Internal Tool Builder

Best Internal Tool Builders (2026): 8 Options Compared

Eight internal tool builders compared for small and mid-size teams: Retool, Microsoft Power Apps, Floot, Airtable, Softr, Appsmith, ToolJet and Budibase, with what each does well, what to watch and prices from their own pricing pages.

Floot ·

Key Takeaways

  • Retool is the strongest all-round platform for teams with a technical builder. Deep data connectors and enterprise controls, priced per builder and per internal user, with SSO, SAML and self-hosting on Enterprise.
  • Power Apps is the natural pick for Microsoft 365 shops. It sits inside Microsoft’s identity and admin model. Premium is 20 dollars per user a month billed yearly.
  • Floot fits non-developers who want a complete custom app. Describe it in plain English and get a full-stack app with its own database and logins, with no per-seat pricing for the app’s users. It does not document SAML SSO or self-hosting.
  • Airtable and Softr suit data-first tools with light workflow. Fast to start for teams that think in tables. Check record limits and which tier holds permissions and SSO.
  • Appsmith, ToolJet and Budibase are the open-source routes. Each offers a free self-hosted edition, with SSO and audit features on paid or enterprise plans.

Internal tool builders let a team create the admin panels, request queues, approval flows and dashboards that run the business, without commissioning custom software. The category now spans developer-oriented low-code platforms, Microsoft’s Power Platform, spreadsheet-style databases with interfaces, portal builders, open-source options you can host yourself, and AI app builders that generate a full app from a description. This list compares eight of them for the reader we have in mind: an operations lead, team manager or IT generalist at a small or mid-size company. Prices and plan details come from each vendor’s own pricing page, checked on 11 November 2026. A disclosure: this site is published by Floot, which is one of the eight. We have tried to rank it where it genuinely fits and to state plainly where others are the better choice.

How we chose and ranked

We looked at tools a small or mid-size company could adopt without a dedicated engineering team, and weighed five things: how quickly a non-specialist can ship a working tool; how access control works (sign-in, roles, SSO, audit logs) and which tier it sits on; how the tool connects to your data; how pricing scales as more colleagues use the app; and whether you can get your data out. Every price and plan detail below comes from the vendor’s own pricing page or documentation. Where a page didn’t state something, we say so rather than guessing.

The ranking reflects fit for our reader, not overall quality. A platform lower on the list may be the best choice for your situation, and the “Best for” line tells you when.

1. Retool

Best for: teams with at least one technical builder who need to connect internal tools to existing databases and APIs, and companies that need enterprise controls.

What it does well

Retool is a mature low-code platform for internal apps, with workflows, agents and AI app generation alongside the drag-and-drop builder. Its integrations page names PostgreSQL, MySQL, MongoDB, Microsoft SQL Server, Oracle, DynamoDB, Snowflake, BigQuery and Redis, plus REST, GraphQL, OpenAPI and SOAP. The pricing page lists audit logs and rich permissions on Business, and SSO, SAML, SCIM, Git source control, granular roles and self-hosting (cloud, self-hosted or air-gapped) on Enterprise.

What to watch

Pricing is per builder and per internal user, so cost grows with headcount. Several features security teams ask for sit on Business or Enterprise. Getting the most from it usually means someone comfortable writing queries.

Price

Free for up to 5 users. Team: 10 dollars per builder and 5 dollars per internal user a month billed annually (12 and 7 monthly). Business: 50 dollars per builder and 15 dollars per internal user billed annually (65 and 18 monthly), with external users priced in bands. Enterprise: contact sales.

2. Microsoft Power Apps

Best for: organizations already standardized on Microsoft 365 and Entra ID, with IT staff who manage the Power Platform.

What it does well

Power Apps builds canvas and model-driven apps on Dataverse and Microsoft 365 data, governed through Microsoft’s admin centers. Power Automate adds approval flows, which Microsoft documents in several patterns (everyone must approve, first to respond, sequential). The pricing page lists agentic features and Microsoft 365 Copilot chat in apps on Premium.

What to watch

Licensing has layers. Microsoft says some Microsoft 365 licenses include limited Power Apps rights for scenarios using Microsoft 365 data and standard connectors, while premium connectors and standalone Dataverse apps need a premium licence. Microsoft also notes the per-app licence is no longer available to new customers through some channels from 2 January 2026. Read the licensing guide before you design.

Price

Premium: 20 dollars per user a month, paid yearly, or 12 dollars with a 2,000-seat minimum. A free Developer Plan is for building and testing, not production. Extra Dataverse database capacity is 40 dollars per GB a month.

3. Floot

Best for: operations leads and IT generalists without developers who want a complete custom internal app (requests, approvals, trackers, dashboards) and many occasional users. Floot publishes this site.

What it does well

Floot is an AI app builder. You describe the app in plain English, in Floot’s editor or from ChatGPT, Claude, Claude Code, Codex or Cursor through its MCP server, and it builds a full-stack web app: a React frontend, server endpoints and a per-app Postgres database, with a live preview. You can upload a CSV and ask it to import the data. Apps can be published internally so only invited people can open them, or have their own sign-up and login (email, Google, Microsoft) with roles. Apps can send and receive email, run scheduled jobs and background tasks, send web and phone push notifications, use Google and Microsoft integrations you connect, and call services that require an IP allowlist from a fixed outbound IP.

What to watch

Floot does not document SAML SSO, SCIM, a platform audit log or self-hosting, and claims no security certifications. If your policy requires those, Retool Enterprise or Power Apps is a better fit. It also isn’t a connector-first tool: connecting to an existing production database is a build task rather than a dropdown.

