Alkali vs SteelFlo
How Alkali and SteelFlo compare on detection breadth, integrations, pricing, and field results for steel estimators in 2026.
01 · In short
Alkali
Alkali is the closest direct comparison to Lift on member coverage. It detects the same six categories of structural steel and runs AISC weight math automatically. It also supports collaborative bid markup. Its Column Scanner ships as a named feature, a gap Lift is still closing.
SteelFlo
SteelFlo is the price-sensitive entrant. It pitches a five-minute target time and caps monthly takeoffs, with beta pricing framed as 'lock in current rates before prices increase'. The tool supports six standards out of the box (AISC, EN, BS/IS, AS/NZS, GB, SSMA) and reads finish callouts. It is going after small shops before the larger products notice them.

04 · What each does well
Alkali
- Wide member coverage, including base plates and miscellaneous steel.
- Column Scanner shipping as a named feature, with stock-aware nesting downstream.
- Real-time collaborative estimating with live cursors.
- Aggregate footprint: 7% of monthly U.S. structural steel volume runs through the product.
SteelFlo
- Lowest entry pricing in the category, starting at $399/mo.
- Multi-standard support (AISC, EN, BS/IS, AS/NZS, GB, SSMA) out of the box.
- Coating and finish detection from labels and page-level notes.
- Patent-pending positioning and aggressive search marketing, including bids on competitors' brand terms.
05 · Limitations
Alkali
- Public pricing not disclosed.
- Throughput claims are aggregate volume, not customer-by-customer outcomes.
- Elevation telemetry is less battle-tested than Lift's.
SteelFlo
- Per-month takeoff caps. Enterprise tops out at 30 takeoffs a month before overage logic.
- Detailed customer base not yet visible, with one named reference on the homepage.
- Integrations limited to CSV and Excel today, with no native Tekla or Strumis pipe.
- The beta-pricing rhetoric implies a price reset is coming.
The take
Alkali and SteelFlo both let estimators run their own takeoffs, at different tiers. SteelFlo is the budget option, with transparent published pricing and six structural standards. It is capped by monthly takeoff limits and CSV-only export. Alkali covers more members and adds a Column Scanner, collaboration, and nesting, and it exports to Tekla and Bluebeam. Its pricing isn't published. Take SteelFlo for a small shop watching cost. Take Alkali for a shop that needs breadth and downstream integration.
