A practical comparison of Levels.fyi and Glassdoor for salary research in 2026. Data quality, regional coverage, total comp visibility and how to combine both for the most accurate benchmark.

TL;DR

Levels.fyi has the cleanest salary data for software, product, design and data roles at named tech companies, especially in the US, UK and Western Europe. Glassdoor has wider role coverage across industries and stronger small to mid market data, but lower data quality. For an accurate 2026 benchmark, start with Levels.fyi for tech roles and triangulate with Glassdoor, payscale and direct conversations.

Key takeaways

Levels.fyi: deeper, cleaner data on tech companies; weaker outside tech.
Glassdoor: broader coverage across industries and seniority; noisier numbers.
Both under-represent total compensation; equity and bonuses are often missing in user submissions.
Outside major metros, both platforms lose accuracy.
Always combine at least two data sources before negotiating.

If you are about to negotiate a remote salary, picking the right benchmark tool matters. Both Levels.fyi and Glassdoor are free to use and useful, but they collect data very differently. This piece is the side by side comparison most "best salary tools" lists skip.

Coverage

Dimension	Levels.fyi	Glassdoor
Tech roles (eng, PM, design, data)	Excellent	Good
Non tech roles	Limited	Excellent
Equity and stock comp	Detailed	Often missing
Bonuses	Usually included	Often missing
Regional coverage	Strong in US, UK, EU, India	Strong globally
Company specific data	Strong, level mapped	Strong, less normalised
Public sector	Weak	Reasonable

If you are an engineer at a named tech company, Levels.fyi will tell you a more honest story. If you are a non tech professional in a smaller firm, Glassdoor often has more relevant data.

Data quality

Levels.fyi normalises levels across companies (L4, L5, IC4 and equivalents), which makes cross company comparisons sane. Glassdoor uses self reported titles, which makes the same role look messier but covers far more companies.

Both platforms suffer from selection bias: the people who report tend to be the better paid. Plan accordingly.

Total compensation visibility

This is where Levels.fyi shines. A staff engineer might list a base of 220k, a stock grant of 350k over four years and a 60k target bonus. Glassdoor often shows only a base salary range, sometimes flagged as "additional compensation".

If you are negotiating equity heavy roles, Levels.fyi is essentially the only credible free source.

How to combine them in practice

For any salary research session before negotiating, run this quick routine:

Open Levels.fyi for your role, level and metro. Note the median base, equity and bonus.
Open Glassdoor for the same role and metro. Note the median base only.
If they differ by more than 15 percent, search the company on both and read individual entries.
Cross check with a country specific source: Otta, Hired, payscale, Reed (UK), built in (US).
Talk to two practitioners at your level. No tool replaces a 20 minute call.

The number you walk into the negotiation with should be the median of these sources, not the highest you saw.

What both tools miss

Remote salary bands inside companies that pay differently by location.
Sign on bonuses, which often add 10 to 25 percent in year one.
Refresh grants, which materially change senior tech compensation.
Pay rises after one to two years, which are usually below market until you negotiate.
