Retool

Platform for building custom internal applications

Overview

Retool is a platform that helps businesses build internal apps quickly. It connects to databases and APIs (like Postgres, REST, GraphQL, Firebase, and Google Sheets) and lets users assemble tools with drag-and-drop building blocks, adding SQL queries, POST requests, and data transformers without much coding. The software handles data fetching and UI, so developers can focus on the unique parts of their tools. Compared with competitors, Retool emphasizes internal tools, supports many data sources, and offers on-premises options, Git syncing, collaboration features, and enterprise plans. Its goal is to let organizations create, deploy, and scale custom internal applications with less time and effort, boosting productivity and reducing the load on development teams.

Retool launches first platform to govern AI-coded apps as 93% of C-suite fear vibe coding risks

Retool, a governed platform for AI development used by over 10,000 organisations, has launched the first platform enabling teams to build with any AI coding tool whilst automatically enforcing enterprise governance. The company also released a survey of 300 C-suite executives examining governance and generative AI in enterprises. The platform allows developers to build applications using various AI tools including Lovable, Replit, or Claude Code, then deploy directly to production with security, permissions and audit trails enforced automatically. This addresses growing concerns about "vibe-coded" applications reaching production without proper governance. Retool's survey found 93% of CTOs, CISOs and CIOs are concerned about vibe-coded tools in production, with 38% calling it a top operational risk. Only 8% described their organisation's governance as strong, whilst 59% couldn't confirm whether they'd experienced AI-caused production incidents.

Getting started in Retool's new app builder.

