"I Built tryKaro — an Auto Deal Tracker That Hunts the Lowest Prices Across Amazon, Flipkart, Myntra"

Rishi Banota — Tue, 01 Sep 2026 15:54:40 +0000

Tired of manually checking if that thing you want dropped in price?

I built tryKaro — it tracks thousands of products across Amazon, Flipkart, Myntra, and more, and finds you the absolute lowest price automatically. No more "notify me" tabs you forget about. No more FOMO at checkout.

🔗 Live: https://trykaro.pages.dev/

What it does

🔎 Scans thousands of products across major Indian marketplaces
📉 Surfaces the deepest discounts and limited-time offers
⚡ Updates automatically — you just open the page and see what's hot
🛒 Currently focused on products (more categories coming)

Why I built it

I kept missing price drops on stuff I actually wanted. The deal-finder sites are either ad-filled or outdated by the time you see them. So I built one that actually tracks and shows the real lowest price, refreshed automatically.

It's live now on Cloudflare Pages — free, fast, no signup.

👉 tryKaro — grab the best deals

If you use it and spot a killer deal (or a bug), drop it in the comments. Always shipping.

"remembrandt: Give Your Coding Agent a Memory It Never Loses (Claude Code / Cursor / Codex)"

Rishi Banota — Tue, 01 Sep 2026 10:10:19 +0000

You spend 20 minutes re-explaining your architecture to Claude Code, Cursor, or Codex. It answers, you close the terminal — and the next session it asks the same questions again.

Context is rebuilt from scratch every single time. That is the #1 complaint about coding agents: they are brilliant — and completely amnesiac.

I built remembrandt to fix this.

🔗 https://github.com/rishibanota/remembrandt

What is remembrandt

A tiny skill you drop into any agent (Claude Code, Cursor, Codex) plus a zero-dependency CLI. It maintains a lightweight, file-based memory store for your project and regenerates a MEMORY.md your agent reads at the start of every session.

Your agent finally remembers: the rationale behind that why, the footgun it hit yesterday, what shipped last week — without you repeating a word.

No cloud. No API keys. No database. Just files.

How it works in practice

$ remembrandt remember "Use uv for dependency management" --category decision --tags uv
Remembered entry #1 in 'decision'.

$ remembrandt remember "Never mutate the shared config object" --category gotcha
Remembered entry #2 in 'gotcha'.

$ remembrandt recall

It writes every decision, gotcha, and changelog to MEMORY.md — which lives in your repo and travels with the project.

Why I built it

I am a student dev. My coding agent kept forgetting things I told it five sessions ago. The friction was real and the fix is small. So I made it.

Zero dependencies — drops into any project, no install dance
File-based — plain markdown + JSON, survives anywhere git lives
Category + tag aware — recall by decision, gotcha, changelog, or any tag
Agent-native — reads itself at session start, no prompt surgery needed

Try it

pip install remembrandt      # or: pip install -e .
remembrandt init             # writes starter .remembrandt/
remembrandt remember "..." --category decision

It also works as a Claude Code / Cursor / Codex skill — copy the skill file into your project and the agent auto-loads memory.

Built by a student

I'm Rishi, third-year engineering student in Mumbai. I ship a new small tool every week. Find me on X @BanotaRish87559 or browse github.com/rishibanota.

"I Made The Floating Carpet Obby on Roblox - 130 Levels, Magic Carpets, Boombox Music & 8 Power-Ups"

Rishi Banota — Mon, 31 Aug 2026 16:16:37 +0000

A magic carpet, a boombox, a grapple hook, and 8 power-ups — welcome to The Floating Carpet Obby, my new Roblox game with 130 levels (and growing).

Play free: https://www.roblox.com/games/82713324366697/The-Floating-Carpet-Obby

What is The Floating Carpet Obby

Classic obby (obstacle course) gameplay with a twist: you get a magic carpet and a bag of power-ups. Glide, swing, speed-run, and jump through floating platforms across 130 levels — with more coming.

Power-ups you get

Boombox — play your favorite tunes while you jump
Golden Gloves — knock out obstacles in style
Grapple Hook — swing your way to victory
Skip Level — stuck? skip and keep going
Speed Coil — run faster than ever
Gravity Coil — jump higher to dodge traps
Magic Carpet — fly through levels like a pro
Classic Sword — battle your way through
Laser Gun — precision takedown of obstacles

Why 130 levels

Obby fans always want "just one more level." I designed the difficulty curve to stay fun — not rage-quit-inducing. If you get stuck, you either skip it or grab a power-up. Checkpoints save your progress.

Can you reach the top?

Play it

It is free on Roblox. Jump in: https://www.roblox.com/games/82713324366697/The-Floating-Carpet-Obby

Drop your highest reached level in the comments. I am curious who clears 130 first.

