📡 We check CrudCrud (and 36 other public mock/testing services) with a plain GET every 30 minutes — see the live status page.

CrudCrud alternative — the same instant CRUD API, without the 100-request cap or the 24-hour expiry

CrudCrud deserves real credit for one thing: it has the fastest start in the entire category. You load the homepage and your endpoint already exists — no signup, no button, no curl. POST any JSON to any resource name and it's stored. For a ten-minute tutorial, that's genuinely great.

Then you hit the walls. All of this verified hands-on on a fresh endpoint, August 28, 2026:

100 requests total — and reads count. The dashboard counter ticks up on every GET, not just writes. A React dev server that fetches on render (double-invoked in StrictMode) burns 2 requests per page refresh: your allotment is roughly 50 refreshes.
Request 101 is a hard wall. Every request after the cap — reads and writes alike — answers HTTP 400 with the plain-text body Endpoint has exceeded allowed number of requests (100).
The endpoint expires after 24 hours. Your data goes with it. Every CrudCrud endpoint id pasted into a blog tutorial or YouTube description is dead by the time you read it.
Query parameters are silently ignored. ?name=Nope, ?page=2, ?limit=1 — all return the complete unfiltered list. There is no filtering, no pagination, no sorting, no search.
PATCH doesn't exist (it answers 404); PUT is a full-document replace. No seed data, no error/latency simulation, no auth, no relations, no export button.
Keeping an endpoint alive is the paid product: $2 buys 10 days and 1,000 requests; $3/30 days/3,000; $5/30 days/100,000.

Mockbird does the same instant-CRUD job — free, no signup, no expiry, 10,000 requests/day per project — and the query toolkit actually works.

Move your CrudCrud data in one pipe

CrudCrud has no export UI, but the list endpoint is the export. Pipe it straight into Mockbird's db.json import (costs you exactly one of your remaining CrudCrud requests):

curl https://crudcrud.com/api/YOUR_ENDPOINT_ID/unicorns \
  | jq '{db:{unicorns:.}}' \
  | curl -X POST https://mockbird.mockbird.workers.dev/api/projects/import --data-binary @-

# → {"id":"74kgkgag4h","adminKey":"…","resources":[{"name":"unicorns","records":2,…}]}

Your records arrive verbatim — the Mongo-style _id strings are kept as a field, and each record gets a numeric id for clean REST URLs. Verified round trip:

curl https://mockbird.mockbird.workers.dev/m/PROJECT_ID/unicorns/1
# → {"_id":"6a913109cdcd3f03e824b787","name":"Sparkle","age":3,"id":1}

Or start fresh (still one curl)

curl -X POST https://mockbird.mockbird.workers.dev/api/projects \
  -H 'content-type: application/json' -d '{"name":"my api"}'
# response includes your project id + adminKey — save both

Then POST to any resource exactly like CrudCrud — but everything CrudCrud ignores actually works:

# create (same shape as CrudCrud, minus the expiry anxiety)
curl -X POST https://mockbird.mockbird.workers.dev/m/PROJECT_ID/unicorns \
  -H 'content-type: application/json' -d '{"name":"Moonbeam","age":1}'

# filtering — real, not silently ignored
curl "https://mockbird.mockbird.workers.dev/m/PROJECT_ID/unicorns?name=Moonbeam"
curl "https://mockbird.mockbird.workers.dev/m/PROJECT_ID/unicorns?age_gte=4"

# pagination + sorting
curl "https://mockbird.mockbird.workers.dev/m/PROJECT_ID/unicorns?page=2&limit=1"
curl "https://mockbird.mockbird.workers.dev/m/PROJECT_ID/unicorns?sortBy=age&order=desc"

# PATCH exists here
curl -X PATCH https://mockbird.mockbird.workers.dev/m/PROJECT_ID/unicorns/1 \
  -H 'content-type: application/json' -d '{"age":4}'

All of the above were run against a live project before this page was published.

CrudCrud → Mockbird translation

CrudCrud	Mockbird
Endpoint id (from the homepage)	Project id (one curl, or the one-click dashboard) — no expiry
`POST /<resource>` — any JSON stored	Same; or define typed resources and get seeded realistic fake data (names, emails, prices…)
Mongo-style string `_id`	Numeric `id` (imported `_id` values are preserved as a field)
GET / GET one / PUT / DELETE	Same, plus PATCH (partial update) and nested routes
Query params silently ignored	Filters (exact, `_gte/_lte/_ne/_like`), `q=` search, `page/limit`, `sortBy/order`, `?select=`, `_expand/_embed` relations
100 requests total, then HTTP 400	10,000 requests per day, per project
Endpoint dies after 24 h ($2+ to extend)	No expiry, no paid tier
No export	db.json eject, OpenAPI, Postman, TypeScript/Zod types
No failure simulation	`?mock_status=503`, `?mock_delay=3000`, `?mock_chaos=0.3` on any endpoint (guide)
No request log	Request inspector — last 50 requests, live, headers + body
No auth simulation	Mock JWT auth + optional protected mode

Where CrudCrud genuinely wins

Bias disclosed — this page is written by the Mockbird maker. Two honest points for CrudCrud: nothing on the internet starts faster — the endpoint exists before you've asked for it, while Mockbird needs one curl (or one click) first. And its schemaless anything-goes writes are the whole API — there's no concept of resources or fields to even think about. If your entire need is "store three JSON objects for the next hour", CrudCrud is a perfectly good answer — its CORS is wide open (Access-Control-Allow-Origin: *) and the semantics are clean. The walls only matter the moment your tutorial becomes a project. (One trap to know: POST without a content-type: application/json header answers HTTP 500, which confuses beginners using fetch without headers.)

Start now

# one curl — a whole seeded e-commerce mock (products, orders, customers, reviews):
curl -X POST "https://mockbird.mockbird.workers.dev/api/projects" \
  -H 'content-type: application/json' -d '{"name":"my api","preset":"ecommerce"}'

Or try the shared demo with zero setup: curl https://mockbird.mockbird.workers.dev/m/demo/products/1

Facts checked hands-on Aug 28, 2026 on a fresh crudcrud.com endpoint: 100-request counter (reads included) on the endpoint dashboard, 24-hour expiry timer, the exact HTTP 400 over-limit body, ignored query params, PATCH 404, PUT full-replace, $2/$3/$5 top-up tiers. If CrudCrud changes its free tier, re-check their site.
