Magic Stack

You can have Bitly-level features — without renting your data.
Shlink (86/100 in my 100 Open‑Source Projects series) is a self‑hosted URL shortener that does more than just shrink links: advanced analytics (geolocation + device data), custom slugs, QR code generation, multi‑domain support, REST API for automation — and all under your control.
Why I recommend it:
- Ownership: replaces paid services like Bitly/TinyURL so teams keep full data ownership and avoid subscription lock‑in.
- Deployability: Docker, CLI, and a PWA interface make it approachable even if you’re not a sysadmin.
- Practical for teams & campaigns: branded short links on your domain, automated creation via API, and bot detection to keep analytics clean.
- Open community: active updates and MIT license mean you can extend or audit it freely.
Quick use cases:- Marketing teams tracking campaign clicks by region & device.
- Agencies managing multiple client domains on one instance.
- Devs embedding short link creation into workflows with the REST API and CLI.

Want to try it fast? Spin up the Docker image, point a domain, and start testing QR + slug conventions for your next campaign. The docs and GitHub make the first run straightforward.
Have you self‑hosted a link shortener before — or are you thinking of replacing Bitly? Tell me your use case or roadblock.

82/100 — What if your social media scheduler was open-source, AI-powered, and something you could host yourself?
For my "100 Open‑Source Projects" series today: Postiz.
Why it stood out to me:
- It’s a full social‑media management platform (scheduling, team collaboration, drag‑and‑drop calendar, analytics) that connects to X, Instagram, LinkedIn, Facebook, Bluesky, Mastodon, Discord — the usual silos plus federated networks.
- Ships with AI agents for visuals and automation, so content creation isn’t just a checkbox — it’s part of the workflow.
- Designed to be self‑hosted on Node.js / PostgreSQL / Redis and uses OAuth (no secret key hoarding or scraping). That matters for privacy and compliance.
- Active community momentum — ~24k stars and commits within the last day — which signals it’s not an abandoned fork.
How I’d use it (quick playbook):- Agencies: self‑host for client data isolation, use team workflows and analytics for reporting.
- Community managers: automate reposts and visuals, but keep control of tokens via OAuth.
- Builders: fork and extend AI agents for niche automations (e.g., auto‑threading, RSS → multi‑channel posting).

One caveat: self‑hosting means ops responsibility. If you don’t want to run infra, evaluate hosted options or a hybrid deploy (Railway / cloud) first.
Would you consider replacing a proprietary tool like Buffer with an open‑source alternative? Have you tried self‑hosting a social stack? Tell me one feature you’d want to build into Postiz.

80/100 — Want your LLM to point to the exact page, table, or screenshot instead of guessing?
RAG Flow is an open-source Retrieval-Augmented Generation engine built for messy, real-world documents — PDFs, images, tables, scanned pages — and for the people who need reliable, citation-backed answers.
Why it matters:
- Deep document understanding: extracts text, layout, tables and visual elements so the model can find the “needle in the haystack.” That reduces hallucinations and saves time chasing wrong answers.
- No-code → agentic workflows: a visual drag-and-drop editor to build multi-step agents, memory, and tool use — useful for non-technical teams and rapid prototypes.
- Flexible deployment: use hosted LLM APIs or local runtimes (Ollama/Xinference) for cost, latency, or privacy control.
- Strong KB features: template-based chunking, metadata, auto-keyword/question generation, and GraphRAG to add context-aware retrieval.
- Enterprise-ready: observability, multiple embedding options, scalable stores (Elasticsearch/Infinity) and REST APIs so it can replace pricey commercial RAG/search licenses.
Quick signal: it’s actively developed and widely adopted — one of the more mature open-source RAG projects out there with a large community.
Why I included it in this series: If your company wrestles with complex docs or needs trustworthy answers from internal content, RAG Flow cuts integration overhead by combining deep doc parsing, retrieval, and agentic reasoning in one platform.
Tried it yet? What would you build with citation-backed answers — a contracts assistant, medical QA, or a research navigator? Drop your use case or questions below and I’ll highlight interesting examples in the next posts.

What if you could dump the subscription bill for GitHub Enterprise — and keep everything it does?
OneDev — #79 in my 100 Open‑Source Projects series — is an open‑source, self‑hosted DevOps platform that combines Git hosting, CI/CD, issue tracking, code review and project boards in one place.
Why I think it's worth a look:
- All‑in‑one: repository management + CI/CD + issue tracking + project management. Fewer integrations, less friction.
- Flexible pipelines: visual pipeline builder for people who hate YAML, plus YAML when you want it.
- Enterprise features without the subscription: code intelligence (regex search), AI‑assisted querying, and Kubernetes‑native scaling for teams that need performance.
- Data control: self‑host on your infra if compliance or privacy is a must.
When to consider it:- You want an integrated DevOps experience and full control of your data.
- Your team can support self‑hosting and ops overhead.
- You want a GitLab/GitHub Enterprise alternative without ongoing license costs.

When it might not fit:- Small teams with zero ops capacity or those who prefer fully managed SaaS.
- Organizations relying on ecosystem integrations that OneDev doesn't offer yet.

Curious to hear from people who self‑host their DevOps: have you tried OneDev, or are you sticking with SaaS? What drove your choice — cost, control, features, or something else?
