How Toss helped 6 departments and saved 10 frontend dev cycles using ToolJet

Toss is one of South Korea’s leading financial platforms, offering a wide range of digital financial services. To scale, Toss needed to avoid overloading its front-end teams.

As internal tooling demands across departments grew, building admin dashboards and back-office apps in React became inefficient. Toss looked for a low-code platform that enabled backend developers and cross-functional teams to create internal apps without slowing down the core product roadmap.

‍

Despite their engineering strength, Toss’s teams ran into recurring obstacles:

• Building admin panels often required scarce frontend engineering time
• Departments needed tools fast, but couldn’t wait on central dev queues
• React-based tooling slowed delivery for short-term but high-impact tasks
• The cost of using frontend resources for non-core apps was too high
• The high cost of alternatives like Retool made it challenging to scale internal tools affordably

‍

ToolJet offered Toss a quick, cost-effective way to build and maintain internal tools:

• Backend developers created UIs without writing frontend code
• Apps were built and deployed in days, not weeks
• Departments gained autonomy, reducing dependency on engineering spri

‍

ToolJet helped Toss rethink how internal apps are built and maintained across the company. Within months, they saw:

• 10 frontend devs' worth of effort saved, allowing product engineers to stay focused
• 300+ internal apps built, with 100+ in active use
• Zero design or frontend bottlenecks, speeding up app cycles
• Short-term apps were shipped in hours, not days
• 3 years of adoption, showing long-term fit and value
