Show HN: Jottings; Anti-social microblog for your thoughts

2025-12-12 @ 08:32:13Points: 7Comments: 3

Every time I wanted to share something small or unfinished, I opened Twitter and lost 20 minutes to the timeline. Writing a blog post felt too heavy for those smaller, quick thoughts. I just wanted a place to write something down quickly and hit publish.

Jottings is that place. It gives you a clean microblog on a domain you own. Posts show up in simple chronological order. No likes. No followers. No feed trying to decide what matters.

What Jottings is - A microblogging platform that builds fully static microblog sites - A free subdomain (you.jottings.me) or connect your own domain on PRO plans - Markdown, tags, RSS feed, links with preview, and image uploads - An optional AI writing helper when you are stuck or lazy to fix grammar - Optimized for SEO and AI search friendly - Analytics for your sites

What it is not - Not a social network - Not an engagement funnel - Not trying to keep you on the site - Not a replacement for long-form blogging, though you can use it that way

How it works Each Jot publish triggers a static site rebuild. The site is stored in Cloudflare R2 and served directly at the edge. Custom domains go through Cloudflare SSL for SaaS. I built it to be boring, reliable (barring Cloudflare's latest issues), and cheap to run.

Pricing Free tier for a subdomain, text posts, and a lot more. USD5 per month for custom domains, images, full Markdown, and the writing helper. I priced it to be an easy yes.

Limitations - No comments (on purpose) - No native apps yet (iOS is coming) - The writing helper is helpful but not magic - I am a solo founder, so features move at human speed

I use Jottings regularly to document what I build. It has been the lowest-friction way I have found to publish anything publicly.

I would love feedback from this community. What would make this better or more useful for you?

Show HN: Sim – Apache-2.0 n8n alternative

2025-12-11 @ 17:20:11Points: 202Comments: 46

https://sim.ai/), an open-source visual editor to build agentic workflows. Repo here: https://github.com/simstudioai/sim/. Docs here: https://docs.sim.ai.

You can run Sim locally using Docker, with no execution limits or other restrictions.

We started building Sim almost a year ago after repeatedly troubleshooting why our agents failed in production. Code-first frameworks felt hard to debug because of implicit control flow, and workflow platforms added more overhead than they removed. We wanted granular control and easy observability without piecing everything together ourselves.

We launched Sim [1][2] as a drag-and-drop canvas around 6 months ago. Since then, we've added:

- 138 blocks: Slack, GitHub, Linear, Notion, Supabase, SSH, TTS, SFTP, MongoDB, S3, Pinecone, ...

- Tool calling with granular control: forced, auto

- Agent memory: conversation memory with sliding window support (by last n messages or tokens)

- Trace spans: detailed logging and observability for nested workflows and tool calling

- Native RAG: upload documents, we chunk, embed with pgvector, and expose vector search to agents

- Workflow deployment versioning with rollbacks

- MCP support, Human-in-the-loop block

- Copilot to build workflows using natural language (just shipped a new version that also acts as a superagent and can call into any of your connected services directly, not just build workflows)

Under the hood, the workflow is a DAG with concurrent execution by default. Nodes run as soon as their dependencies (upstream blocks) are satisfied. Loops (for, forEach, while, do-while) and parallel fan-out/join are also first-class primitives.

Agent blocks are pass-through to the provider. You pick your model (OpenAI, Anthropic, Gemini, Ollama, vLLM), and and we pass through prompts, tools, and response format directly to the provider API. We normalize response shapes for block interoperability, but we're not adding layers that obscure what's happening.

We're currently working on our own MCP server and the ability to deploy workflows as MCP servers. Would love to hear your thoughts and where we should take it next :)
