Agentic software development

IBM Bob AI Coding Agent

An AI development partner that understands your whole codebase — helping teams plan, build, test, secure and modernize complex software faster, with the control enterprises need.

  • Ask · Plan · Agent modes
  • Legacy modernization
  • Security built in
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.

  • 90%Faster delivery — a full Java uplift in about 3 days at Blue Pearl
  • 10xFaster documentation of a 20-year-old system at APIS IT
  • ~40%Lower AI compute spend by routing each task to the right model
  • 3 daysTo rebuild a Java 8 installer in C++ at Migrato — not weeks

One partner across the whole SDLC

From the first question about unfamiliar code to the final pull request, Bob keeps full context of your system at every stage.

  • UnderstandExplain and document even undocumented legacy code.
  • BuildPlan and implement features with architectural insight.
  • 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.

  • Ask
  • Plan
  • Agent
  • Custom modes

Application Modernization

Repo-wide refactors, dependency upgrades and framework migrations with full system awareness.

  • Java
  • IBM i
  • IBM Z

Security at Authoring Time

Real-time checks catch vulnerabilities in the IDE and during pull request review — not after release.

  • Guardrails
  • PR review

Testing & Quality Automation

Build test frameworks, generate coverage and keep tests aligned with CI as code changes.

  • Test generation
  • CI

AI Cost Control

Multi-model orchestration uses the right model for each job, with spend visible in Bobalytics.

How IBM Bob Works

From an idea or a ticket to a reviewed pull request — with a developer in control at every step.

  1. Ask

    Explore the codebase, understand dependencies and get unfamiliar code explained in plain language.

  2. Plan

    Agree a technical plan and architecture before a single line changes.

  3. Implement

    Agent mode makes the changes across files, using the best model for each task.

  4. 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

What is IBM Bob?

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.
