AI-native development
Ship faster. Modernize continuously. Stay in control.
Bob coordinates planning, coding and verification across the software lifecycle — so developers spend their time on the work that matters most.
IBM Bob is an AI coding agent and development partner for enterprises. It helps teams understand, plan, build, test, secure and modernize complex software wherever the code lives — from modern Java and JavaScript services to COBOL, RPG and mainframe applications.
Bob picks the right AI model for each task, checks for vulnerabilities as code is written, and can run as SaaS or inside your own, even air-gapped, environment. As an IBM Silver Business Partner, NetCreativeMind helps teams roll out Bob with the right governance and puts it to work on modernization, testing and integration projects.

Test & SecureGenerate tests and catch vulnerabilities early.
ModernizeRefactor, upgrade and migrate step by step.
Key Capabilities
Built for scale, security and governance — everything your teams need to develop with AI in production codebases.
Agentic Modes: Ask, Plan & Agent
Ask explains code without changing it, Plan works through architecture before anything is written, and Agent turns the plan into working, validated changes. Teams can build custom modes and approve every change before it lands.

How IBM Bob Works
From an idea or a ticket to a reviewed pull request — with a developer in control at every step.
Ask
Explore the codebase, understand dependencies and get unfamiliar code explained in plain language.
Plan
Agree a technical plan and architecture before a single line changes.
Implement
Agent mode makes the changes across files, using the best model for each task.
Validate & review
Tests, security checks and a clean pull request — ready for your team to approve.
Modernize without the big bang
Turn months of modernization into days
The difference between a risky rewrite project and continuous, measurable progress.
Without an AI partner
Manual development
Weeks spent just understanding undocumented legacy code
Modernization as a high-risk, multi-year rewrite
Tests written last — or not at all
Vulnerabilities found after release
Unpredictable AI tool costs with no oversight

Our IBM Bob Services
From the first pilot team to enterprise-wide adoption, our IBM specialists help you put agentic development to work safely.
IBM Bob is an AI coding agent and development partner for enterprises. It understands your codebase and helps teams plan, build, test, secure and modernize software across the full development lifecycle.
How is it different from code completion tools?
Code completion suggests the next line. Bob works at the level of whole tasks — it can explain a system, agree a plan with you, make changes across many files, regenerate tests and check security, all with developer approval before code changes.
Can Bob work on legacy and mainframe code?
Yes. Bob handles languages such as Java, COBOL and RPG, and premium packages add specialised workflows for Java, IBM i and IBM Z modernization.
Can Bob run inside our own environment?
Yes. Bob is available as IBM-managed SaaS or self-hosted in environments you control, including air-gapped setups, with local or private model options for sensitive code.
How are AI costs controlled?
Bob routes each task to the most suitable model and gives administrators central visibility of usage and spend. Enterprise plans add pooled usage, limits per team or user, and budget tracking.
How do we get started?
A free trial is available, and we recommend a short pilot on a real application. We help you choose the use case, set up governance and measure the results before scaling to more teams.
