LANDR
The most established name, and a genuinely good ecosystem: mastering plus distribution, plugins, samples, and collaboration under one subscription. The catch for bargain-hunters: as of July 2026 the free tier is preview-only behind a signup wall, the cheapest download is $10 for one WAV, and your audio is processed on their servers. If you want the whole platform, LANDR earns its price; if you just want a track mastered, you're paying for a lot you may not use. Full TrackGleam vs LANDR comparison →
BandLab Mastering
The most honest free tier among the big names: unlimited masters, no watermark, no per-track fee. The trade-offs, as of July 2026: you must create a BandLab account to download (the master lands in your BandLab projects), audio is processed on their servers, exports are 16-bit regardless of source, and half the presets plus the intensity control require a paid Membership. A fine choice if you're already in the BandLab ecosystem; less so if you want full-resolution WAV without an account.
eMastered
Founded by Grammy-winning engineers and respected for tonal balance and reference matching. It's subscription-only: as of July 2026 the month-to-month plan is $49/month, and the advertised "$19/month" is a 12-month commitment (roughly $156/year if paid upfront). The free tier is a preview after signup — there are no free downloads. Worth it for high-volume releasers who like its sound; expensive for occasional use.
Waves Online Mastering
Built by one of the most trusted names in pro audio plugins, with quality to match the brand. Pricing note worth reading twice: as of July 2026, the advertised "$1.99 per track" is the per-track math of a $71.64/year subscription (36 credits); a single credit is $3.99, and the free tier is a 30-second preview. TrackGleam's AI master is $1.99 flat, one time, no plan — so if that number is what caught your eye, check which version of it you're getting.
CloudBounce
Gone. CloudBounce ceased operations in April 2025 — a business decision by its owner, with the technology folded into FL Studio's FL Cloud. Lifetime license holders were offered an FL Studio license rather than refunds. If you're searching for a CloudBounce alternative, the practical successors are FL Cloud (same engine, inside FL Studio) or a browser tool like TrackGleam — which, running on your device rather than rented cloud servers, has no per-track compute bill and can keep its free tier free.
TrackGleam (that's us)
One job: mastering, in your browser. The free tier is a real downloadable WAV/MP3 — no signup, no watermark, no cap — because all 14 stages of the Gleam Engine V2 run on your device and your audio never uploads. Masters target −14 LUFS / −1.0 dBTP streaming loudness with a volume-matched A/B. The optional AI-Enhanced Master is $1.99 one-time (10 for $5, 100 for $20, $99 lifetime with 50/month fair use), with an automated 14-day money-back guarantee. No distribution, no plugins, no ecosystem — deliberately.
