A Comparison of Aikido Security, Snyk, and Semgrep

We compare Aikido Security, Snyk, and Semgrep across coverage, noise, developer experience, and pricing predictability, and tell you which one to pick for your team.

Written by Jean-Frederic Mainville

Every team building software eventually asks the same question. Which application security tool should we actually pay for? The market answers with a wall of feature matrices that all look identical. SAST. SCA. Secrets scanning. IaC scanning. Checkmarks everywhere. That's not useful. Feature checklists don't tell you which tool your developers will actually use six months from now.

We've implemented and lived with Aikido Security, Snyk, and Semgrep across different client engagements. Here's our honest, opinionated take.

TLDR

  • Small or mid-sized teams that want broad coverage without a dedicated AppSec engineer should pick Aikido Security.
  • Teams that want the best static analysis engine and are willing to invest in tuning custom rules should pick Semgrep.
  • Larger organizations that already run on Snyk's vulnerability intelligence and need deep IDE and ticketing integrations should stick with Snyk, but budget for it carefully.

Aikido Security

Aikido's pitch is "one dashboard instead of five vendors," and it mostly delivers. It bundles SAST, SCA, secrets detection, container scanning, IaC scanning, and cloud posture checks into a single product, and it leans on proven open-source scanning engines under the hood rather than reinventing every detector from scratch. The value isn't in a proprietary engine. It's in the noise reduction layer on top, an auto-triage system that groups and deprioritizes findings that aren't reachable or aren't exploitable in your context.

For a small team without a dedicated security hire, this matters more than engine sophistication. You get set up in an afternoon, and findings arrive already prioritized.

Pricing

Aikido's model is simple to reason about. There's a limited free tier for individual repositories, then paid tiers priced per active developer that unlock the full scanner suite, higher scan frequency, and integrations like Jira and Slack. Enterprise-tier add-ons like SSO, custom roles, and compliance reporting sit on top of that. Because the price scales with headcount rather than with the number of repositories, scanners enabled, or findings generated, it's straightforward to forecast next year's bill from this year's team size, which is not something we can say about every vendor on this list.

Trade-offs

Because Aikido orchestrates other engines rather than owning the full stack, you have less control over rule tuning than you would with Semgrep directly. You also can't always tell, from the dashboard alone, which underlying engine flagged a given issue, which matters if you want to reproduce a finding locally with the original tool's own CLI. And you're dependent on Aikido's triage logic being right. If it deprioritizes something it shouldn't have, that finding is easy to miss. For straightforward web applications, the triage logic is usually reliable enough that this is a minor concern rather than a dealbreaker.

Semgrep

Semgrep is, in our opinion, still the best static analysis engine on the market for teams willing to put in the work. The free CLI and open rule registry are genuinely excellent, and the paid Semgrep AppSec Platform, which adds SCA and secrets scanning on top, is a reasonable extension of that foundation.

What sets Semgrep apart is control. You can write custom rules in a readable, pattern-based syntax to catch violations of your own internal API conventions or organization-specific footguns, not just generic OWASP categories. That capability alone justifies the tool for engineering-heavy organizations with mature CI/CD pipelines. Findings are fast, scans run comfortably in CI on every pull request, and the signal-to-noise ratio is strong once you've disabled the handful of registry rules that don't apply to your stack.

Pricing

Semgrep's core scanning engine and open rule registry are free, so a team can get real SAST coverage running in CI without paying anything. The paid Semgrep AppSec Platform layers on SCA, secrets scanning, centralized findings triage, and deeper CI/CD integrations, priced per contributor across a tiered structure that scales up to an Enterprise plan with SSO and deployment flexibility. Because the free tier is a fully capable product on its own, teams can defer the purchase decision until they've proven out custom rules and know they need the platform features, which is unusual in this market.

Trade-offs

Semgrep's SCA and secrets modules are newer and less mature than Snyk's. And getting real value out of custom rules requires someone on the team who's willing to write and maintain them. That's an ongoing engineering cost, not a one-time setup task. If nobody owns that, you end up running default rulesets and leaving most of the tool's value on the table.

Snyk

Snyk built its reputation on Snyk Open Source (SCA) and it remains a strong choice specifically for dependency vulnerability management. Its vulnerability database and remediation advice (exact upgrade paths, not just "a fix exists") are still best-in-class. Snyk Code has improved significantly, and the IDE integrations and PR checks are polished.

Pricing

Snyk's pricing starts with a free tier that covers a limited number of tests and is a reasonable way to try Snyk Open Source on a small project. Paid plans are priced per contributor and organized by product line. Snyk Open Source, Snyk Code, Snyk Container, and Snyk IaC can each be licensed on their own or bundled together, with an Enterprise tier that adds SSO, custom roles, and dedicated support on top. That per-product structure is also where the trade-offs below come from.

Trade-offs

Where Snyk loses points, in our experience, is scope creep and cost. What starts as an SCA subscription tends to expand into Snyk Container, Snyk IaC, and Snyk Code, each addition adding to a bill that scales per contributor in ways that are hard to forecast as your team grows. If you're already deep in the Snyk ecosystem and your finance team has made peace with the cost curve, there's no urgent reason to rip it out. But we wouldn't recommend it as a first purchase for a team starting from zero today.

Recommendations

If you're choosing from scratch and don't already have a security engineer dedicated to tuning scanners, start with Aikido. It gets you real coverage fast, at a price you can predict, and the noise reduction means your developers won't tune it out after the first false-positive fatigue week.

If you have engineering capacity to invest in tooling and want the sharpest SAST engine with the most control, Semgrep is worth the extra setup time, especially if you're already writing custom lint rules or have unusual internal frameworks that generic scanners miss.

Snyk remains a defensible choice if dependency vulnerability management is your primary concern and you have the budget to let the platform grow with you. Just go in with eyes open about where the invoice ends up a year later.

None of these tools replace a threat model or a security review of your architecture. They catch known patterns, not design flaws. If you want help picking the right tool for your stack and actually getting it wired into CI without drowning your team in alerts, reach out to our team.