Price

Free to start: 100 building actions a day and a one-time 3 dollar hosting allowance. Pro: 25 dollars a month with 1,000 actions a day, 10 dollars of hosting included and 5,000 AI credits. Power: 100 dollars a month. Hosting beyond the included amount is metered. No per-seat pricing for the app’s users; the database can be downloaded on every plan.

4. Airtable

Best for: teams whose tool is mostly structured data (an asset list, a vendor tracker, a content calendar) with light workflow on top.

What it does well

Airtable combines a spreadsheet-like database with interfaces and automations. Airtable describes Omni as its AI builder that can create a base, workflows and custom interfaces and dashboards from raw data. Its pricing page says read-only collaborators, form submissions and share links are not charged.

What to watch

Airtable’s plan documentation lists records per base of 1,000 on Free, 50,000 on Team and 125,000 on Business, and automation runs per workspace of 100, 25,000 and 100,000 a month. Editors are billable, including interface collaborators with editor or commenter permissions on Team. The public pricing page doesn’t state which plan includes SAML SSO or audit logs, so ask sales if you need them.

Price

Free plan available. Team: 20 dollars per collaborator a month billed annually (24 monthly). Business: 45 dollars billed annually (54 monthly). Enterprise Scale: contact sales.

5. Softr

Best for: portals and simple internal apps on top of a database, especially for teams that want a polished front end quickly.

What it does well

Softr builds apps on its own databases or connected sources, with workflows, forms, an AI app builder and built-in AI agents. Its pricing page distinguishes Team users (sharing a builder’s business email domain) from Client users, which suits mixed internal and external portals. Pro adds granular permissions and Google sign-in for app users; Business adds 2FA, domain-restricted signup, an installable mobile app and push notifications.

What to watch

App users are capped per plan (for example 10 Team plus 50 Client users on Pro, with paid add-ons), and records are capped (50,000 on Basic, 500,000 on Pro, 1 million on Business). SSO with SAML or OpenID, SCIM and audit logs are on Enterprise.

Price

Free plan available. Basic: 19 dollars a month billed yearly or 25 monthly. Pro: 99 yearly or 119 monthly. Business: 329 yearly or 395 monthly. Enterprise: custom. Softr lists a 50% discount for non-profits and education.

6. Appsmith

Best for: teams that want an open-source internal tool builder with a clear upgrade path to a paid business tier.

What it does well

Appsmith offers an open-source Community edition you install yourself and a cloud Free plan for up to 5 users with Google SSO and three standard roles. Business adds custom roles and access controls and audit logs. Enterprise lists SAML and OIDC SSO with Okta, Auth0 and Active Directory, granular attribute-based permissions, and air-gapped or managed hosting as add-ons.

What to watch

Business is capped at 99 users, and Enterprise starts at 100 users. The pricing page doesn’t describe AI features on any plan. Building effectively assumes some comfort with queries and JavaScript.

Price

Free and open-source Community editions. Business: 15 dollars per user a month, billed monthly. Enterprise: 2,500 dollars a month for 100 users. A 15-day Business trial needs no credit card.

7. ToolJet

Best for: teams that want an open-source builder with AI app generation and the option to self-host, and are comfortable paying per builder.

What it does well

ToolJet’s pricing page lists AI app generation, query generation and UI generation on every plan, with AI credits per builder. Cloud and self-hosted editions both have free tiers. The Team plan adds Google, GitHub, OIDC, LDAP and SAML SSO and 14 days of audit logs; Enterprise has unlimited end users and audit logs.

What to watch

End users are capped on lower tiers (50 on Free, Basic and Pro; 100 on Team). SSO arrives only at Team, the highest self-serve tier. Prices are per builder.

Price

Free: 2 builders, 50 end users, 10 apps. Basic: 23 dollars per builder a month. Pro: 79 dollars per builder. Team: 199 dollars per builder billed yearly (249 monthly). Enterprise: custom. AI credit add-ons cost 1 dollar per 100 credits.

8. Budibase

Best for: organizations that want to self-host internal apps on their own infrastructure without per-user licence fees.

What it does well

Budibase’s Community edition is open source and self-hosted with unlimited users, apps, automations and agents, and standard SSO. Enterprise adds enforceable SSO, PKCE OIDC, SCIM, audit logs, air-gapped deployment and Budibase AI.

What to watch

Community is limited to one workspace and one day of automation log retention, and lacks audit logs. Self-hosting means your team runs and updates it. The Cloud plan’s entry price is higher than most others here.

Price

Community: free, self-hosted. Cloud: from 299 dollars a month with 2 creators and 20 end users included; extra creators 50 dollars and extra end users 5 dollars a month billed annually. Enterprise: custom.

Also worth a look

Glide builds apps from Google Sheets, Excel, Airtable or its own editor, and suits simple mobile-friendly tools for frontline staff. Check its pricing page for how many team members and published apps each plan includes.

How to choose

Work through these in order. The first hard requirement you hit usually narrows the list to two or three.

  • Does policy require SAML SSO, SCIM, audit logs or self-hosting? Shortlist the platforms and tiers that list them.
  • Are you a Microsoft 365 organization with Power Platform governance in place? Start with Power Apps.
  • Will a technical builder connect to several production databases? Retool, Appsmith or ToolJet.
  • Is the tool mostly a shared table with light workflow? Airtable or Softr.
  • Do you want a complete custom app built from a description, with many occasional users and no developer? An AI app builder such as Floot.
  • Model three-year cost at your expected headcount, not today’s.

Common mistakes when choosing

  • Choosing on the demo, then discovering SSO or audit logs sit on a tier you can’t afford.
  • Ignoring per-user pricing for occasional users, such as everyone who submits a request once a month.
  • Underestimating record and automation limits on spreadsheet-style tools.
  • Assuming self-hosting is free: someone has to run, patch and back it up.
  • Picking a developer-oriented platform with no developer to run it.
  • Not checking how to export data before committing.
