hyperswitch
Open source, composable payments platform | PCI compliant | SaaS and Self-host options | Enables connectivity to multiple payment, payout, fraud, vault and tokenization providers | Uplifts authorization with intelligent routing and revenue recovery | Reduce payment processing costs with cost observability | Reduces payment ops with reconciliation
Project mention: Prism: A stateless payment integration library extracted from 4 years of production | dev.to | 2026-04-16We have been living in this world for years building Juspay Hyperswitch, an open-source and composable payments platform. At some point we had integrations for 100+ connectors. The integrations worked well — but they were locked inside our orchestrator, not usable by anyone who just needed to talk to Stripe or Adyen without adopting an entire platform.

neon
Neon: Serverless Postgres. We separated storage and compute to offer autoscaling, code-like database branching, and scale to zero.
Project mention: Let's Build PlanetScale from Scratch: Infrastructure | news.ycombinator.com | 2026-07-16 -
Stand up a semantic layer that connects to your warehouse and exposes metrics over MCP. Open-source engines like Cube connect to BigQuery, Snowflake, Redshift, Databricks, PostgreSQL (including Supabase, Neon, and RDS), and DuckDB (including MotherDuck). You configure your warehouse connection in a config file or pass credentials via environment variables.
-
windmill
Open-source developer platform to power your entire infra and turn scripts into webhooks, workflows and UIs. Fastest workflow engine (13x vs Airflow). Open-source alternative to Retool and Temporal.
GitHub: github.com/windmill-labs/windmill

sqlx
🧰 The Rust SQL Toolkit. An async, pure Rust SQL crate featuring compile-time checked queries without a DSL. Supports PostgreSQL, MySQL, and SQLite. (by transact-rs)
Project mention: What ORMs have taught me: just learn SQL (2014) | news.ycombinator.com | 2026-07-04If you use Rust and like to write SQL, check out SQLx: https://github.com/transact-rs/sqlx
Or diesel-rs for ORM

risingwave
Event streaming platform for agentic AI. Continuously ingest, transform, and serve event streams in real time, at scale.
In crypto markets, these price differences, or spreads, appear and vanish in milliseconds. If your data pipeline takes five seconds to process a batch of prices, the opportunity is already gone. This post demonstrates how to use RisingWave—an open-source real-time event streaming platform—to detect arbitrage opportunities with sub-second latency using standard SQL.
-
paradedb
One Postgres for your application data, full-text search, vector retrieval, and aggregations. Home of the pg_search extension.
Project mention: “PostgreSQL resolves uniqueness through heap tuple visibility” | dev.to | 2026-07-09BM25 indexes (ParadeDB, pg_textsearch) for relevance-ranked lexical search
-
materialize
The live data layer for apps and AI agents. Create up-to-the-second views into your business, just using SQL (by MaterializeInc)
Project mention: ANN v3: 200ms p99 query latency over 100B vectors | news.ycombinator.com | 2026-01-25I agree our sample may not be representative but we try to stay focused on the current and next crop of tpuf customers. So far "CI prohibits network access during tests" just hasn't come up as a pain point for any of them, but as I mentioned in another comment [0], we're definitely keeping an open mind about introducing an offline dev experience.
At my last company an engineer spent a year implementing Bazel [0][1] only to have it ripped out after they left [2] due to the maintenance burden. You might say it was a little bit of a hassle. :)

PgDog | Founding Software Engineer | Remote & Onsite (SF) | Full time | https://pgdog.dev
PgDog is a proxy for scaling PostgreSQL, the world's most popular open source database.
Comp: 120k-250k + 1-3% equity.

readyset
Readyset is a MySQL and Postgres wire-compatible caching layer that sits in front of existing databases to speed up queries and horizontally scale read throughput. Under the hood, ReadySet caches the results of cached select statements and incrementally updates these results over time as the underlying data changes.

I recently added autocomplete to rainfrog, the terminal UI database tool I've been working on: https://github.com/achristmascarl/rainfrog
I initially made it as a lightweight, keyboard-centric alternative to dbeaver/pgadmin, and it now covers 95%+ of the database-related tasks I need to do at my job.

tokio-postgres handles this by just dispatching the "ROLLBACK" command in impl Drop and ignoring the response. https://github.com/rust-postgres/rust-postgres/blob/a7a49a90...
Is this not enough? What could go wrong? If the network connection dies or the task is cancelled, I'm assuming the database server cleans up the connection state and does a rollback automatically.

Project mention: PgDog is funded and coming to a database near you | news.ycombinator.com | 2026-06-10
I really wish they'd acknowledge the prior art and name that they've taken inspiration from - https://github.com/postgresml/pgcat
Don't pay a startup for your DB proxy, you should own that layer yourself inside of your infrastructure.

sql-studio
SQL Database Explorer [SQLite, libSQL, PostgreSQL, MySQL/MariaDB, ClickHouse, DuckDB, Microsoft SQL Server]
SQL Studio: A SQL database explorer that runs in the browser.

Thanks for the cool tool! I think it's worth mentioning SQLPage, which is another tool in similar vein, to generate UI from SQL. From my POV:
- SQLPage: more on UI building; doesn't use DuckDB
- Shaper: more on analytics/dashboard focused with PDF generation and stuff; uses DuckDB

In FOSS land, Mooncake Labs had a pretty nice looking pg_mooncake for dumping into Iceberg. It would be fun to compare these! https://github.com/Mooncake-Labs/pg_mooncake
