Tools for building software you can rely on

< By developers, for developers >

Build, verify and deliver your software with confidence using Popili.

Tools that not only help you build software, but also automatically verify if it's correct.

Software quality or delivery speed? We deliver both.

Increase your speed & reduce your costs

Popili automatically find bugs early and helps you fix them fast. You can start building your software earlier, increase parallel development, make late changes reliably and fast, remove bottlenecks in testing, and operate on shorter, more predictable timescales.

Eliminate bugs & deliver quality

Our tools provide advanced formal verification and code generation, which are fully automated and integrated into a modern development environment. Our verification engine detects hard-to-find errors that can elude testing, allowing you to ship your products with confidence.

Designed for developers

We only build tools that developers love using. From providing instant, rich feedback, to superior debugging, every aspect of the user experience is geared towards ease, greater productivity, and ultimately better code. And if you love modern programming languages, you’ll love coding in Coco too!

Our product

Debug the modern way

Fed up with debugging your software using text-based prompts? Popili allows you to visualise any errors it finds, so that you can quickly find and fix the source of the problem. When ready, let Popili re-verify your changes to check whether your code is correct.
Ship it with confidence

Popili generates high-quality, readable code that easily integrates with your existing codebase. With our automatic verification system, you can be confident that the software will work correctly in production, and there will be fewer surprises during integration testing.
Building your software with Coco

With Popili, you can develop your software in Coco, a modern programming language designed specifically for building event-driven software. As well as fully integrating into Eclipse and VS Code, Popili is also available as command-line tools to ensure seamless integration with your build system and CI pipelines.
Find bugs fast

Event-driven software can suffer from a range of hard-to-find errors including race conditions, deadlocks or messages arriving out-of-order. Popili uses an advanced formal verification engine that automatically checks that your software contains no issues. You can even start finding errors before you’ve finished building your software.
