keychains.dev▲177Hi HN — I’m a heavy OpenClaw user and, like many others, I’ve been thinking about how to give these new “unleashed” agents secure access to my accounts. Agents need API access to be useful. But API keys are long-lived secrets. And agents are not secure environments. So I built something for myself that quickly turned into a product: keychains.dev. The idea is simple: agents never see raw credentials. With Keychains.dev: • Agents make API calls via a drop-in replacement for curl or JavaScript’s fetch() • They use template variable names instead of embedding credentials • The request is…

Hey HN, I’m Brad, one of the creators of Superblocks and a YC alum, excited to share our internal tooling IDE. As developers ourselves, we faced the problem of building tons of internal admin UIs, backends to connect siloed data, reporting jobs, and data pipelines. For UIs we would build one-off React components. For integrations, we would have to decipher vendor docs and implement auth. Finally, for reporting jobs we had to handle failures and observability – many hours of repetitive engineering effort. So we built Superblocks, an internal tooling IDE to connect to any datasource…

Latchkey▲122Hi HN, At Imbue, we’ve been following the rapid developments in the agent landscape and noticed that the way agents interact with third-party services on users’ behalf often leaves a lot to be desired. Integrations are ad hoc, complicated, context-heavy, and either unfriendly to non-technical users or tied to a lock-in of some sort. We‘re experimenting with a command-line tool, Latchkey, that could be used by local agents targeted at non-technical users while avoiding remote intermediaries. As far as we know, this is the only existing approach at the intersection of these two goals. Core…
