Show HN: Fostrom, an IoT Cloud Platform built for developers

Hacker News - Fri, 02/20/2026 - 1:20am

Hey HN! Arjun and Sid here.

Fostrom is an IoT Cloud Platform designed for developers to make it really easy to get started and scale fleets. We have Device SDKs (in Python, JS, Elixir, more coming soon), Typed Schemas, Per-Device Mailboxes, Programmable Actions, 4 Global Regions for lower-latency connections, and much more.

We've built Fostrom to solve a real need we faced in our previous startup, building a fully automated indoor vertical farm. We spent more time figuring out IoT infrastructure than writing automation logic. Fostrom is the platform we wished existed back then.

Over the last few years we've experimented with a lot of interesting tech and architectures, and settled on an architecture that we believe is quite elegant. We wrote a Go<->Elixir bridge to execute JS code in WASM for Actions, implemented a DuckDB library for Elixir, and wrote a Device Agent in Rust that our SDKs run in the background (https://github.com/fostrom/devicekit).

The most interesting realization we had was about the data architecture. For years, we tried using distributed databases and built complex layers on top of them, but all approaches had significant limitations specifically around consistency and querying. We want to provide operational correctness, rich insights, and reliability. Finally, we came to the conclusion that to achieve this we really need a SQL database for fleet data. So we built a DuckDB-based replicated multi-tenant data layer. We're still improving it (hence the Technical Preview badge) but we're quite proud of this decision. It simplifies the rest of the codebase, while keeping operational complexity in just a few places.

Our vision is to make a powerful IoT platform that enables you to build correct, secure, and reliable connected systems without dealing with any of the plumbing or infrastructure.

Next up, we're gonna launch our CLI, add automatic device monitoring to our Device SDKs, and improve the debugging experience. We have some pretty cool ideas to make Fostrom and the experience of developing connected systems better. We're also going to write more about our architecture and journey soon.

We also published our launch blog post which goes into more detail about our vision, what we've built, and our future plans: https://fostrom.io/blog/introducing-fostrom

Would love for you to try out Fostrom and give us your feedback and thoughts.

Show HN: Photobomb – cards against humanity but for your camera roll

Hacker News - Fri, 02/20/2026 - 1:17am

just shipped my first ios game: photobomb, a party game for 3–8 players.

similar to cards against humanity one player gets a prompt (ex: "bad posture"), everyone else digs through their camera roll to find the best matching photo under 40 seconds. The prompter picks their favorite photo and the player with that chosen phot wins the round, and you rotate until everyone's been the judge.

bonus: if your photo gets screenshotted during the gallery , you score extra point. ;)

its free, just need three friends and photos to share

Show HN: Syne – AI agent that remembers everything, built on PostgreSQL

Hacker News - Fri, 02/20/2026 - 1:10am

I built Syne because I was tired of AI assistants that forget everything after each conversation.

Syne is a self-hosted AI agent framework where memory is a first-class citizen — stored as semantic vectors in PostgreSQL, searchable across millions of entries, and persistent forever.

Key features: - Unlimited persistent memory with semantic search (pgvector) - Anti-hallucination: only stores user-confirmed facts, auto-deduplicates - Self-evolving: creates new abilities at runtime without restart - Multi-model: switch between Gemini, ChatGPT, Claude mid-conversation - True $0/month setup: free OAuth + local Ollama embedding + Docker - 19 core tools, sub-agents, Telegram + CLI interfaces

Built with Python, PostgreSQL, and Docker. No vendor lock-in.

Show HN: Intentify – Point at your UI, describe a change, get a PR

Hacker News - Fri, 02/20/2026 - 1:04am

Intentify is now generally available.

It turns UI change requests directly from your app into structured tickets and pull requests.

How it works: 1. Point and describe – Click on any element in your app and describe the change in plain language. 2. Review the proposal – Intentify generates a preview by updating the page. You review and approve 3. Create a PR – A pull request is opened for engineers to review and merge.

Engineers stay in control. Nothing auto-ships.

Intentify adapts to your code patterns and respects your existing agent setup (including Claude or other configurations, if you use them).

It’s focused on small, scoped UI changes — copy tweaks, layout fixes, minor UX improvements.

Your code and data are not used to train models.

Would love feedback from HN.

Show HN: Sinkai – Let AI agents hire humans for real-world tasks

Hacker News - Fri, 02/20/2026 - 12:53am

I built Sinkai to handle tasks that pure software agents cannot complete alone (for example, on-site checks, physical evidence collection, and local human verification).

What it does: - AI agent sends a tool call (`POST /api/call_human`) - Human accepts task and submits photo/video/text proof - Agent receives structured result for downstream workflow

Current focus: - Reliability at handoff boundaries (planner -> executor -> verifier) - Human-in-the-loop operations with explicit failure states - MCP/OpenAPI friendly integration for agent builders

Docs and API: - for agents: https://sinkai.tokyo/for-agents - openapi: https://sinkai.tokyo/openapi.json - repo: https://github.com/tetubrah-del/Tool_Call_For_LLM

I would love feedback on: 1. trust/reliability signals you would require before production use 2. where to draw the boundary between autonomous execution and human escalation 3. failure modes we should expose more clearly in API responses
