Data Infrastructure

Spooler

Send, receive, ack. A hosted queue with leases and retries and little else

If you have been faking a job queue in Postgres, this gives you durable leases, retries and a dead-letter state over plain HTTP for £29 a month.

SIE Serverless

Pay-per-call hosting for small task models on an engine you can also self-host

You can test a reranker or OCR model on the hosted API today and move the same engine into your own cloud once the workload gets private or steady.

LokaDB

Postgres proxy that moves one tenant's rows into a database they own

When an enterprise prospect insists their data stay on their own Postgres, this answers with a connection-string change instead of a rewrite.

Fanout

Self-hosted traces, logs and metrics that you and your agents can query

A small team can keep its telemetry in plain Parquet files on its own box and still let an agent investigate incidents, without a hosted observability bill.

TypeSQL

Typed results for raw SQL in TypeScript, with no codegen or live database

Teams that prefer hand-written SQL to an ORM get compile errors for wrong columns and nullable joins, without a build step or a database in CI.

Rustable

A free desktop SQL and Redis client with no cap on open tabs

If TablePlus nags you to pay for a third tab, this MIT client covers Postgres, MySQL, SQLite and Redis on all three desktops at no cost.

Jog

Change one line in your workflow and have CI billed by the second

If continuous integration became a serious line item the month your agents started opening more pull requests than your people do, the per-minute price here is published rather than quoted.

Freehire

Job search that stays free, with a tracker and an open read API

The read API answers without a key at 600 requests a minute, so you can build on the index before deciding whether the paid tier is worth it.

Cascache

A Go read-through cache that rejects writes from outdated loads

The failure it closes — a slow database read landing after an invalidation and refilling the key with the old value until the TTL runs out — is one most teams only meet in production.

Stackdome

Git-push deploys, managed Postgres and preview stacks on clusters you own

Teams uneasy about renting their whole runtime from one PaaS get the push-to-deploy workflow back on a VPS or Kubernetes cluster they control.

Post-graph-RAG

GraphRAG on plain Postgres where newer documents retire facts from older ones

If your retrieval keeps citing last year's org chart, this keeps the graph, vectors and time-bounded facts in the Postgres you already run.

Lathe

Your app, Postgres and sign-in on one dedicated machine for a flat price

For a small product that would otherwise need Supabase, Vercel and Clerk bills, it puts the lot on one server you can reason about, with a usable free tier.

SV Premium

Price 237 infrastructure and AI services at your own usage, with sources dated

Before renewing Datadog or NS1, a founder can see in a minute what the same load would cost on the cheaper vendor, with the pricing page it came from.

Carrier-Explode

What each carrier pushes to iPhone, Pixel and Galaxy, decoded and diffable

When a phone loses hotspot or Wi-Fi Calling on one network, this shows the carrier config that caused it, build by build, instead of leaving you to guess.

Anyone building email search, e-discovery or inbox agents finally has a licence-clean, attachment-rich corpus far bigger and newer than Enron.

Unfenced

Acreage listings checked against the boundary map, not the blurb

A listing that claims it backs onto national forest is a claim nobody verifies, and here the shared edge is measured in feet against the federal parcel layer.

CandleFeed

A Binance perps order-book archive that publishes what it missed

The gap log names the exact holes — ten simultaneous three-node breaks and 32,153 lost trade IDs since June — before you build a backtest on top of them.

ChessBitBase

A chess game database that answers a query by intersecting bit sets

It is a free, public demonstration that a whole chess index can be nothing but compressed bitmaps, with a guide that walks through each encoding the author chose.

Trigora

Long-running workflows that resume from a checkpoint, not from their past

Worth a look if replay-based engines have made you version a workflow you only wanted to edit, though the SDKs are MIT while the engine doing the work is BSL until it converts to Apache.

Zizq

A job queue that is one binary and brings its own durable storage

You can change a job while it sits mid-queue instead of draining and re-enqueueing, but read the licence: the server is BSL 1.1, with no commercial production grant until 2030.

0sql

Send a metrics spec, get back governed SQL without granting warehouse access

You get Cube-style metric definitions and row-level security compiled into SQL, without giving a third party credentials to your warehouse.

Musql

Embedded Go SQL with SQLite's dialect, columnar storage and a query JIT

For Go services doing analytical reads on embedded data, it promises SQLite compatibility without cgo and with filter queries measured in microseconds.

Minigraf

A single-file graph store you can query as it stood on any past date

If you need to know both when a fact was true and when you learned it, Minigraf gives you that in a library you ship inside your app, with no server.

Graphene

Semantic layer and SQL-in-Markdown dashboards your coding agent can edit in a PR

It lets one agent change the pipeline, the metric definition and the dashboard in the same pull request, so analytics stops living in a separate BI tool.
