Carly Alternative Without Subscription: 5 Apps for BMW & Mercedes (2026)

You bought Carly for the BMW or Mercedes coding, but the yearly licence (about €65-105 for one brand, about €104 for BMW) is grating after the first renewal. Or you haven't bought Carly yet and the recurring cost is the dealbreaker before purchase. The good news: BMW owners have a clean one-time-payment alternative at about €50 in BimmerCode that matches Carly's coding depth at a fraction of the long-term cost. Mercedes owners have fewer options - subscriptions remain harder to escape - but workable paths exist. This guide breaks down five real Carly alternatives without subscription, what each replaces, and which fits your exact use case.

Carly alternatives at a glance

Notice the column gap: only BimmerCode offers a true coding alternative to Carly without a subscription. Carista also codes across brands, but that normally means its Pro subscription (the one-time in-app option it mentions has no published price), and its depth is meaningfully shallower. For Mercedes specifically the gap is even wider because no BimmerCode-equivalent exists for Mercedes.

Is BimmerCode the real Carly replacement for BMW?

For BMW owners, yes. BimmerCode is the standard recommendation in every BMW forum thread asking about Carly alternatives, and the reason is straightforward: same coding depth, one-time payment, no app-specific adapter required.

How it works: BimmerCode is free to download, and the full version is a one-time in-app purchase of about €50 on iOS and Android. It works with many off-the-shelf Bluetooth OBD2 adapters (the OBDLink MX+ is the gold-standard pairing at ~€60, but adapters in the €25-40 range also work if BimmerCode-supported). Companion app BimmerLink (~€40 one-time, same developer) handles diagnostics: fault codes, live data, service resets, freeze frame data. Total all-in: ~€90 + adapter, one-time, forever.

What BimmerCode covers on BMW: ambient lighting customisation (full color spectrum modes Carly also exposes), M-Sport gauge displays, iDrive UI changes, daytime running light to turn signal mods, sport display gauges (BMW left disabled at factory), comfort menu unlocks, exhaust burble on M-Sport variants, video-in-motion enables, digital instrument cluster layouts on later models with iDrive 7+. Depth is comparable to Carly's BMW package.

What BimmerCode doesn't cover: Mercedes, Audi, VW, anything not BMW. It's BMW-only and that's the explicit positioning.

5-year cost comparison for BMW coding (Carly's adapter is included in the licence, so the licence is the whole cost):

• Carly BMW licence: about €104/year × 5 = approximately €520
• BimmerCode + BimmerLink + adapter: about €50 + €40 + ~€40 = about €130 total, zero ongoing

The roughly €390 saving over 5 years is the headline. For BMW-only owners, BimmerCode is the no-subscription Carly replacement.

Carly alternative for Mercedes without subscription: what actually works?

Honest answer: Mercedes coding without a subscription is harder than BMW coding because no Mercedes equivalent of BimmerCode exists at the consumer price point.

The realistic options:

Carista (Pro about €60 a year; adapter about €30-70): Provides basic Mercedes coding plus VAG and BMW coverage. Coding normally runs on Carista Pro, a subscription at about €60 a year (about €100 for two years). Carista says its EVO adapter unlocks diagnostics permanently and mentions a one-time in-app option too, but publishes no price for it, so check the price in the app before counting on a no-subscription route. Coverage is shallower than Carly's Mercedes package - you get the most-requested features (ambient lighting, engineering menu unlock, basic comfort coding) but not the full Carly depth. SD Connect clone + XENTRY/Vediamo (advanced, €150-400): The Mercedes-specialist route: a clone of the SD Connect C4 or C5 multiplexer running Mercedes dealer software (XENTRY for diagnostics, Vediamo or DTS Monaco for coding). Requires a Windows laptop, a long setup, and the licensing of the software is a grey area. Used by Mercedes specialists and serious DIY mechanics. Not a consumer-friendly path. Stay on Carly: The realistic path for many Mercedes owners. If Mercedes coding is your primary need and Carista's depth isn't enough, paying Carly's subscription is the way to keep full coding depth. The Mercedes licence (about €75 a year, adapter included) is offset by the polished interface.

