Open source alternative to Notion’s new custom agents

Notion just announced custom agents 🎉 — we think that’s awesome, and we’ve been building in the same direction.

We made Rowboat, an open-source IDE for multi-agent systems. Instead of being locked into one app, you can:
• Build agents that connect to 500+ products (Gmail, Slack, GitHub, Notion, etc.)
• Add triggers and automations (like n8n but agent-powered)
• Create multi-agent workflows (agents can hand off tasks to each other)
• Self-host for free, or use our managed cloud (with free credits, no card needed)

Some demos we’ve built:
• Meeting prep assistant → auto-summarizes docs + pulls from calendar
• Customer support assistant → handles FAQs and escalates complex cases
• Reddit + Gmail assistant → scrapes threads and drafts replies

We’d love feedback from this community - especially from folks who are experimenting with Notion’s new agents. How do you see open-source + multi-tool agents fitting in?

Pure Python Cryptographic Commitment Scheme — General-Purpose, Offline-Capable, Zero Dependencies

Hello everyone, I have created a cryptographic commitment scheme that is universally applicable to any computer running python, it provides cryptographic security to any average coder just by copy and pasting the code module I curated below, it has many use cases and has never been available/accessible until now according to GPT deep search. My original intent was to create a verifiable psi experiment, then it turned into a universally applicable cryptographic commitment module code that can be used and applied by anyone at this second from the GitHub repository. Lmk what ya


ChatGPT’s denoscription:
This post introduces a minimal cryptographic commitment scheme written in pure Python. It relies exclusively on the Python standard library. No frameworks, packages, or external dependencies are required. The design goal was to make secure commitment–reveal verification universally usable, auditably simple, and deployable on any system that runs Python.

The module uses HMAC-SHA256 with domain separation and random per-instance keys. The resulting commitment string can later be verified against a revealed key and message, enabling proof-of-prior-knowledge, tamper-evident disclosures, and anonymous timestamping.

⸻

Repositories:

• Minimal module:
https://github.com/RayanOgh/Minimal-HMAC-SHA256-Commitment-Verification-Skeleton-Python-

• Extended module with logging/timestamping:
https://github.com/RayanOgh/Remote-viewing-commitment-scheme

⸻

Core Capabilities:
• HMAC-SHA256 cryptographic commitment

• Domain separation using a contextual prefix

• 32-byte key generation using os.urandom

• Deterministic, tamper-evident output

• Constant-time comparison via hmac.compare_digest

• Canonicalization option for message normalization

• Fully offline operation

• Executable in restricted environments

⸻

Applications:

1. Scientific Pre-Registration
• Commit to experimental hypotheses or outputs before public release

2. Anonymous Proof-of-Authorship
• Time-lock or hash-lock messages without revealing them until desired

3. Decentralized Accountability
• Enable individuals or groups to prove intent, statements, or evidence at a later time

4. Censorship Resistance
• Content sealed offline can be later verified despite network interference or regime suppression

5. Digital Self-Testimony
• Individuals can seal claims about future events, actions, or beliefs for later validation

6. Secure Collaborative Coordination
• Prevent cheating in decision processes that require asynchronous commitment and later reveal

7. Education in Applied Cryptography
• Teaches secure commitment schemes with no prerequisite tooling

8. Blockchain-Adjacent Use
• Works as an off-chain oracle verification mechanism or as a pre-commitment protocol

⸻

Design Philosophy:

The code does not represent innovation in algorithm design. It is a structural innovation in distribution, accessibility, and real-world usability. It converts high-trust commitment protocols into direct, deployable, offline-usable infrastructure. All functionality is transparent and auditable. Because it avoids dependency on complex libraries or hosted backends, it is portable across both privileged and under-resourced environments.

⸻

Conclusion:

This module allows anyone to generate cryptographic proofs of statements, events, or data without needing a company, a blockchain, or a third-party platform. The source code is auditable, adaptable, and already functioning. It is general-purpose digital infrastructure for public verifiability and personal integrity.

Use cases are active. Implementation is immediate. The code is already working.

How to open source?

tl;dr Can somebody point me where online I can learn how to run open source repository?

--

I have my custom built tool that I want to open source. I will continue to develop it and if somebody finds it usefull I want to develop it with them.

I've never worked in developement enviroment in a coding comapany. I've been mostly making simple custom tools for myself. I've been using git for my own version control, never with somebody.

How does it work?

