CodeSignal vs HackerRank vs TestGorilla: Real AI Hiring Assessment Cost per Candidate
Short answer
CodeSignal's pricing has been genuinely unstable over the past year, which matters for anyone relying on older comparisons: it went fully quote-only in late 2025 (removing public tiers entirely, with a reported $19,000/year Pre-Screen starting point), then reintroduced published self-serve pricing by mid-2026 — Build at $79/month annual (60 credits/year) and Grow at $479/month annual (420 credits/year). HackerRank has maintained transparent, published pricing throughout — Starter at $165/month (10 attempts/month) and Pro at $375/month annual (unlimited users, a 300-attempt cap) — and is reported to often be the lower effective cost per assessment at entry-tier volumes despite CodeSignal's lower headline price. TestGorilla's own $135/month headline is itself a full annual fee displayed as a monthly number, a presentation quirk shared with CodeSignal's pricing page, and its higher tier moves to credit counts settled on a sales call. All three also serve genuinely different hiring use cases, not identical ones.
Pricing at a glance
| CodeSignal | HackerRank | TestGorilla | |
|---|---|---|---|
| Public rate card | Yes, as of mid-2026 — after a period of being fully quote-only in late 2025 | Yes, maintained consistently | Partial — entry tier published, Plus tier settled on a sales call |
| Entry tier | Build: $79/month billed annually ($948/year), or $99/month billed monthly; 60 credits/year (roughly 5/month) | Starter: $165/month, 10 attempts/month (one user, base question library) | Entry tier displayed at $135/month, which is actually a full year's fee divided by twelve for display purposes — not a true month-to-month rate |
| Mid tier | Grow: $479/month billed annually ($5,748/year), or $599/month billed monthly; 420 credits/year (roughly 35/month) | Pro: $375/month billed annually ($4,490/year), or $449/month billed monthly; unlimited users, a 300-attempt cap | Plus: starting price only published; final credit count and cost settled on a sales call |
| High-volume tier | Pre-Screen: a separate, high-volume screening product; reported at $19,000/year for a starter kit during CodeSignal's late-2025 quote-only period — whether this specific figure still applies under the reintroduced pricing structure is unclear | Enterprise: custom-quoted; independent transaction data reports a median contract value around $13,942/year | Enterprise: custom-quoted |
| Billing unit | Credits — consumed per assessment sent, with the specific credit cost varying by assessment type and complexity | Attempts — a capped number per month (Starter) or in total (Pro's 300-attempt cap) rather than a credit system | Credits, though the exact mechanism above the entry tier requires a sales conversation |
| Assessment scope | Broadened beyond pure coding to include Business, Agentic, and Behavioral assessment types, plus AI agents for non-engineering roles — though its "Behavioral Assessments" are explicitly not a validated personality inventory the way some dedicated psychometric tools are | Stayed focused on engineering hiring specifically, including newer "human plus AI" assessments testing whether a candidate can work productively alongside an AI coding assistant, not just solve a problem alone | Broader general-skills and cognitive/personality-style testing, positioned for a wider range of roles beyond pure technical hiring |
| Reported target segment | Competitive with HackerRank for technical hiring at moderate-to-high volume | Favored by larger enterprises, per G2 reviewer patterns | More popular among small businesses, per the same reviewer pattern, and reported to offer lower entry-point pricing for smaller teams or lower volumes |
What headline pricing excludes
CodeSignal's credit system means its listed monthly price is not the real cost of assessing a given number of candidates. Each plan includes a fixed number of credits, and running out mid-month or mid-year requires purchasing additional credits — a real, variable cost on top of the base subscription that isn't reflected in the $79 or $479 headline figures alone.
Neither CodeSignal's nor TestGorilla's advertised monthly price is necessarily a true month-to-month commitment. Both vendors are reported to display a full annual fee divided by twelve as their headline "per month" figure — a buyer expecting to pay that number and be free to cancel after 30 days should confirm the actual billing term directly, since CoderPad's, CodeSignal's own separate month-to-month rate, and HackerRank's plans are the ones genuinely billed monthly without an annual lock-in.
HackerRank's Pro tier includes unlimited users but caps total attempts at 300 — a detail easy to miss when the "unlimited users" framing suggests unrestricted usage. A hiring team with many recruiters needing access, but modest total assessment volume, benefits from this structure; a smaller team running many assessments could hit the 300-attempt ceiling faster than the "unlimited" framing implies.
CodeSignal's pricing history over the past year is itself worth knowing before trusting any specific current figure. The vendor removed public pricing entirely in November 2025, before reintroducing published self-serve tiers by mid-2026 — anyone relying on a CodeSignal price point from late 2025 or early 2026 is very likely working from stale information, regardless of which specific figure they encountered.
Hidden costs
- CodeSignal's extra-credit pricing is reported to cost meaningfully less per unit than the plan's built-in credit rate — a detail that could favor a light overage strategy over jumping to the next full tier, though the exact discount wasn't specified precisely enough in available sources to calculate confidently.
- CodeSignal's Build plan, at $948/year for 60 credits, works out to roughly $15.80 per credit — a real, calculable per-assessment cost that a company should compare directly against HackerRank's Starter plan cost per attempt ($165/month ÷ 10 included attempts = $16.50 per attempt).
- HackerRank's median enterprise contract value, reported at $13,942/year via independent transaction data, is a genuinely useful negotiation reference point for a company entering an Enterprise conversation with HackerRank, since neither CodeSignal's nor TestGorilla's Enterprise tier offers a comparably specific reported figure.
