Vendor-Neutral Software Development
CoreLine builds software you own completely. Open standards, client-owned repositories, portable infrastructure, and full documentation. If you ever want to leave, you take everything with you - code, data, and infrastructure configuration. No exit fees, no proprietary frameworks, no lock-in.
Client-Owned Code
Your repositories from day one
Open-source stack, no proprietary layers
Full documentation and knowledge transfer
Portable Infrastructure
Infrastructure-as-code (Terraform, CDK)
Cloud-portable architecture
No proprietary deployment tooling
Transparent Process
Open backlog and sprint boards
Direct access to engineers
Build-Operate-Transfer option
Sound familiar?
Your current vendor built your product on their proprietary framework and you can't leave without a rewrite
You don't have access to your own source code repositories or deployment pipeline
Your agency charges 'maintenance fees' for infrastructure they control but you pay for
You want to bring development in-house eventually but your vendor hasn't structured the project for handoff
Every CoreLine engagement is structured for portability from day one. You own the code, the infrastructure, and the knowledge - whether you work with us for six months or six years.
We design on open standards and widely adopted frameworks. No proprietary abstractions, no custom deployment tools, no vendor-specific patterns. Your codebase can be maintained by any competent engineering team.
Repositories live in your GitHub or GitLab organization. Infrastructure runs in your AWS, GCP, or Azure account. CI/CD pipelines are configured in your environment. You have full admin access from sprint one.
Architecture decision records, runbooks, and onboarding documentation are maintained throughout the engagement. If you bring development in-house, we support structured handoff with pair programming and team ramp-up.
Delivered outcomes
Using solutions such as React Native, Flutter, AWS, and many others makes it possible for us to upgrade your product as much as possible and to achieve a thriving collaboration. Here you will find our guide through our most used technologies and case studies related to each one.
AWS offers the tools to build powerful, flexible, and scalable applications, from compute and storage to databases and content delivery.
Simply put, Flutter is Google’s cross-platform framework that lets you build mobile, web, desktop, and embedded apps, all from a single codebase.
React Native is Facebook’s cross-platform framework that combines the best of React with native platform features - perfect for new projects or enhancing existing ones.
Other technologies we use
Frequently asked questions
Yes. Repositories are created in your organization (GitHub, GitLab, Bitbucket) before development starts. You have full admin access. Every commit is in your version control. There is no 'code handover' at the end because you've had it the entire time.
We use widely adopted, well-documented open-source technologies: TypeScript, React, Next.js, Node.js, Python, Go, PostgreSQL, Redis, Terraform, and standard AWS/GCP services. No proprietary frameworks, no custom build tools, no vendor-specific abstractions.
Yes, and we actively support it. We maintain architecture decision records, technical documentation, and runbooks throughout the engagement. When you're ready to transition, we offer structured handoff with pair programming, knowledge transfer sessions, and new-hire ramp-up support.
Our infrastructure-as-code approach and cloud-portable architecture patterns make provider migration feasible. We don't use proprietary managed services that create cloud lock-in unless there's a clear cost or performance advantage - and we document the trade-off when we do.
Most agencies don't think about exit. We structure every engagement so you can walk away cleanly: your code, your infrastructure, your data, your documentation. No exit fees, no proprietary dependencies, no 'you need us to run it' situations.
