As answered by people managing Codility and Evonx.
Evonx's answer:
Evonx is built around a simple idea: software should be easy to create and just as easy to keep evolving.
You can start with a prompt, choose a ready-made template, or connect an existing codebase. Evonx then plans the work, writes the code, runs it in a live preview, and delivers the changes as reviewable pull requests that you own.
What makes it different from many AI builders is that it is not limited to creating disposable prototypes. Evonx can work on real, existing software, understand its architecture, and continue developing it without forcing a rewrite.
It also includes AI-powered game creation. Users can describe a game in plain language or start from a game template and generate playable games, visual assets, characters, levels, and gameplay that can then be refined through conversation.
Evonx's answer:
Evonx is a good fit for people who want AI to do more than generate a quick demo.
You keep ownership of the code, changes can be reviewed before they reach production, and existing applications can continue to evolve inside their current architecture. Evonx works with standard technologies rather than locking the project into a proprietary runtime.
It is also useful for people starting from zero: describe the product you want, start from a template, or create a playable game from a simple prompt.
The main advantage is that the same platform supports the full lifecycle — starting a product, previewing it, improving it, working with an existing repository, and shipping changes back to code you control.
Evonx's answer:
Evonx is designed for both technical and non-technical builders.
Its primary audience includes founders and entrepreneurs who want to turn ideas into working products quickly, small businesses that need custom internal software, product teams that want to ship features faster, and developers or CTOs who need help maintaining and extending existing codebases.
It is also suitable for creators who want to build playable games without starting from an empty game engine or writing everything manually.
Non-technical users can describe what they want in plain language, while experienced developers can connect repositories, review the generated code, and keep full control over how changes are shipped.
Evonx's answer:
Evonx started from a frustration we kept seeing in software development: creating the first version of a product was becoming easier, but maintaining and evolving real software was still slow and expensive.
Businesses often have working applications that are difficult to change because the original developers are gone, the codebase has grown complicated, or every small improvement requires another development cycle.
We built Evonx to make software evolution conversational. Instead of turning every request into specifications, tickets, and hand-offs, users can describe the outcome they want. Evonx understands the codebase, plans the change, implements it, and produces a live preview before anything is shipped.
The same technology is also used for new products and games, allowing someone to go from a simple idea or template to working software and continue improving it over time.
Evonx is developed in Türkiye with the goal of building a globally competitive AI-native software development platform.
Evonx's answer:
Evonx is built around modern web, cloud, AI, and Git-based development workflows.
The platform works with standard application technologies and can understand and evolve codebases built with stacks such as React, Angular, Vue, Node.js, .NET, Java, PHP/Laravel, and Python.
Evonx also integrates with Git-based repositories and development workflows, using isolated preview environments, automated testing, and pull-request-based delivery.
For applications created through the platform, Evonx can work with technologies and services such as PostgreSQL, Supabase, Firebase, Stripe, GitHub, Shopify, OpenAI, and Anthropic depending on the requirements of the project.
Evonx's answer:
Evonx is currently used by independent founders, software teams, agencies, and businesses building or evolving their own applications. We do not publicly disclose customer names without permission.