- Actively evaluating a competing platform is reported to be a real, effective lever in this category — buyers who communicate they are considering CodeSignal, HackerRank, or Codility as live alternatives during negotiation are reported to secure better multi-year pricing than those who don't.
Worked scenarios
Cost-per-candidate figures below are calculated directly from each tier's published price and included credit/attempt allowance — not a vendor-provided per-candidate rate, since none of the three publishes one.
100 candidates/year
| Estimated annual cost | |
|---|---|
| CodeSignal Build (60 credits/year included) | $948/year base, plus additional credits needed for the remaining 40 assessments beyond the included allowance — exact overage cost not confirmed from available sources |
| CodeSignal Grow (420 credits/year included) | $5,748/year, comfortably covering 100 candidates within the included allowance, though likely over-provisioned for this specific volume |
| HackerRank Starter (120 attempts/year included, at 10/month) | $1,990/year, comfortably covering 100 candidates |
| HackerRank Pro (300-attempt cap) | $4,490/year, well within the cap but likely over-provisioned for 100 candidates specifically unless the unlimited-user access is separately valuable |
| TestGorilla entry tier | $1,620/year (12 × $135), though the exact assessment allowance within this tier for 100 candidates specifically was not confirmed from available sources |
At this volume, HackerRank Starter's $1,990/year for 120 included attempts is the most directly matched, confirmed fit among the options that clearly state their allowance.
1,000 candidates/year
At this volume, both CodeSignal's Grow tier (420 credits/year) and HackerRank's Pro tier (300-attempt cap) are exceeded, pushing a realistic deployment toward CodeSignal's Pre-Screen product or HackerRank's Enterprise tier, both custom-quoted. HackerRank's reported median enterprise contract value of $13,942/year offers a reference point, though this figure is a general median across HackerRank's enterprise customer base rather than one specifically calibrated to 1,000 candidates/year, and actual cost at this volume could run higher or lower depending on negotiated terms. TestGorilla's Plus tier, with credit counts settled on a sales call, is the more likely fit at this volume among TestGorilla's own tiers, though no confirmed dollar figure exists for it.
10,000 candidates/year
At this scale, all three vendors move into fully custom, negotiated Enterprise territory, and reliable estimates are not publicly available at this specific volume for any of the three. A company at this scale should treat HackerRank's reported $13,942/year median enterprise contract value as a floor reference from a much lower-volume enterprise segment, not as representative of a 10,000-candidate/year deployment specifically.
Normalizing across billing units
CodeSignal's credit system and HackerRank's attempt-cap system are close enough in structure to compare directly on a per-unit basis, provided a buyer confirms whether "1 credit" and "1 attempt" represent equivalent assessment scope (they may not, depending on assessment length and type). TestGorilla's credit mechanism above its entry tier is not detailed enough in available sources to normalize confidently against either competitor.
Break-even and crossover
The clearest calculable finding in this article: CodeSignal's Build plan costs roughly $15.80 per credit ($948 ÷ 60), while HackerRank's Starter plan costs $16.50 per attempt at its monthly rate ($165 ÷ 10) — a narrow gap that several sources describe as making the two "often competitive for similar scopes," with the deciding factor more likely to be feature fit (CodeSignal's broader assessment types versus HackerRank's deeper engineering-specific question library and AI-collaboration testing) than a meaningful price difference at this tier. Above the entry tier, sources specifically note that HackerRank is often the lower effective cost per assessment despite CodeSignal's historically lower headline price — though this gap has narrowed since CodeSignal reintroduced published pricing in 2026.
Who pays more, and when
- A small team needing straightforward technical screening at modest volume can reasonably compare CodeSignal Build against HackerRank Starter directly, given their similar per-unit economics — the choice likely comes down to which platform's specific assessment library and format fits the roles being hired for.
- A larger enterprise hiring team, per reported G2 reviewer patterns, is more likely to already be evaluating HackerRank, and its more specific enterprise transaction-value benchmark ($13,942/year median) makes it easier to budget against than CodeSignal's or TestGorilla's less-documented enterprise pricing.
- A small business or a team hiring for non-technical or broader-skills roles is reported to find TestGorilla's positioning and lower entry-point pricing a better fit than either CodeSignal's or HackerRank's more engineering-centric platforms.
- A team specifically wanting to test whether candidates can work productively alongside an AI coding assistant, rather than testing unaided coding ability alone, should look specifically at HackerRank's newer "human plus AI" assessment format, a capability not described in the same way for CodeSignal or TestGorilla.
- Any team negotiating a multi-year contract with CodeSignal specifically is reported to secure better per-assessment pricing than a single-year commitment — worth raising proactively rather than accepting the first quoted term.
Limitations and uncertainty
CodeSignal's current pricing is confirmed from multiple sources checking its published pricing page as of June–July 2026, following a documented period in late 2025 when it removed public pricing entirely — any comparison predating mid-2026 should be treated as describing a different pricing structure. HackerRank's Starter and Pro tier pricing is consistently confirmed across multiple sources. TestGorilla's entry-tier price is confirmed, but its Plus-tier and Enterprise pricing require a direct sales conversation and were not found published. The reported $19,000/year CodeSignal Pre-Screen starter-kit figure dates from the late-2025 quote-only period specifically, and this article cannot confirm whether it still applies under CodeSignal's current, reintroduced pricing structure. HackerRank's $13,942/year median enterprise contract value is drawn from independent transaction-data benchmarking rather than HackerRank's own published rate.
