How firms are placed on the matrix

Every position on this chart is the output of the Goodfirms ranking algorithm - a weighted composite of signals across two axes. The algorithm is recomputed regularly and is fully documented.

Sponsorship does not affect placement. PRO members receive visible badges and ad placements, but their algorithmic scores are calculated identically to free listings.

What the gap actually buys you

The rate gap between the highest- and lowest-cost regions is largely a cost-of-living and labor-market gap - not a quality gap. Top-tier firms in lower-cost regions routinely deliver work competitive with premium markets at a fraction of the cost.

That said, time-zone overlap, language alignment, and IP protection vary by region. Eastern Europe and LATAM hit a sweet spot: meaningful cost savings with same-day overlap for US/EU clients.

~70%

Typical cost savings when moving a $100K/year dev contract from a premium market to a top value destination - comparable skill, comparable delivery quality.

How the heatmap is built

Every cell in the grid above is the count of firms in (place × hourly-rate tier). Firms are placed by their published hourly rate; those without a disclosed rate are not plotted.

Top company names per cell are surfaced by Value Score - a weighted blend of affordability (50%) + rating (35%) + review volume (15%).

The "Best" ribbon marks the cell in each row where firm density, ratings, and affordability line up best - the densest, highest-quality combination.
