Budibase future as Retool alternatives reshape low-code tooling

Budibase sits at 28,335 GitHub stars, trailing ToolJet and Appsmith by roughly 12,700 each. This gap is significant because the top two projects are effectively tied in attention, with a star difference of only 30 between them. Budibase’s positioning has shifted away from pure app building toward an "AI Workflow Toolkit," a pivot that changes how it competes against established open-source rivals. The platform now leads the set with 76 releases in the last 12 months, compared to 66 for ToolJet and 20 for Appsmith. This release frequency signals high development velocity, yet the core license remains a complex split structure that requires careful legal review before enterprise adoption.

A split license and AI-first roadmap

The GitHub API returns NOASSERTION for Budibase’s license, meaning the detector cannot match the file to a single SPDX identifier. A manual read of the LICENSE file reveals the core is GPLv3, while paid features in packages/pro operate under the Business Source License. Packages that ship inside generated apps use MPL-2.0, creating a source-available layer on top of the open-source foundation. For teams planning to modify the tool and offer it over a network, this distinction matters more than for purely internal deployments where legal teams still ask questions. Budibase raised $7M in Seed II funding led by SignalFire, bringing total capital to $9.25M, which supports its push into AI agents and automations.

The company repositioned its messaging around AI agents, chat, and workflow automation rather than traditional drag-and-drop app building. In 2025, Budibase stated that existing app-building capabilities would not disappear, keeping low-code screens and data tables intact for users who rely on them. New features include specialized agents that access only chosen data and APIs, orchestrated through a chat interface that surfaces dynamic forms and charts. Role-based access controls apply strictly, ensuring no agent can bypass permissions granted to human users. The platform supports various LLMs via LiteLLM, including open-source models like Mistral ministral-14b-2512 and Qwen qwen3-32b.

Practical fit and migration realities

For teams needing simple CRUD tools, Budibase remains a strong choice due to its built-in database and 40+ data connectors. However, pricing scales quickly once you add creators or end users, with paid plans kicking in after 20 active users on self-hosted instances. Users frequently flag mobile usability as a friction point, noting that the experience is significantly worse on mobile devices than on desktop. The per-creator math can feel like a tax on shipping multiple projects, especially when adding a second builder costs $60/month. If your team consists of non-technical builders, the learning curve is steeper than the marketing suggests, as the component model assumes comfort with developer concepts.

Retool’s catalog of native integrations is broader than any open-source alternative, and its AI query generation has no direct open-source match. Teams migrating off Retool should export each app as JSON but document every query separately first, since the query library does not export cleanly. Running both tools in parallel allows you to audit each internal tool before moving users over, reducing the risk of broken workflows. Self-hosting Budibase controls where the platform runs, but it does not turn the apps into standalone code that can run independently of that platform. Whether AI-native generation will eventually replace visual builders entirely remains an open question for the next few years.
