Meta-analysis software in your browser

Run a complete meta-analysis without installing anything: effect sizes, forest and funnel plots, heterogeneity, subgroups, and the systematic review workflow around them.

A complete meta-analysis, no R required

Covexe runs the analysis most researchers otherwise need R, Stata, or a paid desktop package for. Upload your study data as CSV or Excel, choose an effect measure (odds ratio, risk ratio, hazard ratio, mean difference, or standardized mean difference) and a fixed-effect or random-effects model, and you get the pooled estimate, a publication-ready forest plot, and the full heterogeneity picture: Cochran's Q, I², and tau² with DerSimonian-Laird or REML estimation.

Beyond the pooled estimate

Numbers you can defend

Every method is validated against R (metafor for pairwise meta-analysis, netmeta for networks), and every result shows the formula and the citation behind it. You can download R replication code for the analysis, so a reviewer or supervisor can reproduce your numbers independently.

The steps before the analysis live here too

Most free meta-analysis calculators start and end at the forest plot. Covexe covers the review around it: question framing and search strategy, abstract screening with a second reviewer and Cohen's kappa, AI-assisted data extraction from PDFs, risk of bias assessment (RoB 2, ROBINS-I, NOS, JBI, AXIS), GRADE certainty ratings, and the PRISMA 2020 flow diagram that documents it all. One project, one place, free core tools.

How it compares

RevMan is free but built around the Cochrane workflow. Comprehensive Meta-Analysis costs 495 to 1395 USD and runs on the desktop. R is free and powerful but asks you to code. Covexe sits in the gap: point and click in the browser, statistics checked against R, and the systematic review workflow included rather than sold separately.

Frequently asked questions

Do I need to know R or any programming?

No. The analysis is point and click. If you want code, you can download R replication scripts for your analysis.

How do I get my data in?

Upload a CSV or Excel file. Each tool includes a worked example showing the expected format.

Is it really free?

The core tools are free: screening, risk of bias, meta-analysis, GRADE, and PRISMA. Optional AI features are metered on the free tier, or you can bring your own API key.

How is this different from RevMan or CMA?

RevMan is free but built around the Cochrane workflow, and CMA is a paid desktop package. Covexe is free at the core, runs in the browser, and includes the screening-to-PRISMA workflow around the statistics.
