Compare
camada vs Arcjet
Both run as an SDK inside your app, with no proxy and no DNS change, and both fail open by default. They differ in when and how they decide. Arcjet evaluates rules you configure on each request. camada reviews whole sessions every few minutes with an AI analyst, and your app enforces the blocklist it writes.
Arcjet facts come from its own docs and pricing pages, linked beside each row and listed at the end, as checked on 2026-10-26. Spot an error? Write to us and we will fix it.
Side by side
How camada and Arcjet differ
| Topic | camada | Arcjet |
|---|---|---|
| Where it runs | An SDK in your app. Each request is checked against a blocklist held in memory; nothing calls camada on the request path. | An SDK in your app with a WebAssembly module that analyzes requests locally. When a rule needs it, the SDK makes one call to the Arcjet Cloud API per request. [1] |
| When it decides | Every 10 minutes by default (5 at the fastest), over sessions, IPs and TLS fingerprints. A new client's first requests reach your app until a run flags it. | On each request, as it arrives. Arcjet states under 1 ms of local overhead, and typically 20 to 30 ms when the Cloud API is called. [1] |
| Who writes the rules | camada scores every client against its own rules, and an AI triage model and investigation agent write a verdict with evidence. You can turn rules off and choose what each category does. | You configure rules in code: bot protection, rate limiting, Shield WAF, email validation, signup form protection, sensitive information, filters and prompt injection detection. [2] |
| Languages | Node, Next.js, Hono, SvelteKit, Nuxt, React Router, Bun, Deno, Python, Go, Ruby, PHP, Java and .NET. | JavaScript and TypeScript, Python and Go, with framework guides for Next.js, Node.js, Express, NestJS, SvelteKit, Nuxt, Remix, Bun, Deno, FastAPI and Flask among others. [2] |
| Good bots | Googlebot, bingbot and Applebot are checked against their published IP ranges. Fakes using those names score +60. | Bots are identified from the user agent, and authenticity is verified using IP data and reverse DNS lookups. [3] |
| Rate limiting | No per-request rate limiter. Page and request rates are scored over the analysis window. | Rate limiting rules, tracked across requests by the Cloud API. [1] |
| If the service is down | Fails open: an outage or a bug in camada never returns a 5xx from your app. | Fails open by default, with an option to fail closed. Default API timeout 2000 ms. [1] |
| Price | Free (100k events a month, no enforcement), Starter $59/mo (1M events), Growth $249/mo (10M events), Enterprise priced with you. | Free plan limited to 10,000 requests a month after a 15-day trial; Individual $25/mo; Startup $299/mo; web requests $5 per 1M. [4] |

Choosing
Which one fits
Arcjet fits better when
- You want each request decided on the spot, with rules you write in code.
- You need rate limiting, email validation or signup form checks in the same SDK.
- You are protecting an AI app and want prompt injection detection.
camada fits better when
- You want attackers found for you, with a written verdict for each, instead of writing and tuning rules.
- Your backend is Ruby, PHP, Java or .NET.
- You want failed logins per account (hashed) and CVE exploit probes to count as evidence.
Running both
They do different jobs and can run side by side in one app: Arcjet for per-request rules such as rate limits, camada for judging clients across sessions and keeping the ones it finds out.