I put it on git open repository.

Everyone can make pushes? And then I aprove those pushes and they become part of my code?

What if somebody puts some sneaky library? How can I review deep nested libaries? Is that commin and expected that someone will try to hack me?

What do people expect if they make pulls or pushes? How to merge conflicting pushes?

I know this is all basic git stuff, but I've never had opportunity to work with somebody (I work in construction company and code for myself making program tools for myself).

Where can I learn? I really want to share one of my tools, I think it's cool and usefull, but I need to know something atleast before I open the repository.

How people promote their OSS projects in this second quarter of the century?

I've been a FL/OSS contributor and maintainer for ages. Many years ago it was quite simple, if you had something to show, people were coming and contributing, using, or just throwing shit at your project in no time.
Then the Opensource scene start to gain a good amount of friction and we got r/opensource and r/coolgithubprojects, in the beginning it was quite amazing, a lot of positive or negative interactions, some honest criticisms, trolling were even welcomes sometimes.

Now there's a huge noise on every community of these kinds, your project can be good or shit, but often you don't know either, because even reaching the right audience is a nightmare, or at least this is my feeling.

How people do? Do they spam regularly all the internet corners till they get attention?

This is not a flame, I'm genuinely curious to understand how it works without asking to a random LLM bot 😅

Student project: looking for open-source data wiping projects to study/adapt

Hi everyone,

We’re a 6-member college team building a **secure data wiping application** as a software prototype. The requirements include:

* Cross-platform wiping (Windows, Linux, Android, including SSDs and hidden sectors).
* One-click, user-friendly GUI.
* Generating tamper-proof wipe certificates (JSON/PDF, digitally signed).
* Offline/bootable USB/ISO support.

Since many of us are beginners, we want to **study existing open-source projects** to understand:

1. **Wiping methods** – How do open-source tools securely erase drives?
2. **GUI integration** – How do they structure the GUI and engine together?
3. **Proof-of-wipe/certificates** – Are there any projects that implement some form of verifiable wipe logs or certificates?

We found tools like **DBAN, nwipe, BleachBit, and Parted Magic**, but we’re unsure:

* Which of these are most useful to study for **implementation guidance**?
* Are there smaller, beginner-friendly projects that demonstrate **secure deletion + GUI + logging/certificates**?
* Any GitHub repos, libraries, or references you recommend for a **student prototype**?

We’re not asking for code to copy — just **projects and references to learn from**, so we can design our software correctly and split tasks among our team.

Thanks a lot for any guidance! 🙏

Looking for open source project and team management software that runs locally

the most basic product im looking for is basically just a kanban board that doesn't run as a web service, although having a calendar and gant chart integrated would also be nice.

It seems like such a simple thing but everything seems to be made as a service that runs on docker and targeted at teams not single people managing projects through more traditional means.

Open Drone Spotter : a community app to log & share drone sightings

TL;DR What if there was a free, open-source “Waze for drones”?

You see or hear a drone → drop a quick pin on a shared map → people nearby get an alert. Later on,sensors could plug in to automatically validate alerts.

Why? Drones are showing up more often ( recent borders issues etc). Ukraine already has something similar, but I wonder if a citizen-driven, open version could work elsewhere.

Questions for you:
• Useful or just noise?
• Best way to start (open-source beta, small region test)?
• Anyone here curious to collaborate?

Not selling anything, just exploring if this could become a community projectg worth building.

Customer friendly (mostly FOSS) DAP hardware?

I had a shower thought this morning, and I thought I would run it by you guys and see if this already exists or is even viable. I want a customer friendly (preferably FOSS) digital audio player.

I've seen people modding iPods and that's great, I love it. But you're working with 20 year old technology. I want something that is built for today.

I want something that can handle 24bit FLAC files and every other codec out there. I want something that (mostly) does not require a soldering iron to repair or to replace parts.

I spent some time today researching MCUs, DACs, Amps and other things to see if this was possible.

But before I go off obsessing about creating this, Does anyone know if this has been done before? Would people even be interested in this?

Thanks!

I made a static site generator with a TUI!

Hey everyone,

I’m excited to share **Blogr** — a static site generator built in Rust that lets you write, edit, and deploy blogs entirely from the command line or terminal UI.

# How it works

The typical blogging workflow involves jumping between tools - write markdown, build, preview in browser, make changes, repeat. With Blogr:

1. blogr new "My Post Title"
2. Write in the TUI editor with live preview alongside your text
3. Save and quit when done
4. blogr deploy to publish

# Example

You can see it in action at blog.gokuls.in \- built with the included Minimal Retro theme.

