Discover Dragonfly - the most performant in-memory data store, engineered for extreme throughput at scale.

Depends

Buy if you run heavy Redis-scale workloads and the claimed savings survive your own benchmark.

Strong Redis-scale replacement with bold cost claims, but young vendor, thin reviews, murky CVE signals. Benchmark it, don't leap.

Feature depth4

Guess: Redis-compatible API covers typical cache workloads

Security posture3

Few recent CVEs; unaffected by Redis RCE

Pros

  • Markets itself at up to 80% lower cost than Redis¹
  • Unaffected by the critical Redis RCE found by Wiz Research⁵
  • Public case study: Sharp App cut latency³
  • G2 reviewers consistently praise the product²

Cons

  • Young, venture-funded vendor (~$24M) against Redis's entrenched ecosystem⁹
  • Multiple recent CVEs reference 'Dragonfly'; attribution to DragonflyDB partly unclear⁶
  • No dedicated public security page found⁴
  • Thin public review base; long-term reliability hard to judge²

Gotchas

  • medium'Up to 80% off Redis' is a marketing ceiling; validate savings against your own workload before switching.¹
  • mediumPublic review base is thin; support quality and long-term reliability unproven versus Redis.²
  • lowCVEs titled 'Dragonfly' may be DragonFly BSD or Alibaba's P2P tool — verify before treating as DragonflyDB issues.⁶

Best for

  • High-throughput caches at scale
  • Redis workloads with ballooning costs
  • Large session or event-stream workloads

Not for

  • Small apps — plain Redis or Valkey is simpler
  • Teams relying on niche Redis modules (parity likely partial)
  • Durable, disk-first storage needs — this is in-memory

Companies that use it

  • Sharp App³

Security

Mixed: a few recent CVEs reference 'Dragonfly' (some possibly other products); Wiz's critical Redis RCE did not affect Dragonfly.

  • CVE-2026-54341 — Dragonfly in-memory storeListed against 'Dragonfly, an in-memory data store'; details sparse in sources reviewed.⁷
  • CVE-2026-24124 — reported auth bypassTagged critical; source titles only 'Dragonfly', so confirm applicability to DragonflyDB.⁶
  • CVE-2025-59346 — SSRFDragonfly SSRF fixed in 2.1.0; check your deployed version.⁸

What users say

G2 reviewers consistently praise Dragonfly, but public review volume is small and snippets lack quotable detail.

Alternatives

Compare Dragonfly with each alternative.

Memcached

Dead-simple caching for basic key-value needs.

Full analysis

Based on ~12 public sources. High noise: many 'Dragonfly' hits are unrelated products (DragonFly BSD, Alibaba's P2P tool, strollers), so security attribution needs verification.