For Mercedes diagnostics WITHOUT coding (just fault reading, live data, used car health checks), any generic-adapter OBD2 app is the free path; only coding is the gap.

If diagnostics rather than coding is your real need, the only thing you have to buy is the adapter. Skanyx works with any standard Bluetooth OBD2 adapter (€15-60): a free tier for reading and clearing codes and full live data, Pro at €12.99/month or €69.99/year, and a credit-based 8-step Pre-Purchase Inspection with a PDF report if you are checking a car before buying it.

Can I use OBDeleven instead of Carly for BMW?

Technically yes, but you're trading down. OBDeleven's BMW coding is functional but materially shallower than its VAG (VW/Audi/Skoda/Seat) coverage. The one-click app catalogue for BMW is much smaller than for VAG vehicles.

If you specifically want to drop Carly for BMW coding, BimmerCode at about €50 beats OBDeleven at about €85 device + credits/subscription on both depth AND cost.

The case for OBDeleven over BimmerCode: you also drive a VAG vehicle (Golf, A3, Octavia, Ibiza). In that case, OBDeleven gives you full VAG depth plus adequate BMW coverage in one app and one adapter. If your household has BMW + VAG, OBDeleven Credits (no subscription, pay per coding session) is the cheapest path that covers both ecosystems.

Carista: the multi-brand coding option

Carista covers coding for VW, Audi, Skoda, Seat, BMW, Mini, Toyota, Lexus, and Scion. Coding runs on Carista Pro, a subscription at about €60 a year (about €100 for two years). Carista says its EVO adapter unlocks diagnostics permanently and mentions a one-time in-app option too, but publishes no price for it, so we cannot quote one here.

How it works: Carista provides the app plus its own Bluetooth OBD2 adapter (the OBD Reader at about €30 or the EVO at about €70, compatible with Carista only). Pro unlocks coding for all supported brands. Coverage is broad but noticeably shallower than Carly on BMW/Mercedes or OBDeleven on VAG; you get the most-requested coding features per brand rather than the full depth catalogue.

Pricing reality: there is no published Carista lifetime price. If the one-time in-app option appears for your car, check its price in the app before buying; otherwise budget for Pro at about €60 a year, which over 3-5 years costs well over BimmerCode's one-time price.

Trade-offs: shallower coding depth per brand than dedicated tools. Adapter is Carista-proprietary (another lock-in to consider). For multi-brand basic coding needs, this is the broadest option; for deep coding on a single brand, dedicated tools beat it.

Choose Carista if: you have multiple vehicles across BMW + VAG + Toyota, want basic coding on all of them in one app, and accept a Pro subscription unless the one-time in-app option is offered for your car.

Is there a free Carly alternative for BMW or Mercedes diagnostics?

For diagnostics and pre-purchase inspections, yes. For coding, no.

What a generic-adapter OBD2 app replaces from Carly's feature set:

• Powertrain fault code reading and clearing with plain-language descriptions
• Live data on the standard OBD2 PIDs: fuel trim, MAF, MAP, O2 sensors, RPM, coolant temp
• Readiness monitor status, which is what tells you whether the car will sit its emissions test
• A used-car health check, which is the Carly feature most owners actually opened the app for

What no generic-adapter app replaces:

• Coding of any kind (iDrive UI, ambient lighting, sport displays, comfort settings, engineering menu access)
• Manufacturer-specific feature unlocks
• Multi-module ECU scanning across ABS, airbag, BCM and gateway modules (Carly reads these via brand-specific protocols; generic OBD2 does not)
• Manufacturer-extended PIDs on Mode $22 (BMW swirl flap actuator position, NOx sensor cluster, individual injector trim, etc.)

Car Scanner ELM OBD2 covers the free end of that list on both iOS and Android. If your Carly use was 80% used car checks plus diagnostics and 20% occasional coding, a generic app covers the 80% and BimmerCode at about €50 covers the BMW coding separately.