Getting started in Retool's new app builder. There's more software being built inside companies today than at any point in history - and the average quality is lower than ever before. LLMs have made it possible for anyone to generate a working app on localhost in minutes. But localhost isn't production. Most of these apps have no authentication, no data access controls, no audit trail, and no path to deployment that IT has blessed. The result is shadow IT, but faster, and at 100x the scale. How do you let people keep building with these tools - without creating ungoverned software at enterprise scale? Retool, Inc. has the answer. Today, Retool, Inc. is launching the new Retool: a platform where you can build software wherever you want: Claude Code, Codex, Replit, Lovable, or Retool's own editor - and ship it through a single, governed runtime that enforces authentication, permissions, and data governance automatically. The new Retool platform: * Run anything. Deploy any React app on Retool - whether it started as a prototype in Replit, a Lovable project, or a Claude Code session. On import, Retool maps the app's data connections to resources your team has already configured and secured. No rewrite required. * Governed by default. Every app on Retool inherits centralized authentication, role-based access controls, and data access policies - none of it lives in the app code. Every interaction with your data is auditable. Deploy on Retool Cloud, in your VPC, or fully on-prem. The governance layer is identical everywhere. * Built to operate. Most AI-generated apps get built and forgotten. Retool handles what comes after: versioning, release management, environment promotion, access changes, and monitoring. One place to manage every app, for its entire lifecycle. In the early 2020s, low-code and no-code platforms bet that the secret to building software faster was moving away from code. Retool, Inc. made that bet, too. And for a long time, it was the right one. Customers built and shipped real internal tools faster than they could have written everything from scratch. But AI changed the economics of building. Generating code - written by models that get better every month - is now the fastest way to build custom software, and it's accessible to a far wider group of people than low-code tooling ever was. When Retool, Inc. started Retool, its proprietary abstractions made building fast. But they also meant LLMs couldn't work in its platform fluently, engineers couldn't bring their own tools and workflows, and apps built elsewhere couldn't run on Retool's platform or inherit its centralized governance. When the best way to build changed, Retool, Inc. changed, too. Retool's new app builder is the fastest, most natural way to build internal software - without giving up the control, visibility, and trust teams need once an app connects to real business data. The new builder is optimized for prompt-first workflows, but it's also built on a new architecture: apps in Retool are now written in React on the frontend and TypeScript on the backend. That means the agent is building with the same languages and patterns modern software teams already use. The result is higher-quality app generation, more expressive and customizable UIs, real backend logic, and code your team can inspect, review, and improve. Nothing is trapped in a proprietary format that only exists inside Retool. Retool, Inc. has also opened up far more input styles than before. Drag in screenshots, PDFs, design files, or spreadsheets, and the agent works from the same references your team already uses. Builders can pull in every place where work has already happened and hand it to Retool to pick up the torch and carry the project forward. You can prompt against the whole app, or click into any individual part of the preview to scope a prompt to exactly that component. And when you want to get closer to what's actually been built, two modes sit alongside the prompt interface. The Code tab lets you inspect or directly edit the underlying React. Click on any element in the app preview and you're taken to the exact line that needs to change in the code tree, without hunting through hundreds of lines of AI-generated code. As AI-generated apps have become more common, it's gotten harder to know what an app is actually doing with your data - and this is where most builders leave you with the least visibility. Retool isn't just generating your frontend; Retool, Inc. is generating the backend, too. So instead of asking you to read query logic buried in a large codebase, Retool, Inc. kept this layer legible by design. In the new Data tab, every piece of logic interacting with your data sources is created as a function you can open and understand. For more complex functions with conditional logic, there's also a visual data graph: a diagram that maps the relationships between inputs and data sources, showing you how user actions and app logic translate into operations against your data. The surface area for how apps come into Retool has expanded significantly. Now, teams can deploy existing React apps directly on Retool's platform - everything from prototypes vibe-coded in Replit, Lovable, and v0 to a project from a local repo. On import, Retool maps the app's data connections back to resources your team has already defined and secured. Those resources already carry the right data access rules. The app also gets Retool's app-level permissions, so teams can control who can view, use, and manage it through the same role-based access controls they use everywhere else in Retool. Instead of asking - or expecting - every team to figure out hosting, authentication, permissions, secrets, auditability, and data access from scratch, Retool becomes a center of excellence you can apply programmatically to every app you deploy. A few weeks ago, Retool, Inc. launched Retool's MCP server so admins could manage their Retool environments programmatically - querying resources, inviting users, auditing access - from Claude Code, Cursor, or Codex. Now, Retool, Inc. is adding app building to that set of tools. You can build and edit Retool apps directly from the agent you're already working in, and the project context you have there comes with you instead of getting rebuilt on the other side. And, because Retool can host any existing React code, you can keep building in your favorite CodeGen tools and point them towards Retool when you're ready to ship. If you're going to let people build from anywhere (which Retool, Inc. think you should!), governance can't be something each app implements on its own. It has to be a single layer that sits below all of them. Every interaction with enterprise data goes through Retool's governance layer. Data access, permissions, approved resources, environments, and deployment rules are configured by the customer and enforced consistently, regardless of how the app was built. The security doesn't live in the AI-generated layer. It lives underneath it. Having permissions and security live inside an individual app works when there are a handful of apps and a handful of builders. But it breaks down when software is being created across teams, tools, and skill levels. When every team has its own path to production, technical leaders lose visibility. Retool creates a single governance checkpoint. This matters for the long tail of software maintenance, too. Most of a piece of software's life isn't the initial build - it's updates, access changes, debugging, monitoring, deprecating, and keeping the app aligned with how the business changes. Retool handles all of that in one place. The more people building software, the more critical it becomes to ensure every app is secure before it reaches production. With Retool, your team has ultimate flexibility in how you build - but you don't have to figure out deployment alone. Retool, Inc. has partnered with leading consultancies, system integrators, and agencies who had early access to the new app builder and completed hands-on enablement to help you ship with confidence: Artefact, BitHippie, BoldTech, GxP, Lingaro, Nymbl, Sabai System, SingleWave, Sixth Generation, StackDrop, Stradia Partners, TechRebels, and Paramint. Today's launch is about the best way to build and ship vibe-coded apps. But this is the beginning of what's next. As Retool, Inc. has come to expect, AI-assisted development is already quickly moving forward. Retool, Inc. is seeing agents that act on data, trigger workflows, and call systems without a human in the loop at every step. The governance problem only gets more urgent as AI gets more autonomous. The resources, permissions, and approved pathways you define in Retool now become the harness that makes more autonomous software safe to run. Retool, Inc. is excited to share more soon. The new app builder is available now for Retool Cloud customers. Self-hosted customers can access it in the Retool 4.x stable release. Try it today. New Enterprise plan customers who sign by September 30, 2026 get AI credits worth up to $10,000 annually.

