Labelbox

A training-data platform for labeling, reviewing, and iterating on images, text, video, and documents. Public materials place the company in San Francisco.

7.9/10
Overall Score
Recommend

Recommend for teams that want one platform to label data, bring in experts, and shorten the path from a model idea to a reviewed dataset.

Best for

Enterprise and product teams that need multimodal labeling, expert review, and a faster path from raw data to a model update.

Not a fit

Buyers who only need a one-off labeling crew, or a simple internal spreadsheet workflow.

Verdict

Labelbox is a great fit for teams that need reviewed training data across image, text, video, and documents, with experts in the loop. Pricing is mid-to-enterprise for labeling platforms and tracks seats, volume, and workforce needs. Teams who keep a real review process like having annotation and experts in one place; it shortens the path from a model idea to a reviewed dataset.

Pricing

Labelbox charges on a plan-plus-usage model. Platform work is metered in Labelbox Units (LBUs), and seats, volume, and optional labeling workforce shape what you pay. As of September 2026.

Plan names on public docs include Free, Starter, and Enterprise (plus Education for schools). Exact dollars move with usage and services, so we omit a rate table here.

Review Excerpts

Below are excerpts from public reviews. Paid reviews and pay-for-play sites such as Clutch were excluded.

How it's used

“Before Labelbox, we could train a model pretty quickly and evaluate against validation test sets, but getting data processed and reviewed took forever. Having a strong collaborative expert feedback service helped us get to a weekly iteration cycle.”

What people like

“Labelbox is a gamechanger because of the data quality we can now acquire for our models. It’s hard to imagine a life now without Labelbox.”

What people don't like

“Anecdotally, several CTOs I know intend to lessen their use of Scale, Labelbox and more in the future. Talked to one today who already ditched MTurk for GPT-4 -- cheaper, better, faster was what he said. Labelbox does image annotating still, and one CTO said as soon as GPT-4 enabled this for him he'd have his team homebrew it from there.”

What people don't like

“I tried Labelbox and Langsmith but didn't really help. LangSmith didn't have a good workflow for screen recordings and labelbox also didn't feel like a great option for temporal action sequences. Ended up doing it in a Google Sheet which took me very long per task.”

What people don't like

“Having jumped into the Data annotation field a year ago, I consistently tripped over one thing: setting up annotation tasks in the annotation tool, specifically the Labelbox. I don't have anything against the tools. Once it is configured, it is easy to work on. It feels like I'm solving a puzzle every single time. Time-consuming and complex.”
