Snyk vs GitHub Advanced Security vs Semgrep: Real AppSec Cost per 100 Developers in 2026
The short answer: all three price by the developer, but each defines "developer" differently and only one includes the platform your code lives on. At list price, covering SAST, dependency scanning and secrets scanning for 100 developers costs about $58,800 a year on GitHub's security products, $63,600–$84,000 once the required GitHub base plan is counted, and $90,000 on Semgrep's full stack. Snyk's published Ignite rate implies $126,000 for 100 developers, but Ignite is sold only to organizations under 50 developers, so a 100-developer Snyk price was not publicly listed. The largest cost swing in this category is not the vendor. It is whether you count the base platform, and how many people the vendor counts as a developer.
What each vendor bills
GitHub Advanced Security (OFFICIAL, GitHub announcements). Since April 1, 2025, GitHub sells two separate products, both per active committer per month: Secret Protection at $19 and Code Security at $30. Code Security includes Copilot Autofix, security campaigns and Dependabot features. Both can be bought on the GitHub Team plan without upgrading to Enterprise. Billing follows active committers in the last 90 days across the private repositories where the feature is enabled, and two repositories sharing the same committers do not double-count them. The base seat price is separate: GitHub Enterprise is $21 per user per month (OFFICIAL), and GitHub Team was listed at $4 per user per month (REPORTED).
Snyk (OFFICIAL, Snyk pricing page). Free, Team at $25 per contributing developer per month, Ignite at $1,260 per contributing developer per year (about $105 a month, "starting at", for organizations under 50 developers), and Enterprise at contact-sales pricing. A contributing developer is anyone who committed to a monitored private repository in the past 90 days (REPORTED). Snyk states that products can be bought individually and that plan price varies by product. The Team plan is capped at 10 developers (REPORTED), and free-plan test limits are low (200 open-source tests and 100 code tests a month, REPORTED). Reported Enterprise figures were $15,000–$40,000 for 15–25 developers and $25,000–$60,000 for 25–50 developers (REPORTED); no rates were public above that (QUOTE-ONLY / UNKNOWN). One vendor-comparison page listed Ignite as $1,260 per user per month. Snyk's own page lists $1,260 per developer per year, and that figure is used here.
Semgrep (OFFICIAL, Semgrep pricing page). Teams is priced per contributor per month by module: Code (SAST) $30, Supply Chain (SCA) $30, Secrets $15, or $75 for all three. The free plan covers up to 10 contributors. Teams includes 20 AI credits per developer per month and Enterprise 50 (OFFICIAL). Enterprise, which removes repository and contributor limits and adds on-prem source control support and volume pricing, is custom priced (QUOTE-ONLY / UNKNOWN). Older or alternate Semgrep-hosted pages showed $35, $40 and $50 per contributor, and two current official pages disagree on the free-plan repository cap (10 versus 50), so the current pricing page rates are used and the cap should be confirmed in your quote.
The model
The scenarios are ILLUSTRATIVE: 25 developers with 25 repositories, 100 developers with 100 repositories, and 500 developers with 1,000 repositories. Every developer is assumed to be an active committer, and the target scope is SAST, dependency scanning and secrets scanning. Where Semgrep's free tier covers 10 contributors, the model assumes larger organizations pay for all contributors, which is the conservative reading.
