Key takeaways
- IBM Bob is a GA SaaS coding agent: desktop IDE plus Bob Shell CLI, with inference in IBM regions.
- Commands run on the developer machine. Remote hosted-agent execution was still a dated-free future item in the June 2026 V2 announcement.
- Individual plans are $20 / $60 / $200 per month for 50 / 180 / 1,000 Bobcoins; IBM i and Java packages are add-ons.
- IBM reports Granite plus Claude and Mistral routing. .bobignore is not a system sandbox.
FAQ
What is IBM Bob?
IBM's AI Development Partner: a VS Code-based desktop IDE and a Node CLI (Bob Shell) that plan, edit, and run commands against a local workspace, with IBM-hosted inference.
Is Bob Shell available?
Yes. IBM announced V2 in the IDE on June 24, 2026 with Shell following soon, then published a Bob Shell v2 release on August 5, 2026. Confirm the live changelog for your install.
How much does IBM Bob cost?
As of September 23, 2026, bob.ibm.com lists a 30-day trial with 50 Bobcoins, then Pro $20, Pro+ $60, and Ultra $200 per month. The IBM product page says the same amounts starting per instance. Enterprise is custom.
Does Bob run agents in IBM's cloud?
Inference is IBM SaaS. File and command execution are documented as local (or ACP-connected editor) processes. V2's remote-agent direction had no ship date.
Executive Summary
IBM Bob is IBM's generally available coding agent for enterprise SDLC work. The public product is a desktop Bob IDE and Bob Shell CLI. IBM's April 28, 2026 launch described a multi-model mix including IBM Granite, Anthropic Claude, and Mistral. V2 (June 24, 2026) documented a shared agent/harness with IDE-first rollout, subagents, approvals, and packaged modernization workflows.[1][2]
Checked September 23, 2026. bob.ibm.com prices a 30-day trial and three individual monthly tiers. The IBM product page repeats those dollar amounts as "starting at … per instance." Java and IBM i premium packages are listed as $20 and $40 per month; IBM Z is enterprise/annual. A first-month-free promo on Java and IBM i for new subscribers runs until December 31, 2026. Treat IBM's ~40% compute-spend and case-study speed claims as vendor-reported, not independently measured here.[3][4]
This page fills the IBM Bob gap in Foundation Lab Coding Agents. IBM develops Granite models, so Bob meets that report's lab-client criterion even though it also routes other labs' models.
| Attribute | Current evidence |
|---|---|
| Provider | IBM Software; product site bob.ibm.com.[4] |
| Execution | Local IDE/Shell processes; SaaS inference. V2 "further out" remote agents had no date.[2] |
| Interfaces | Desktop IDE, Bob Shell CLI, ACP into other editors (documented in V2-era product docs). |
| Entry tier | Free 30-day trial, 50 Bobcoins; Pro $20/month.[3] |
| Category | Foundation Lab Coding Agents |
Product Overview
Launch materials present Bob as moving enterprises from autocomplete to production-ready software, with watsonx Code Assistant customers described as having an adoption path rather than an immediate cutoff.[1] V2 folded earlier Code/Advanced/Orchestrator modes into Ask / Plan / Agent and described approvals for edits, commands, MCP, and skills unless auto-approve is on.[2]
A useful evaluation is a bounded Java or IBM i change with a compile/test command, not a toy prompt. Use Plan mode first, keep auto-approve off, and measure accepted diffs plus Bobcoin burn. No such workload was run for this profile.
Premium packages extend the same client for Java modernization, IBM i (RPG/COBOL/CL/SQL/DDS), and IBM Z. Those are add-ons, not the base agent.[4][3]
Technical Architecture
Public docs and the V2 announcement describe a three-tier split: agent reasoning, a harness (auth, flags, telemetry), and clients. Commands are child processes of Bob, not a documented OS/VM sandbox. .bobignore does not create system-level isolation. Workspace trust gates project-sourced config. Always-on HTTPS to bob.ibm.com and regional APIs is required; auth is documented as hitting US East even when conversation data is stored in another region.[2]
Bob Shell status: V2 said Shell would follow the IDE. IBM later published an August 5, 2026 Shell v2 post. Confirm changelog versions before asserting a specific 2.0.x build. Do not treat the June "further out" remote-execution paragraph as shipped.[2]
What Developers Say
Independent production write-ups were sparse in this pass. Practitioner roundups around the April 2026 launch mixed plan-mode praise with "VS Code wrapper" skepticism. A September 2026 Hacker News thread was mostly naming jokes. Those comments are not benchmarks, and this profile did not re-open every interview URL as a numbered source. No Bob workload was executed here.
Pricing & Licensing
| Plan | Price (bob.ibm.com, Sep 23, 2026) | Bobcoins |
|---|---|---|
| Trial | Free, 30 days | 50 |
| Pro | $20 / month | 50 |
| Pro+ | $60 / month | 180 |
| Ultra | $200 / month | 1,000 |
| Enterprise | Contact sales | Pooled |
Java Modernization $20/month; IBM i $40/month; IBM Z enterprise/annual. Prices are marked indicative and country-dependent. IBM's product page uses "per instance" wording for the same dollar figures. Bobcoins are a token abstraction; tokens-per-coin are not published on the pricing page.[3][4]
Licensing is IBM commercial SaaS, not an open-source client grant.
Competitive Positioning
| Alternative | Why compare |
|---|---|
| Claude Code | Often the coding-quality default in practitioner comments; Bob's pitch is IBM-stack governance and Z/i. |
| Tembo | Team operation of multiple harnesses in isolated environments. No IBM-documented Bob integration.[5] |
Disclosure: Ry Walker is Tembo's co-founder and CEO.
Assessment
Evaluate Bob if IBM i, Z, or governed Java modernization is the job and you accept local execution plus IBM SaaS inference. Do not buy it as a shipped remote-agent cloud runtime. Recheck Bobcoin burn on a real repository before standardizing seats.
