Preventing vendor lock-in: why building applications with IBM Bob is smarter than low-code/no-code
Low-code and no-code platforms promised speed: building applications without an army of developers. They often live up to that promise. But anyone who is a few years down the line discovers the price: your applications, your data, and your processes are locked into the platform of a single vendor. And that vendor suddenly raises prices, and not in small increments!
With AI-driven development environments like IBM Bob, that trade-off shifts. You build just as fast, but the result is plain, readable source code that is yours. In this blog, we explain where the lock-in in low-code lies and how to avoid it with Bob.
Where is the lock-in with low-code?
Lock-in is rarely found in a single contract clause. It lies in the way the low-code or no-code platform operates. What you build exists only within that environment.
Proprietary models instead of code. Your application is a configuration within the platform. Exporting does not yield working, maintainable code. Therefore, migrating applications is essentially impossible.
Runtime dependency. The app runs only on the vendor's runtime. If you stop using the platform, your application stops.
Licensing models that grow with you. Prices per user, per app, or per transaction rise successfully. Negotiating is difficult when leaving is not an option. And in recent years, prices have risen extremely rapidly.
Data and integrations in the platform. Data models, connectors, and workflows are platform-specific. Migrating means rebuilding.
Scarce knowledge. Developers learn the platform, not the underlying technology. That expertise is expensive and non-transferable.
The consequence: the supplier determines your roadmap, your costs, and your exit options. For organizations in the financial sector and the government, where exit strategies and continuity are mandatory, this is a serious risk.
What is IBM Bob?
IBM Bob is an AI-driven development partner for the entire software lifecycle. It is not a platform for building applications, but an assistant that writes, explains, tests, and modernizes code with your developers. Bob has been generally available since March 2026 ; multi-agent capabilities and modernization workflows were added in July 2026 .
Works in your own IDE and repository. Bob runs in the development environment and via Bob Shell on the command line and in CI/CD pipelines.
Agency-like. Bob deploys specialized agents and sub-agents for parallel, long-term tasks: from analysis and planning to implementation and review.
Literate coding. You describe what you want in plain language; Bob generates the corresponding implementation.
You remain in control. Bob works in modes where you approve proposals before anything changes in your source code.
Multiple models. Bob combines IBM Granite with models from Anthropic, Meta, and Mistral, among others.
Widely applicable. From Java and Python to COBOL, RPG, and SQL, with separate packages for Java modernization, IBM Z, and IBM i.
Why Bob prevents lock-in
The difference is fundamental: Bob is a tool, not a runtime. What Bob creates is ordinary source code in your repository. If you stop using Bob, your application continues to run.
You own the code. The result is Java, Python, TypeScript, or another standard language. Readable, version-controlled in Git, and maintainable by any developer.
Free choice of architecture and hosting. You choose your own frameworks, databases, and where to run: on-premises, Red Hat OpenShift, or any cloud. No mandatory runtime or license per user.
Open standards and integrations. You build connections using REST, OpenAPI, CMIS, or BPMN, not platform-specific connectors. This also makes your ECM and process environments interchangeable.
Knowledge that is transferable. Your team strengthens common development skills instead of platform certifications. Finding new people is easier.
Low-code speed, without the lock. Bob takes over the repetitive work: boilerplate, tests, documentation, and refactoring. A Java 11 codebase went to Java 25 in 3 days, compared to 30+ days the traditional way.
Also a way out of existing lock-in. Bob helps analyze, document, and rewrite existing Low-Code applications. This makes migrating from a low-code platform to custom code feasible within a short timeframe.
Let's be fair: Bob is also a product of a single vendor. But the dependency lies in your development process, not in your production applications. If you switch tools, everything you have built remains yours. To be maintained by you, or another vendor!
Low-code or Bob: how do you choose?
Low code is not inherently wrong. For a simple departmental app with a short lifespan, it can work perfectly well. For business-critical applications that last for years, ownership carries more weight.
Criterion | Low-code / no-code platform | Developing with IBM Bob |
Ownership | Application exists in the platform | Source code in your own repository |
Runtime | Mandatory supplier platform | Free to choose, any environment |
Costs in the long term | Growing with users and apps | Development tool per developer, no runtime license |
Exit strategy | Rebuild | Different tool, same code |
Customization and integration | Within the boundaries of the platform | Unlimited, via open standards |
Required knowledge | Platform specialists | Conventional development skills, enhanced by AI |
Suitable for | Fast, simple apps | Business-critical, long-running applications |

Novadoc is an IBM Gold Partner and specialist in IBM Business Automation, Enterprise Content Management, watsonx, and IBM Bob. We help organizations build applications that remain their own.
Lock-in scan: we map out how dependent your current applications are on your low-code platform and what an exit would cost.
Pilot with IBM Bob: we build or migrate a single application together, so you can see the difference in speed and ownership for yourself.
Integration with your ECM and process environment: we connect new applications to IBM FileNet, Business Automation Workflow, or other systems via open standards.
