Jackalope vs sizeless: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Jackalope and sizeless — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Jackalope
Jackalope Digital LLC
A desktop workspace for running Codex, Claude Code, Grok, OpenCode, Kimi Code and Antigravity in parallel Git worktrees.
Key features
- Parallel Tasks in Git Worktrees: Every task runs in its own worktree so multiple agents work simultaneously without colliding, with dependencies set when one change needs another.
- Six Supported Agents: Assign Codex, Claude Code, Grok, OpenCode, Kimi Code or Antigravity per task, using each agent's own installed CLI and permission rules.
- Interactive Codebase Map: Browse resolved file dependencies to trace the reach of a change and choose what to inspect next during review.
- Carried-Forward Project Context: Save project guidance once; new tasks match relevant guidelines to the prompt, inherit defaults, and let you inspect what the agent actually received.
- Unified Code Review: Read each result beside its original brief, combine related patches into one review, request another pass, and decide what enters the project.
- Named Account Profiles: Keep work and personal agent accounts separate with per-project defaults and per-account usage tracking.
- Agent Browser and Computer Use: A separate browser session per task lets agents navigate pages, fill forms, capture screenshots and run accessibility checks; Windows desktop control adds approved window clicks, typing and scrolling.
- Cross-Agent Messaging: Tasks share a project inventory with ownership, scopes and dependencies, and agents can send direct task messages or project broadcasts through a durable inbox.
Best for
- Running Experiments Side by Side: Try two different approaches to the same problem with different agents and compare the resulting patches before choosing one.
- Reviewing Agent Output Safely: Keep every generated change behind a human review step, with checks attached to the code they tested.
- Comparing Coding Agents: Assign the same brief to Codex, Claude Code and Grok to see which handles your codebase best.
- Separating Work and Personal Accounts: Use the right provider account per project without re-authenticating or risking cross-billing.
- Understanding a Change's Blast Radius: Use the codebase map to see which files a proposed change touches before merging it.
- Automating Verification: Let agents drive a sandboxed browser to fill forms, screenshot results and run accessibility audits as part of a task.

sizeless
Turns a smartphone video of an open trench into a centimetre-accurate 3D point cloud, CAD as-built plan and GIS-ready digital twin of buried utilities.
Key features
- Smartphone capture: Field crews record an open trench with a standard iPhone Pro — no specialist scanning hardware and no separate surveying appointment
- Centimetre-accurate point clouds: Reconstruction algorithms developed at ETH Zurich build a high-resolution 3D point cloud of the excavation from the video alone
- Standards-compliant CAD output: Generates as-built plans in DWG and DXF, with couplings and pipe runs identified and measurements simplified
- 3D digital twin and GIS export: Produces a model of the pipe route including building entries that drops into existing GIS systems
- Works without GPS: Captures basement sections and building entry points where GNSS-based surveying fails
- Immediate backfilling: Because capture takes minutes, trenches close right after filming instead of waiting on a survey crew
- Documentation in about 72 hours: Complete records arrive weeks earlier than conventional surveying, enabling prompt connection billing
- Third-party utility capture: Records crossing utilities and as-laid geometry as unbroken 3D evidence, replacing hand sketches
Best for
- A utility network operator documenting residential service connections without booking a surveyor for every site
- A contractor closing a trench the same day instead of leaving it open pending a survey appointment
- Capturing a building entry point in a basement where GPS-based surveying cannot get a fix
- A district heating project producing as-built DWG plans for regulatory sign-off
- Spotting a laying error in the 3D point cloud before backfilling, while the fix is still cheap
- Feeding as-built pipe geometry into a GIS system for long-term network maintenance planning
