This one is less a head-to-head and more a category clarification, because Mudflap and ValveRide Flow do different jobs. Mudflap is a fuel discount network: an app that gets drivers deals at participating truck stops on rates Mudflap has negotiated. Flow is a fuel optimizer: software that decides where each truck should fuel given the route, the tank, state taxes, hours of service, and the discounts the fleet already holds, whoever they are with.
We make Flow, so read accordingly. But the honest answer to 'Mudflap or Flow?' starts with a different question: whose discounts are you trying to use?
Mudflap's published materials describe a free mobile app that gives truckers discounted fuel prices at participating truck stops, with a network weighted toward independents and regional chains. The driver opens the app, finds a participating stop, and unlocks a discount off the posted price. Mudflap negotiates the network rates.
For an owner-operator with no negotiated fuel contracts of their own, that is a genuinely fast first win: you get discounts today that you did not have yesterday, at no software cost.
Flow does not bring its own fuel network and never substitutes its own rates. It takes the discounts a fleet already holds, on WEX, Comdata, EFS, FleetOne, Relay, or direct deals with Pilot, Love's, TA, or anyone else, and enforces them on every dispatch: which stop, how many gallons, at what net price after contract discount and state fuel tax.
The plan lands with the driver by SMS, email link, or in-cab ELD message, keeps re-optimizing as the truck moves, and every claimed dollar is reconciled against the actual fuel card transaction. about $0.90 per gallon in reconciled savings, blended across fleets on Flow.
| Mudflap | ValveRide Flow | |
|---|---|---|
| What it is | Fuel discount network app; deals at participating stops | Fuel purchase optimizer for the whole route and fleet |
| Whose discounts | Mudflap's negotiated network rates | Your own contracts, on every network and chain you already hold |
| Decision logic | Driver picks from in-network deals near them | Engine plans stops and gallons using route, tank, IFTA taxes, HOS, and net contract price |
| Fleet controls | Aimed at drivers and small fleets, per their materials | Dispatch integration, per-driver compliance scoring, anomaly detection, fleet analytics |
| Savings verification | Vendor-reported at time of purchase | 100% of claimed savings reconciled against actual fuel card transactions |
| Price | Free app, per their materials | $25 per truck per month (Solo) to $40 per truck per month (Growth); Enterprise from $49 |

Only partially. Mudflap is a fuel discount network: an app offering deals at participating truck stops on rates Mudflap negotiates. ValveRide Flow is fuel purchase optimization software: it plans where each truck should fuel using the fleet's own negotiated contracts, route, tank, state taxes, and hours of service. A discount network is a source of discounts; an optimizer is what makes discounts get used correctly. Fleets with their own contracts usually get more from enforcing those than from adding another network.
In principle yes, because they solve different problems. Mudflap supplies discounts if you have none of your own. Flow plans the route: even with zero contracts, Flow Solo ($25 per truck per month, by text message) finds the cheapest tax-adjusted diesel along every route, and any negotiated rates you add later get priced in automatically. Flow does not integrate Mudflap's in-app deal prices today; it optimizes against posted retail and your contracted rates.
A network app saves you money at its participating stops. But the cheapest stop for your truck on this route may not be in that network, and fueling in the wrong state can cost more in fuel tax than a discount saves at the pump. Optimization math needs all of it at once: every stop, your real net prices, and IFTA tax differences across the 48 states. That is the job Flow does on every dispatch in under 2 seconds.
Mudflap's materials describe the app as free, monetized through its fuel network. Flow is software: $25 per truck per month on Solo for owner-operators and small fleets, $40 per truck per month on Growth, and Enterprise from $49 per truck per month. The economics question is not the software fee; it is whether your negotiated rates, enforced on every fill across every vendor, beat one network's deals. For fleets that hold contracts, it usually is not close.
