Comparison
OSOWloads vs oversize.io
OSOWloads and oversize.io both turn the state-by-state rules behind an oversize or overweight move into the numbers you quote from: permit costs, escort triggers, weight limits. oversize.io is the established player, longer track record and bigger customer base. OSOWloads runs about half the per-calc cost, is built by an active OS/OW brokerage owner, and adds a bid builder, per-state road tier overrides, and escort smoothing oversize.io doesn't document publicly.

Feature-by-feature comparison
Whether OSOWloads is a real oversize.io alternative comes down to this: same core job, less per calc, plus a few things oversize.io doesn't do. Here is where they genuinely differ. Where oversize.io's behavior is not publicly documented, we say so rather than guess.
How we compared
Three inputs went into this: the public oversize.io pages and published interviews, OSOWloads product data, and the day-to-day of actually quoting OS/OW loads. Where oversize.io does not publicly document something, we mark it not advertised rather than assume it is missing. Pricing and feature claims are current as of May 29, 2026.

What OSOWloads does better
Six things we built on purpose because we hit the problem ourselves.
Bid Builder
A sidebar tied to the calc result. Truck $/mi, escort $/mi, police, survey, OD premium, margin %. Settings persist between calcs. The output is a number you can send to a shipper in a professional PDF, configured with whatever pass-throughs (or none) as you please.
Smart escort smoothing
Three modes for how escort miles roll across state lines: raw per-state, conservative, and full-carry. Escorts often have to stay with the load through a state that requires zero, and the real cost includes day rates and hotels on top of the per-mile. The modes account for that.
Per-state road tier override
Switch a single state's road classification without re-running the calc. Some states have one tier. CA, ID, CO and others have three to five. You might have a PU/DEL 50 miles from interstate on 2-lane, so why model the whole route as interstate or non-interstate?
Interstate preference slider
Drag the slider to bias the route fetch toward more interstate or more non-interstate miles.
Waypoint routing
Force the route through a specific stop or checkpoint. Useful for known route issues, construction avoidance, or state DOT route policy.
Built by a brokerage owner
The product is built by someone who owns and runs an active open deck & OS/OW brokerage. Per-state rules trace back to DOT permit manuals, admin code, and statutes — 400+ source files, 19 distinct overweight fee models built to match each state's actual structure. Bugs get fixed by the person who built the thing.
Why this exists
Built to spare you the mistakes I made.
The escort smoothing logic, the road tier overrides, the per-state OW fee models, the waypoint routing aren't features for show. Each one is there because something on a real load went wrong and there was no tool to catch it.
The point of the product is to cut the learning curve. You should not have to lose money on the same loads I did to figure out how this work is actually priced.
What oversize.io does better
They're the incumbent, and that counts for something.
- Frost Laws sections
- Longer track record, founded by a former heavy-haul dispatcher and broker.
- Larger customer base, including major asset carriers.
- RFQ workflow tools for OS/OW quoting teams, including manager review of outbound quotes and rep performance tracking.
- Canada coverage for cross-border OS/OW work.
However
At every published tier, oversize.io costs more per calc. The Bid Builder is the bigger gap though. It is a repeatable flow that walks you from calc to quote without a spreadsheet, builds visibility into every cost component along the way, and shows the state-by-state overweight pricing model in a dedicated panel so you can see why a quote came out the way it did. Add the escort smoothing logic, rule-based OD premiums, GVW prediction, per-state road tier override, interstate preference slider, waypoint routing, and that is the gap OSOWloads is built to fill.

Free state data, two ways in
Both products publish free OS/OW reference data. OSOWloads gives you two ways in. When you just need one number fast, there is a clickable US map: tap a state, get the legal height, the first-escort width, the DOT contact. When you want the whole picture, every state gets its own page: legal limits, fees, escort triggers, the axle table, and the permit office, all in one place. oversize.io works one state page at a time.
A full page per state. Legal limits, fees, escort triggers, axle table.
Tap a state, see the height limit.
Phone, portal, links for all 48. 2026 info that's accurate.
Want to run only non-escort loads? Easy.
THE most comprehensive list of per state annuals info, one page, easy to navigate.
Run any axle layout against per-state limits and the bridge formula.
Thinking about switching from oversize.io?
Choose OSOWloads if
- You mostly quote US oversize and overweight loads
- You care about cost per calc (about half the per-calc rate)
- You want a bid builder tied straight to the route result
- You want customer-facing quote PDFs you fully control
Choose oversize.io if
- Your lanes cross into Canada
- Your team already runs on its RFQ and quote-review workflow
- You want the larger, longer-established platform
If you mostly run US loads and want to pay less per calc, OSOWloads is a straightforward oversize.io alternative: the same core route-and-permit job, about half the cost per calc, plus the bid builder, escort smoothing, and per-state road tier overrides.
If your lanes cross into Canada, or your team already lives inside oversize.io's RFQ workflow, the switch is harder to justify, and we'd rather say that than pretend otherwise. The free plan (3 calcs a month, no card) is there so you can run a real load and see for yourself before you move anything.
Frequently asked questions
Is OSOWloads a good oversize.io alternative?
For US oversize and overweight work, yes. OSOWloads does the same core job, per-state permit costs, escort triggers, and weight limits, at about half the per-calc cost, and it adds a bid builder, escort smoothing, and per-state road tier overrides. If your lanes cross into Canada, oversize.io still has the edge.
How much does oversize.io cost compared to OSOWloads?
oversize.io publishes plans starting at $59/mo for 25 calcs, about $2.36 each. OSOWloads runs $19/mo for 15 calcs, $59/mo for 50, and $119/mo for 100, between $1.18 and $1.27 per calc. At every published tier OSOWloads costs less per calc, and it has a free plan: 3 calcs a month, no card.
Does OSOWloads cover Canada?
No. OSOWloads covers the 48 contiguous US states. If your lanes cross into Canada, oversize.io is the better fit for that cross-border work. For US-only OS/OW quoting, OSOWloads is built end to end.
What can OSOWloads do that oversize.io does not?
A bid builder tied to the route result, escort smoothing across state lines (raw, conservative, full-carry), per-state road tier overrides, an interstate preference slider, waypoint routing, and fully customizable customer-facing quote PDFs. oversize.io does not publicly document these.
Can I try OSOWloads before switching?
Yes. The free plan gives you 3 calcs a month with no credit card and every feature unlocked. Run a load you have already quoted by hand and check the number before you move anything.
Run a real calc.
Free. No card required.
No demo call, no credit card. Sign up, paste a route, and see if the number agrees with what you would have built by hand. The free plan gives you three calcs every month.