Are Torque Pro and Car Scanner ELM viable Carly alternatives?

Only if your Carly use was diagnostics-only. Neither app does coding.

Torque Pro at about €4 one-time (Android only) is the gold-standard Android raw data and PID logging app. If you used Carly mainly for live data monitoring, custom dashboards, or PID export, Torque Pro on Android is materially better and costs about €4 total forever. See Car Scanner vs Torque Pro for the Android-side breakdown. Car Scanner ELM OBD2 is iOS + Android, has a genuinely useful free tier, polished interface. Pro upgrade is about €9 one-time (or about €5 a year) with optional in-app manufacturer modules. Best free OBD2 app overall in 2026.

Neither does coding. If you primarily used Carly for unlocking BMW or Mercedes features, these are not the alternatives. Stay focused on BimmerCode (BMW) or Carista (multi-brand basic coding, normally on a Pro subscription) for the coding requirement.

What are the deal-breakers nobody talks about?

Five Carly-alternative gotchas that show up in BMW and Mercedes forums:

BimmerCode adapter pairing is finicky on iPhone. Apple iOS only supports Bluetooth Low Energy (BLE) adapters, and not every BimmerCode-compatible adapter works on iPhone. Check the listing carefully or buy directly from the BimmerCode-recommended adapter list. On Android, Classic Bluetooth adapters work fine. Mercedes Carista coverage is shallow. If you read Carista's marketing, you'd think it's a Carly replacement for Mercedes. In practice, Carista's Mercedes coding library is smaller than even OBDeleven's BMW coverage (which is also shallow). For deep Mercedes coding, no good no-subscription alternative exists. An unredeemed OBDeleven credit code expires after a year. Credits already in your account do not expire while the account stays active, but a credit code bought on the OBDeleven website is lost if you have not redeemed it within one year of purchase. Redeem a code as soon as you buy it. Carista has no published lifetime price. Carista mentions a one-time in-app option but publishes no price for it, and Pro is a subscription at about €60 a year (about €100 for two years). Check the price in the app before assuming a one-time route exists for your car. Budget a separate adapter for BimmerCode. Do not plan BMW coding in BimmerCode around the Carly Universal Scanner: use an adapter BimmerCode lists as supported (~€25-60). The Carly dongle is not scrap, though. It works as a standard OBD2 adapter for generic diagnostics (fault codes, freeze frame, standard live data, VIN) in generic OBD2 apps, ours included, just not for coding or brand modules.

Which Carly alternative should you choose?

Decision tree:

BMW owner, want coding without subscription: BimmerCode + BimmerLink (about €90 one-time + adapter). The clearest pick on this list. Mercedes owner, want coding without subscription: Carista (Pro about €60 a year, or its one-time in-app option if your car is offered one; no published price), or accept Carly's licence (about €75 a year for Mercedes). Realistic options are limited. Multi-brand household (BMW + VAG): OBDeleven Credits if BMW coding needs are light; Carista if multi-brand basic coding is acceptable depth. Want diagnostics + used car check (Carly's PPI-equivalent feature), not coding: any generic OBD2 app on a standard adapter. Car Scanner ELM OBD2 is the free baseline; the paid apps in this bracket add interpretation and a structured used-car report on top of the same data. Want Android raw data and PID logging: Torque Pro about €4 one-time. Not a coding alternative but unbeatable for what it does. Want a polished iOS+Android free diagnostic app: Car Scanner ELM OBD2. Primary BMW coding only, don't care about depth: Stick with Carly. The interface is the most polished and the multi-brand subscription pays for itself if you might add another European vehicle later.

Verdict: best Carly alternative without subscription in 2026

For BMW: BimmerCode at about €50 one-time is the clear answer. For Mercedes: options are limited and Carista is the realistic budget path, though its coding normally runs on a Pro subscription. For diagnostics rather than coding, a generic OBD2 app on a €15-60 adapter is enough, and the free tiers cover fault codes and live data at zero cost. Pick by car AND by whether your real need is coding or diagnostics.
