Pipeline Estimating,
Re-engineered.
An open-source estimating platform backed by a structured knowledge graph and an AI agent that learns from your historical data — so every estimate you build is smarter than the last.
Built by people who have actually run crews, read bids, and paid for bad estimates.

Jones, your estimating co-pilot.
An AI agent that lives inside your project. Ask it to build a welding crew, stamp a WBS from a template, validate production rates against field benchmarks, or tell you what's missing from scope coverage. Jones doesn't transcribe — it exercises judgment against a pipeline-construction knowledge graph built from real projects.
A workspace built for estimators, not accountants.
VS Code-style tabbed shell. Split panels. Dockable Jones chat. Command palette. Drag a crew tab next to a WBS tab and build in context. Your tools persist per-project — open it tomorrow and everything is where you left it.
Node-centric assignments.
Click a WBS node, see the crews working it, add more right there. No more hunting across modules to connect scope to resources.
Monte Carlo risk analysis — client-side, instant.
5,000-iteration simulations with PERT/triangular/lognormal distributions. Tornado diagrams. S-curves. Spaghetti plots. Runs in your browser. No server bill, no wait.
Map-first scope intake.
Drop a KMZ. See every layer on the map immediately. Categorize and assign crews by geography, not spreadsheets.
Automated review.
Jones scans every estimate for unassigned nodes, production rates that don't match field data, calendar conflicts with shutdowns, template deviations — and writes findings you can review and approve.
A living project wiki.
Every heuristic Jones learns — production rates, terrain effects, seasonal adjustments, crew compositions — gets written to a wiki that grows with your company's institutional knowledge. The HTML export IS the deliverable.
Shared resource libraries.
Global labor and equipment decks maintained once, stamped into every new project. Update a classification's burden rate, and new projects inherit it.
Alpha's battle-tested generation engine. The atomic-record cost model. The calendar system that handles weekly cycles, holidays, shutdowns, and skeleton-crew exemptions. The three-layer data model that made Alpha accurate in the first place.
Beta didn't replace the engine. It built a command center around it.
JetBrains Mono across the board. Warm dark theme that doesn't burn your eyes at 10pm. Data-dense layouts that respect your screen real estate. Every color means something — green for approved, cyan for costs, yellow for warnings, red for errors. No decoration. No dead space.
Beta is a fresh start. Your Alpha projects stay live at the old URL for reference; new work starts in Beta. The global labor and equipment decks you care about came with us — everything else is cleaner, faster, and built for how you actually estimate.
Why We Built This
The major estimating platforms have been rent-seeking for decades. They charge $400/hr for implementation while locking your project data in proprietary silos you can't export without paying again.
We are building the open standard for the $12T construction industry.
If you're an estimator, project manager, or developer tired of working around tools that weren't built for how you actually work — join the Discord. We need domain experts to stress-test the math and builders to help shape the platform.
