can host yourself, or a builder that starts from a spreadsheet you already have.

Here are ten Retool alternatives in no particular order, sorted alphabetically. I've mixed smaller, newer builders with a few well-known names, and every description comes from each tool's own website and directory listings rather than guesswork. If your main aim is a clear overview of your numbers, my marketing dashboard template shows what to put on one screen.

Retool alternatives side by side

In the free plan column, Yes means the tool's own site lists a free plan, a free developer plan or free open source software. Trial only means there's a free trial but no ongoing free tier. Free versions usually come with limits on users, apps or support, so check what's included on the tool's own site.

Tool	Type	Good for	Free plan
Appsmith	Open source app builder	Admin panels on top of your own databases	Yes
Bubble	No-code app builder	Building full web and mobile apps without code	Yes
Budibase	Open source app builder	Internal apps and automations you can self-host	Yes
Glide	Spreadsheet-to-app builder	Turning existing sheets into simple business apps	Yes
Microsoft Power Apps	Low-code platform	Apps that connect to Microsoft 365 tools	Yes
Noloco	Portal builder	Client and team portals on top of existing data	Yes
Softr	AI app builder	Client portals, trackers and intranets	Yes
Superblocks	Internal app platform	Governed internal apps for larger teams	Trial only
ToolJet	Open source app builder	Internal tools with AI help and self-hosting	Yes
UI Bakery	Low-code builder	Admin panels and dashboards on your own data	Yes

What to look for in an internal tool builder

An internal tool is simply software for your own team: an admin screen, an approvals form, a client portal or a dashboard. Most builders can make one, so the differences come down to who'll be building and maintaining it.

• Who builds it. Some builders expect a developer who's happy with code, while others are designed for an operations manager who has never written a line.
• Where your data lives. Check which databases, spreadsheets and business apps the builder connects to, because the tool is only as useful as the information it can reach.
• Hosting choice. Some can be installed on your own server, some run only in the maker's cloud, and some offer both. Think about where your customer details need to stay.
• Users and permissions. Decide who can view, edit or approve, and whether clients or contractors need their own limited access.
• Customisation. Ask what happens when you need something the visual builder doesn't offer, such as custom code or a connection to an unusual system.
• Looking after it. Every internal tool needs updating when your processes change, so choose something the person who'll maintain it feels confident using.

Questions to ask before you build an internal tool

• What job should the tool do, and how does the team handle it today?
• Where does the information live now, and who updates it?
• Do clients or partners need to log in, or is this for staff only?
• Is there a developer on the team, or will a non-technical person own it?
• Would a simpler fix, such as a shared spreadsheet or an automation, solve the problem first?
• What happens to my data and my apps if I decide to leave this builder?

Which type of internal tool builder suits your business

• Developer-friendly builders suit teams with technical staff who want to connect databases, write queries and keep control of the code.
• Open source builders suit businesses that want to host the software themselves and avoid being tied to one vendor.
• Spreadsheet-to-app builders suit small teams who already run on sheets and just want a friendlier front end.
• Portal builders suit agencies and service businesses that want clients to log in and see their own information.
• Platform suites suit larger organisations that already standardise on one vendor's tools and want apps to fit in with them.

If you're deciding between building an app and automating the steps behind the scenes, my comparison of workflow automation tools may help, and my notes on dashboards for marketers show how a simple view of your data can go a long way.

Moving your internal apps to a different builder

• List every app and screen your team uses, and note who relies on each one.
• Start with one small internal tool rather than your most important process.
• Check how data is stored and whether you can export it before you build anything.
• Run the new version alongside the old one for a short overlap, and ask users what's missing.
• Write down how each tool works, so the knowledge doesn't live in one person's head.
• Tidy up permissions as you go, removing access for people who've left or changed role.

Internal tool mistakes worth avoiding

• Building a complicated tool before you've written down the process it should follow.
• Giving everyone full access because it's quicker than setting up roles.
• Choosing a builder only because the demo looked impressive, without testing it on your own data.
• Leaving one person as the only one who understands how the tool works.
• Forgetting that a tool wired to live data can change records, so test on a copy first.

The case for newer, independent internal tool builders

Smaller builders often concentrate on one kind of user, whether that's a developer wanting speed, a team that works mostly in spreadsheets, or a business that needs client portals. That focus can mean simpler setup and friendlier support than a big platform designed to do everything.

Before you commit, check the builder is still being updated, that you can export your data and apps, and that its free plan or trial terms are clear on its own site. Try it on a small, real job first.

Do you make an internal tool builder or low-code platform? Tool makers can ask to be considered for a featured place on this list.

Picking your Retool replacement

Shortlist two builders that fit who'll be building and where your data lives. Build the same small tool in each, such as a request tracker or a simple admin screen, and keep whichever one your team finds easiest to use and maintain.

Frequently asked questions

What is the closest thing to Retool?

Developer-friendly internal tool builders that connect to databases and APIs and let you add code are the closest match. Open source builders you can host yourself are a good place to start looking.

Is there a free alternative to Retool?

Yes. Several builders on this page list a free plan, a free developer plan or free open source software. The limits vary, so check what each tool's own site includes.

Can non-developers build internal tools?

Yes. Some builders are designed for operations teams and start from a spreadsheet or a plain-English description. Anything complex may still need a developer's help.

Should I self-host an internal tool builder?

It can help if you need your data to stay on your own servers, but you'll need someone to install, secure and update it. A hosted version removes that work.

What can I build with an internal tool builder?

Common examples are admin panels, request and approval forms, client portals, inventory trackers and dashboards that pull from your existing databases and spreadsheets.
