Quick answer
RedTrack is our top pick for most people. The default first tracker for most direct-response buyers: CAPI on every plan, ad-level spend sync, and an entry price a solo operator can carry.
- RedTrack. Best for Multi-channel paid-social buyers. Has a free tier.
- Voluum. Best for Affiliate and native/pop/push buyers. From $119/mo.

RedTrack: pros and cons
What works
- Server-side CAPI for Meta, TikTok, Google and Snapchat is included from the $69 Builder plan, where several rivals gate it behind four-figure tiers.
- Ad-spend sync down to the ad level means ROAS and CPA reflect what was actually spent, not a number hours out of date.
- Sits between a pure click tracker and a revenue-attribution suite, so one tool covers affiliate offers and owned DTC.
- Published, tiered pricing all the way up to Agency, so you can forecast cost as you scale seats and events.
What to watch
- The fresh ad-spend sync speeds (5 and 15 minute) and the Ads Manager control layer are paid add-ons on top of the plan, so the real monthly cost at scale runs above the headline price.
- It is a media-buying tracker, not a full multi-touch attribution suite for long, call-heavy sales cycles; buyers who need that look at Hyros.
- Setup still asks for clean UTMs, working pixels and CAPI hygiene. It surfaces tracking gaps, it does not paper over them.
Voluum: pros and cons
What works
- Deep click-routing and traffic-distribution rules built for zone, publisher, GEO, device and sub-ID optimization.
- Cookieless tracking and S2S postbacks that hold up on redirect-style affiliate flows where browser pixels fail.
- The Anti-Fraud Kit flags suspicious traffic automatically, which matters most on native and pop inventory.
- Cloud-hosted with automatic migration from an old tracker, so there is no server to run.
What to watch
- The automation layer, Automizer, is billed separately from $375/mo on top of the plan, so real automation costs stack fast.
- Full server-side CAPI depth and higher event ceilings sit on the expensive upper tiers ($539 to $1,599/mo).
- It is built around click routing and offer/lander optimization more than ecommerce customer-journey attribution.
What each one costs
RedTrack. From $83 per month. Affiliate and lead-gen plans are priced by events and seats. Solo is $141/mo billed yearly ($169 monthly) with 5M events and one user. Team is $333/mo ($399 monthly) with 20M events and five users. Enterprise is $833/mo ($999 monthly) with 75M events and fifteen users. Overage costs $0.04 per 1,000 events on Solo, $0.035 on Team and $0.025 on Enterprise, and tracking keeps running past the cap. Ecommerce plans are priced by tracked revenue: Relay is free with UTM-based last-click attribution, Brand starts at $83/mo billed yearly ($99 monthly) and Agency at $499/mo ($599 monthly). Faster ad-spend sync is a paid add-on. Paid plans start with a 14-day free trial.
Voluum. From $119 per month. Profit costs $119 a month billed annually and includes 1M events. Scale costs $299 a month billed annually for 5M events. The pricing page shows no month-to-month figure. Events over the Profit limit bill at $0.06 per 1,000.

How we compared these
We do not run paid campaigns through either tool. We read each vendor's own documentation and pricing, verify every number against the source, and weigh the long-term reports of operators who run them at real spend. The full rubric is on the methodology page.