Retool sessions at Data + AI Summit 2026.

Retool sessions at Data + AI Summit 2026. Last year, Retool, Inc. were honored to be named the 2025 Databricks Emerging Partner of the Year, in recognition of its shared commitment to help enterprises turn Databricks data into action. A lot has changed since then. The foundation making that possible keeps getting stronger. That's what has Retool, Inc. excited to be back at the Data + AI Summit this week, and to share what's next for its partnership. Across financial services, retail, consumer goods, healthcare, and manufacturing, the same question keeps coming up. You have the data, you have the models, so why is putting that insight to work still the hardest part? That gap between knowing and doing is where value gets lost. Closing it is exactly where Retool, Inc. is focusing its partnership, and as launch partners for Lakebase and Agent Bricks, Retool, Inc. is closer than ever. "The future of enterprise AI is grounded in trust and transparency. Retool has become a critical part of how Databricks customers put AI to work across their enterprise. By expanding our partnership to include Lakebase and Agent Bricks, we've unlocked new ways for teams to turn insight into action without sacrificing governance." - Shanku Niyogi, SVP of Product, Databricks In February, Databricks Lakebase became generally available: a fully managed Postgres database that lives inside the same platform where your analytical data already sits. Retool, Inc. is a launch partner because Retool, Inc.'d been building on it ourselves and believe this is where operational databases are headed. Separating storage from compute is the architecture that makes scale manageable and Databricks is leading the way. This foundation is already running in production across more than one million serverless Postgres databases inside Retool. Which is what made the Retool Lakebase connector possible. Now your operations teams can resolve service tickets, manage inventory, and process orders against the same data your analysts are already using - without provisioning anything. "The operational layer around AI is becoming just as important as the model layer. With the Retool Lakebase connector, our teams can respond to fleet and operations data in real time and scale without re-architecting our tools." - Agata Rother, Operations Systems and Insights Team Lead, Wayve Retool, Inc. is also a launch partner for Agent Bricks, Databricks' platform for building and governing enterprise AI agents grounded in your own data. New capabilities like Document Intelligence for unstructured data, Genie Agent Mode for multi-step reasoning, and Custom Agents give joint customers more ways to put AI to work on real business problems. The integration that has its customers most excited is its agent-to-agent connection with Genie Spaces. When Databricks surfaces a signal like a revenue anomaly, an inventory gap, or a support spike, your teams can act on it directly inside Retool without switching tools or rebuilding context. "We can now move from explanation to action without losing momentum. Agent-to-agent communication between Databricks Genie Spaces and Retool means the right people are responding to the right signals sooner, on governed enterprise data, and influencing high-stakes decisions." - Anthony Perez, VP of Innovation and Growth Programs, MiQ If you're at Summit this week, Retool, Inc. has three sessions worth catching: * The Last Mile of AI: How Reckitt Builds on Databricks A real-world look at how Reckitt is delivering consumer insights up to 60% faster * Customer Zero: How Retool Scaled to 1 Million Databases on Databricks Lakebase The architecture, governance decisions, and lessons from building on Lakebase at scale * Responding to Signals: High-Stakes Decisions with Databricks Genie See a live demo of its agent-to-agent integration with Genie Spaces The team is on the ground all week at Moscone. Stop by Booth #212 to see live demos and learn about the exciting new way Retool, Inc. is making enterprise vibe coding safe for everyone. light Reader

Nokod Security expands platform into Retool to secure citizen development apps and AI agents

Nokod Security has launched an integration for Retool, enabling security teams to monitor and govern internal apps, workflows and AI agents built on the platform. The integration provides automated discovery of Retool environments, identifying over-privileged users, public-facing apps and insecure configurations. The platform offers continuous discovery, risk prioritisation, data flow visibility and remediation guidance tailored for non-technical builders. According to Gartner's 2025 CIO survey, 42% of organisations have deployed low-code/no-code platforms, with another 38% planning deployment by 2027. CEO Yair Finzi said the expansion allows organisations to embrace citizen development whilst maintaining data integrity and compliance. The integration connects to Retool environments within minutes, addressing security blind spots created as business teams build applications outside traditional IT oversight.