| Annual list cost per developer | Amount | Label |
|---|---|---|
| GitHub Code Security + Secret Protection ($49 × 12) | $588 | OFFICIAL |
| plus GitHub Team base ($4 × 12) | $636 | OFFICIAL + REPORTED |
| plus GitHub Enterprise base ($21 × 12) | $840 | OFFICIAL |
| Semgrep Code + Supply Chain + Secrets ($75 × 12) | $900 | OFFICIAL |
| Semgrep Code + Supply Chain only ($60 × 12) | $720 | OFFICIAL |
| Snyk Ignite ("starting at") | $1,260 | OFFICIAL |
Annual cost by scenario
| Scenario | GitHub security only | GitHub + Team base | GitHub + Enterprise base | Semgrep full stack | Snyk |
|---|---|---|---|---|---|
| 25 developers, 25 repos | $14,700 | $15,900 | $21,000 | $22,500 | $31,500 (Ignite) |
| 100 developers, 100 repos | $58,800 | $63,600 | $84,000 | $90,000 | QUOTE-ONLY / UNKNOWN |
| 500 developers, 1,000 repos | $294,000 | $318,000 | $420,000 | $450,000 (volume pricing not listed) | QUOTE-ONLY / UNKNOWN |
Formula: annual cost = developers × monthly rate per developer × 12. If Ignite's list rate were extended beyond its 50-developer limit, it would be $126,000 at 100 developers and $630,000 at 500, but that is a reference calculation, not an offer. For organizations already on GitHub the base plan is a sunk cost. For organizations hosting code elsewhere, or needing Enterprise features such as SSO, it is a real line.
Cost per 100 repositories
None of the three bills per repository, so a per-repository figure depends on developers per repo. Formula: annual cost ÷ repositories × 100.
| Scenario | GitHub + Team base | GitHub + Enterprise base | Semgrep full stack |
|---|---|---|---|
| 25 developers, 25 repos | $63,600 | $84,000 | $90,000 |
| 100 developers, 100 repos | $63,600 | $84,000 | $90,000 |
| 500 developers, 1,000 repos | $31,800 | $42,000 | $45,000 |
The last row is half the others only because the model has 2 repositories per developer instead of 1. Repository count does not change the bill; developer count does.
First-year versus steady state
Implementation labor is ILLUSTRATIVE: 80 hours of policy and tuning plus 0.5 hours per repository, at a loaded $95 an hour for a security engineer. That is 92.5 hours ($8,788) at 25 repositories, 130 hours ($12,350) at 100 and 580 hours ($55,100) at 1,000. First-year cost is the license plus that labor; steady-state is the license alone. Vendor professional services were not publicly listed for any of the three.
Break-even: security-engineer hours saved
Formula: hours needed = annual cost ÷ loaded hourly cost ($95, ILLUSTRATIVE).
| Scenario | GitHub + Team base | GitHub + Enterprise base | Semgrep full stack | Snyk Ignite |
|---|---|---|---|---|
| 25 developers | 167 hours | 221 hours | 237 hours | 332 hours |
| 100 developers | 669 hours | 884 hours | 947 hours | not available |
| 500 developers | 3,347 hours | 4,421 hours | 4,737 hours | not available |
Per developer per year, that is about 6.7 hours (GitHub with Team base), 8.8 (GitHub with Enterprise base), 9.5 (Semgrep) or 13.3 (Snyk Ignite) of avoided security-engineer time. Triage hours saved by AI autofix or AI triage are the usual source, but neither vendor's savings are guaranteed.
Sensitivity
- Active committer count. GitHub bills active committers, not headcount. If only 60 of 100 developers commit to enabled private repositories, the security products cost $35,280 instead of $58,800, while the base seat is still billed to all 100.
- The Snyk Team cliff. Ten developers on Team cost $3,000 a year. An eleventh moves the organization off Team, and at the Ignite rate 11 developers cost $13,860, 4.6 times as much.
- Semgrep's free ten. If the first 10 contributors are free at 25 developers, the full stack costs $13,500 instead of $22,500.
- Module scope. Dropping Semgrep Secrets ($15) cuts the per-developer cost by 20%.
Budgeting traps
- Seat definitions differ. Active committer, contributing developer and contributor are similar but not identical, and each counts commits to private repositories in a rolling window.
- The base platform is not free. GitHub's security products presuppose GitHub, and Enterprise adds $252 per user per year.
- Test and repository limits. Free and Team tiers cap tests, projects or repositories, so a growing team hits a wall before it hits a price.
- Volume pricing is negotiated. Semgrep Enterprise and Snyk Enterprise list no rates.
What to ask before you buy
Ask each vendor how it counts a developer, which products are included at that price, and what changes above your current headcount. Then compare cost per active committer for the same scope, not the headline starting price.
