Paradev vs bb (2026): Agent Workspace vs the IDE That Builds Itself
Compare Paradev and bb for orchestrating AI coding agents. See how a full agent workspace differs from bb's self-extending, thread-based agentic IDE.
Paradev and bb both organize coding-agent work and support Git worktrees. Paradev centers task workspaces with terminals and patch review. bb centers live threads and extensible workflows. Both offer automation; compare the task lifecycle you need rather than treating a plugin architecture as missing functionality.
What is the bb IDE?
bb is an agentic IDE built around live threads and extensible plugins. Its official repository documents desktop, web, CLI, and API access. The desktop supports Apple Silicon Macs; its Linux AppImage is alpha, with other supported hosts using the documented launcher. Check those requirements before comparing it with Paradev on your machine.
This comparison is published by Paradev. We checked bb's official overview and installation requirements on September 23, 2026; this is not a hands-on speed benchmark.
Compare the workflow with one small task
Use the same repository commit, installed agent, model, and bounded task in both products. Record these observations before choosing:
| Step | Evidence to keep |
|---|---|
| Create a separate task | Working directory, branch, and worktree listing |
| Start and steer the agent | Exact prompt, any manual setup, and follow-up messages |
| Review the patch | Changed files, test command, exit status, and required corrections |
| Integrate the result | Merge result and checks on the combined branch |
Git worktrees separate working files; they do not sandbox processes or guarantee conflict-free merges. Use the parallel-task guide for the directory checks and review sequence.
At a Glance
| Paradev | bb | |
|---|---|---|
| What it does | Runs AI agents in parallel with Git worktree isolation, chat, review, and browser | Orchestrates coding agents in live threads you can follow, steer, or hand off |
| Category | Local-first agent workspace with remote hosts and cloud workspaces | Self-extending agentic IDE ("the IDE that builds itself") |
| Core unit | Workspace (worktree + terminals + review) | Thread (agent run in an environment, optionally a worktree) |
| Agent support | Any CLI agent (Claude Code, Codex, OpenCode, Cursor, Copilot, Gemini, Mistral Vibe, and more) | Claude Code, Codex, Cursor, Pi, OpenCode, Grok, omp, Hermes, plus any ACP agent |
| Isolation | Git worktree for new local branch-based workspaces | Optional Git worktree per environment |
| Surfaces | Desktop app, iPhone and iPad app, CLI, MCP server, TypeScript SDK | Desktop app, web app, CLI, HTTP API |
| Remote / cloud | Remote Access to machines you own, plus cloud workspaces | bb Connect tunnel + multi-machine enrollment |
| Automation | Scheduled agent sessions, TypeScript SDK, and MCP tools | Automations and extensible workflows |
| License | Source-available (ELv2) | Open source (MIT) |
What Is Paradev?
Paradev is a local-first desktop workspace for AI coding agents. It launches Claude Code, Codex, OpenCode, Cursor Agent, Copilot, Gemini CLI, Mistral Vibe, and other agent workflows inside isolated Git worktrees with persistent terminal sessions. Around that core, it adds a built-in diff/file editor, chat panel, in-app browser for docs and dev servers, port management, and MCP tooling. It also runs on machines you own through Remote Access and in the cloud through cloud workspaces, and it can schedule agent sessions as automations with a TypeScript SDK and a Slack bot. You can review inside Paradev or jump into VS Code, Cursor, Windsurf, JetBrains, or Zed. Source-available under Elastic License 2.0 (ELv2).
Paradev desktop supports macOS and experimental Linux; Windows is not available. Its iPhone and iPad app requires iOS 26 or iPadOS 26 or later, Pro, and either a reachable host or a cloud workspace. See platform and plan requirements and remote access setup.
What Is bb?
bb is an MIT-licensed agentic IDE built around threads and environments. Its product overview shows automations, browser previews, and review tools. Its repository documents desktop, web, CLI, and API access.
Key Differences
Built-in Workflows and Extensions
Paradev combines task workspaces, persistent terminals, diff review, a browser, and scheduled automations. bb also presents automations and previews in its product. To compare setup effort, start with a clean installation of each and record which steps your task needs, which features are already available, and which require configuration or extensions.
Threads vs Workspaces
bb organizes work around threads and environments; Paradev organizes it around workspaces. A new local branch-based Paradev workspace gets its own Git worktree, while cloud workspaces use clones and projectless sessions use scratch directories. See Paradev workspace types. In either product, verify the directory and branch before parallel writes instead of assuming every session has identical isolation.
Agents as Operators
bb exposes CLI and API access for operating the environment. Paradev exposes a CLI, MCP tools, a TypeScript SDK, and scheduled automations. Compare the specific operations your workflow needs, including task creation, steering, status inspection, and review.
Licensing and Support Requirements
Paradev offers free and paid plans and uses Elastic License 2.0; bb uses MIT. Check the current Paradev plans and bb’s published support arrangements against your requirements.
Pricing
Paradev offers a free tier, Pro at $20/seat/month, and Team ($60) and Ultra ($200) plans with cloud workspaces. bb is free and MIT-licensed, with agents running on your own subscriptions and API keys. In both cases you still pay the underlying providers for Claude Code, Codex, or any compatible agent.
Which Should You Choose?
Choose Paradev if you:
- Want task terminals, branch context, and patch review in one workspace
- Want to work on selected connected hosts through Paradev
- Run scheduled or unattended agent sessions through automations and an SDK
- Want to evaluate Paradev’s paid plans against your team’s support and access requirements
Choose bb if you:
- Want an MIT-licensed, free, self-extending IDE you can mold with plugins
- Like a thread model where agents spawn, steer, and hand off other agents in one view, rather than Paradev's orchestrate skill and session handoff across workspaces
- Want desktop, web, CLI, and API access
- Enjoy building your own workflow tooling with the agent's help
Verdict: Choose Paradev if you want a task workspace around your CLI agents, with terminal context and patch review together. Try bb if its thread model, MIT license, and extensible interfaces fit your workflow. Download Paradev and try a task with the CLI agent you already use, then inspect its diff and preview in the workspace.
Frequently Asked Questions
Do Paradev and bb both use Git worktrees?
Yes. For Paradev, a new local branch-based workspace uses a worktree. bb supports worktree-backed environments. Verify the selected environment in each product; worktrees separate working files but do not guarantee compatible changes.
Is bb open source?
Yes. bb is MIT licensed end to end and free to use. Paradev is source-available under the Elastic License 2.0, with a free tier and paid Pro.
Which agents does each support?
Both are agent-agnostic. Paradev runs Claude Code, Codex, OpenCode, Cursor, Copilot, Gemini, Mistral Vibe, and custom terminal agents. bb supports Claude Code, Codex, Cursor, Pi, OpenCode, Grok, omp, and Hermes, plus any agent that speaks the Agent Client Protocol.
Can either run agents on another machine?
Yes. Paradev supports connected hosts; see remote access setup for plan and online-host requirements. bb’s repository documents remote access options. Compare where execution happens and how the client connects before choosing.
