THE DATABASE THAT RUNS YOUR BACKEND
A real database, running in this tab.
Pick an example below and watch every write move through it.

-Only what changed, changes.
A trade lands. The board does not get wiped and rewritten. One bot flips the one number that moved, and every view stays ready to read.

THE STACK
You have built this.
A database. Then Redis, because it was not fast enough. Then a cron job, because a dashboard needed a total. Then a queue, because a rule had to run on write. All of it connecting as one account, with one password.
You did not architect that. You accumulated it.
REPLACES
Every box is an apology.
Each system exists because the database could not do one specific thing. Here is what each one stands in for, and what takes its place.
The hot copy.
The database could not serve these rows fast enough, so now there are two of them. One is right.
The refresh.
The database could not keep a derived number current, so it is recomputed on a timer. Between runs it is wrong, and it looks fresh.
The rule, later.
The database could not run your logic when the data changed, so the logic runs afterwards, elsewhere, and hopes the data has not moved.
The one password.
The database could not tell your users apart, so everything connects as one privileged account and the code in front of it decides who may do what. Every rule lives twice, one connection can do anything, and queries get built from user input on the way through.
The code that knows.
None of the above knows about the others, so you wrote the code that does. It is the most fragile code you own, and it ships no feature.
PROOF
The network sets your speed limit.
Drag the sliders. Every statement in a round-trip architecture pays for the network again. ReifyDB pays once, for the whole transaction.
TRADITIONAL
25 ms
one round trip per statement, 5 of them
REIFYDB
5 ms
one round trip, the whole transaction
5× the network time, before the database has done any work.
USE CASES
Built for Live Application State
If your application reads it, writes it, and reasons about it on every request, that is the state ReifyDB was built for.
WORLD 1
Trading & Financial State
Positions, balances, order state. One bad write here can cost real money. ReifyDB makes sure that does not happen.
WORLD 2
Game & Simulation State
Player state, world state, simulation ticks. Everything stays consistent even when thousands of updates hit at once.
WORLD 3
Workflow & Process State
Multi-step workflows, task queues, process coordination. No more duct-taping Redis, Postgres, and a cron job together.
WORLD 4
Counters, Queues & Buffers
Counters, ring buffers, histograms, rate limiters. Built in, transactional, and ready to use. No external dependencies.