# Installation

git clone https://github.com/bahdotsh/blogr.git
cd blogr
cargo install --path blogr-cli

# Set up a new blog
blogr init my-blog
cd my-blog

# Create a post (opens TUI editor)
blogr new "Hello World"

# Preview locally
blogr serve

# Deploy when ready
blogr deploy

# Looking for theme contributors

Right now there's just one theme (Minimal Retro), and I'd like to add more options. The theme system is straightforward - each theme provides HTML templates, CSS/JS assets, and configuration options. Themes get compiled into the binary, so once merged, they're available immediately.

If you're interested in contributing themes or have ideas for different styles, I'd appreciate the help. The current theme structure is in blogr-themes/src/minimal_retro/ if you want to see how it works.

The project is on GitHub with full documentation in the README. Happy to answer questions if you're interested in contributing or just want to try it out.

How to use code from MIT github project?

Hi, I'm building a plugin, that use parts of code from another MIT project. How I must approach this situation?
\- I don't want to fork and than `cherry pick` because i don't need sync with upstream and I don't need 90% of an upstream project
\- If i just copy I kinda lose all contributors info. Is it ok?

If losing contributors data is not ok, is there any way to obtain contributors list in necessary format? Because contributions are scattered around project and it is time consuming to determine, who have worked on specific parts of code i gonna use

What is DriveLite architecture

## Introduction

DriveLite is an open-source, self-hostable file storage system designed with privacy-first principles. Unlike traditional cloud storage, DriveLite ensures your files are encrypted end-to-end by default, so even your server cannot see your data.

At the same time, DriveLite is flexible advanced users can opt into server-trusted mode to enable features like previews, AI tagging, and semantic search.

This post explains DriveLite’s architecture and how it balances maximum privacy with optional convenience.

---
## 1. Core Principles

- Privacy by default → End-to-end encryption (E2EE) + zero-trust.
- Flexible control → Users can choose server-trusted mode for enhanced features.
- Modular architecture → Storage, backend, and AI/search services are separate and scalable.

---
## 2. How DriveLite Handles Security

### E2EE + Zero Trust (Default)

- Files are encrypted in the browser before upload.
- Server only stores ciphertext, cannot read user files.
- Protects against server compromises, rogue admins, or cloud breaches.
- Ideal for privacy-conscious users and sensitive data.
- Use on device AI models

### Server-Trusted Mode (Optional)

- Admins can opt-in for server-trusted mode per deployment
- Enables advanced features:
- File previews
- Semantic search
- AI tagging and AI-assisted file organization

---
## 3. Components Breakdown
### Frontend Web (React + Tailwind)

- Handles encryption/decryption for E2EE by default.
- Offers clear privacy vs. convenience toggle for users or admins.
- On-device ML (in case of E2EE + Zero trust)

### Backend (Go + Echo)

- Serves APIs for file upload, metadata, sharing, and search.
- Detects if server-trusted mode is enabled and handles decrypted files accordingly.

### Storage (MinIo (S3-compatible ) / File system)

- Stores encrypted blobs in default mode.
- Can store decrypted content when server-trusted mode is active.

### Database Layer (SQLite / PostgreSQL)

- Stores metadata and encryption keys securely.
- Supports pluggable backends for scalability.

### AI + Semantic Search (Python + Qdrant + gRPC)

- Only has access to file content in server-trusted mode.
- Enables semantic search, tagging, and AI features when opted-in.

---
## 4. Why This Architecture?
- Privacy-first by default → E2EE ensures maximum data security.
- Feature-flexible → Users can opt-in for richer functionality.
- Modular & Scalable → Each component can be independently maintained, scaled, or replaced.
- Clear tradeoff → Users control their own security vs. convenience balance.

---
## 5. Roadmap & Vision

- Mobile clients (Flutter)
- Collaborative features with optional server-trusted mode
- AI-assisted file management
- Community plugins and extensions

---
## Conclusion

DriveLite’s architecture is privacy-first, flexible, and future-proof. By default, your data is encrypted and zero-trust, but if you want enhanced features like previews and AI search, you can opt-in to server-trusted mode.

This approach makes DriveLite stand out in the self-hosting ecosystem, offering both security-conscious users and feature-hungry users exactly what they need.
