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.

Algorithm at a glance

X-axis (Core Competencies): Service Focus Ratio + Portfolio Depth + Quality + Experience

Y-axis (360-Performance): Client Reviews + Market Presence + Goodfirms Score

Missing signals are excluded from a firm's score, not substituted with defaults - weights redistribute across remaining inputs

Recency decay over the last 18 months keeps stale reviews from dominating

Eligibility floor: ≥ 1 published review in this category scope

5 countries with the best Value Score for hiring.

Ranked by a composite blending firm count (supply), average rating (quality), and average hourly rate (cost). Affordability is weighted highest (50%), so this surfaces genuinely affordable destinations - not just the biggest markets.

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.

Match by work-hour overlap with your team.

Cost matters - but so does being able to actually talk to your developer during your workday. Here are the best destinations for each major hub.
