Best Browser-Based Color Grading Tools (2026) — No Install Required | Leumos AI
Honest ranking of the 3 best browser-based color grading tools in 2026 — pricing, strengths, weaknesses, and which one fits your workflow.
For filmmakers who don't want to install a 40GB desktop application, the best browser-based color grading tools in 2026 are Leumos AI for AI shot-matching on video timelines, fylm.ai for stills and look-development, and color.io for Hollywood-trained LUT creation. Free tiers start at $0, paid plans range from $7 to $39/mo, and every tool below runs in Chrome on a 4-year-old laptop.
I'm Pravit Gandhi — DaVinci Resolve Certified colourist, BFA in Cinematography, and founder of Leumos AI. I've been color grading commercial work for years, and I built Leumos because I was tired of node soup and 40GB installs choking the editor's laptop on a coffee-shop edit. Every tool here I've actually tested on real footage: FX3 S-Log3, BMPCC 6K BRAW, and the occasional Alexa Mini ProRes file my DP friends throw at me.
How I ranked these
Three criteria. First — does it actually work on a video timeline, or is it a photo tool pretending? Browser color tools have a habit of being single-frame editors with a video export bolted on. Second — what's the realistic upload ceiling and price for a working videographer? Third — does the AI save time on the boring 80% (equalizing exposure across multi-cam), so I can spend my hour on the creative 20%? Speed of install (zero, by definition here) and offline support break ties.
#1. Leumos AI
Browser-based AI color grading — AI scene-cut detection + Match All + Reference Image Grading, no install.
Pricing: Free (2 uploads/day, 400MB) · Creator $15/mo (8 uploads/day, 1GB) · Pro $39/mo (20 uploads/day, 2GB)
I'll be upfront — I built this, and Leumos launches in roughly 30 days from the time I'm writing this. So there are no production case studies yet, and you should weigh that. What I can tell you is what it does: you drop a multi-clip upload in the browser, AI Scene Cut Detection auto-chops it into a shot timeline, then Match All equalizes exposure, contrast, saturation, and hue across the cuts. Drop a still into Reference Image Grading and the look propagates across the timeline. The Preset LUT Library handles the creative push, and Manual Primaries is there when you want to override. The honest weakness — 2GB caps out long-form features and 3-hour podcasts, and there's no offline mode. Chromebook-friendly, globally priced.
Best for: wedding, real-estate, corporate, indie-film, and YouTuber workflows where speed beats nodal surgery.
#2. fylm.ai
Browser-based color tool — strong for stills + look-dev, weaker for video timelines.
Pricing: Free (3 projects) · Lite $7/mo · Pro $15–$19/mo · Team $41–$49/mo
fylm.ai is genuinely impressive on stills — NeuralToneAI does things to a single frame that I'd struggle to replicate in Resolve without ten minutes of nodes. ACEScct support is more rigorous than I'd expect from a browser product, and that matters if you're round-tripping with a DP who shoots Alexa Mini in LogC. The Free tier with 3 projects is enough to evaluate honestly. Where it falls down for me is video — it's a photo-first product, and the DNA shows. There's no AI scene-cut detection on uploaded video, multi-clip shot-matching across a timeline isn't really the workflow it's optimized for, and the $41–$49/mo Team tier is steep if you're solo. If you're a YouTuber doing thumbnails and sequences, you'll feel the split.
Best for: YouTubers who treat color as look-development on key frames more than timeline grading.
Leumos AI launches in ~30 days. The first 500 signups get 50% off the first year — join the early-access list.
#3. color.io
PWA color tool with Hollywood-trained LUTs — joy to use for stills + LUT creation.
Pricing: Free · Pro $99/year (~$8/mo)
color.io is the tool I keep open on my iPhone. It's a PWA, it works offline, and the Hollywood-trained LUT library is the best in the browser category — you can feel the trained-on-real-feature-film fingerprint when you push the grade. AI Match is solid on stills, and at $99/year the Pro tier is the cheapest serious entry point on this list. The honest caveats: the UX leans photographer, which trips up video editors who expect a timeline-first layout. There are no layers or masks for surgical grading, batch editing across sequenced video frames is weak, and it's fundamentally a look-development tool, not a shot-by-shot timeline grader. If you want to invent a look on a still from your BMPCC 6K and then export the LUT to Resolve, color.io is wonderful. If you want to grade 47 wedding clips before Monday, it's not the workflow.
Best for: YouTubers and indie-film look-dev, LUT creation, and mobile grading on iPhone.
Decision framework — which one for which job?
If your work is multi-clip video timelines — weddings, real estate, corporate, indie-film dailies — you want AI scene-cut detection and Match All in the browser, which is Leumos's lane. If your work is stills, single-frame look-development, or you're a YouTuber whose grade lives on thumbnails and hero frames, fylm.ai's NeuralToneAI is hard to beat at $7–$19/mo. If you want the most accessible Hollywood-LUT vocabulary, offline iPhone use, and you're inventing looks to export back into Resolve, color.io at $99/year is the deal of the category. Pro colorists — yes, AI matching is approximate. But it saves 80% of equalization time, which is the part you don't enjoy anyway.
FAQ
Can browser-based color tools actually handle ProRes and BRAW?
All three handle proxy-friendly delivery formats well, but raw camera-original BRAW and ProRes get transcoded on upload. For Leumos specifically, the 2GB Pro cap means you'll proxy down before upload — a quick H.264 export from your NLE is the realistic workflow. fylm.ai and color.io similarly prefer compressed inputs. If you need to grade native BRAW from a BMPCC 6K, you're still better off in DaVinci Resolve for that step, then using a browser tool for look-development or shot equalization on the proxy timeline.
Are these a replacement for DaVinci Resolve?
No, and I say that as someone Resolve-certified. Resolve still wins on nodal precision, tracking, noise reduction, and finishing for delivery. What the browser tools win on is speed for the 80% — getting a multi-cam wedding equalized, getting a YouTube sequence consistent, getting a look established quickly without booting a 40GB application. Use the browser for fast pass and look-dev, use Resolve when you need surgical control or you're delivering for theatrical or broadcast spec.
Which tool is best if I'm on a Chromebook or low-end laptop?
All three run in Chrome, but Leumos and color.io are the most accommodating to low-spec hardware because the heavy compute runs in the cloud. fylm.ai is also browser-native but its photo-first interface can feel sluggish with larger video uploads on older machines. color.io has the unique advantage of being a PWA that installs and runs offline on iPhone, which is genuinely useful if your laptop is the bottleneck and you're grading on the go.
What about free tiers — can I get real work done without paying?
Yes, for evaluation and small jobs. Leumos Free gives you 2 uploads/day at 400MB, which is enough to grade short reels and test the AI Scene Cut Detection and Match All workflow. fylm.ai Free covers 3 projects, fine for trying NeuralToneAI on stills. color.io Free is generous enough that I used it for months before considering Pro. For a paying client deliverable workflow, plan on $15/mo (Leumos Creator) or $8/mo equivalent (color.io Pro annual) as the realistic entry point.
How does Reference Image Grading actually work in practice?
You drop a still — a film frame, a photograph, a previously-graded shot — and the tool analyzes its color profile and applies a matching grade to your footage. In Reference Image Grading, the Leumos workflow is: upload your clips, drop the reference still, and the look propagates across the AI-detected scenes. It's approximate, not magic — you'll still want Manual Primaries for final tuning. But for a wedding videographer trying to match a Pinterest mood board across 40 clips, it saves the hour you'd otherwise spend eyeballing curves.