"I Made a Roblox Game: UGC Grinders - Slap, Fight Vegeta and Goku, Grind for Trillions in PP"

Rishi Banota — Mon, 31 Aug 2026 16:12:49 +0000

As a student dev who mostly builds Python tools and trading bots, I wanted to try something completely different: a game you can slap your way to the top on.

I made UGC Grinders on Roblox and just dropped a big update.

Play free: https://www.roblox.com/games/81849831148777/Free-UGC-Items

What is UGC Grinders

You start with a free slap weapon. Slap stuff, climb leaderboards, and stack up PP (Power Points) - think millions, billions, trillions.

Use that PP to upgrade to stronger slap weapons, unlock rare gear, and flex your grind. Compete with friends.

It is intentionally silly. Slap to power, power to slap harder.

What's new (the update)

Dance emotes added so you can celebrate a big slap
New combat system
Zombie Fight Place
Fight Vegeta and Goku to earn HUGE PP points

Yes, you read that right. The grind has levels.

Features

Start with a free slap weapon on spawn
Upgrade to stronger weapons with big PP boosts
Unlock rare gear and show off your grind
Earn millions, billions, even trillions of PP
Climb leaderboards and compete with friends

Why I built it

I had 6 Roblox games that never took off. This one felt different - the slap mechanic is stupidly simple but surprisingly satisfying to loop.

I am learning game design by building. The goal is one game that actually hooks people.

Play it

It is free on Roblox. Two minutes is all it takes.

Play UGC Grinders: https://www.roblox.com/games/81849831148777/Free-UGC-Items

If you slap your first point or climb the leaderboards, screenshot it and drop it in the comments. I read every comment.

Built by a student dev. Feedback equals feature requests.

Badges to chase

First Slap - landed your very first slap, grind begins
Drip Beginner - bought your first UGC shirt, pant, or mask
PP Collector - earned your first 1,000 PP, keep grinding

Current stats: 9 First Slaps ever, 12 Drip Beginners, 45 PP Collectors.

About the developer

I am Rishi, a third-year engineering student in Mumbai. I build Python tools, trading bots, web scrapers, and now Roblox games. Follow along on X at @BanotaRish87559.

"I Built BugSeer — an Offline, Explainable Bug-Risk Predictor (Your Code Never Leaves Your Machine)"

Rishi Banota — Sun, 30 Aug 2026 17:47:44 +0000

Most "AI code review" tools hand you a score and expect you to trust it. I don't. So I built BugSeer — a tool where every single point of risk traces back to named, inspectable evidence.

And it runs 100% offline. No cloud, no API keys, no telemetry. Your source code never leaves your machine.

The problem with "trust me, it's risky"

When a static analyzer says src/payment.py is a 96/100 defect risk, what do you do? You can't argue with a number. You either blindly refactor or ignore it.

BugSeer's rule is different: show the receipts.

🔥 src/payment.py   96/100 (critical)
████████████████████████████████████████
static 102  ·  git 70  ·  raw 172 pts

  ⎇ +40 High bug-fix density   [bugfix-density]
      9 of 10 commits (90%) look like bug fixes.

  ◆ +27 No error handling       [no-error-handling]
      4 I/O, network, parsing calls and zero try/catch.

  ◆ +25 Deeply nested control flow [deep-nesting]
      Max nesting 3, max block depth 7 (threshold 3).

You can push back on that. That's the entire point.

How it works (5 phases, all local)

Rule-based static analysis — parses with ast (Python) or tree-sitter (19+ langs). Flags no-error-handling, deep nesting, god-files, swallowed exceptions, etc.
Git intelligence — reads git log locally: change frequency, bug-fix density, revert history, fix-follow rate.
Learn from your bugs — bugseer train fits a model on your repo with a temporal split, so it's predictive, not circular.
Project heat map — colour-coded tree, or a React dashboard via bugseer serve.
"What if?" simulator — bugseer impact predicts what breaks if you touch a file.

The honesty guarantees (why I trust it)

A prediction you can't trust is worse than none:

Metrics are out-of-fold (5-fold CV), never training-set scores.
Probabilities clamped to 2–95% — a few dozen samples don't justify certainty.
Too little signal? It says so and falls back to rules instead of fitting noise.

Example from my own training run:

✓ Model trained
  Estimator      sklearn.GradientBoostingClassifier
  ROC AUC (5-fold)  0.7652
  Learned to look at:
    largest parameter list   █████████ 24.5%
    comment ratio            █████ 14.8%
    ownership concentration  ████ 10.0%

Try it

pip install -e ".[all]"     # or just: pip install -e .

bugseer scan .              # rank files by risk
bugseer explain src/payment.py   # full reasoning for one file
bugseer heatmap .           # colour-coded project tree
bugseer impact src/db.py    # "what if I change this?"
bugseer train .             # learn from your own bug history

Works in CI too:

- run: pip install -e ".[parsers]"
- run: bugseer scan . --fail-over 85 --ignore-tests

Why I built this

I'm a student developer (3rd-year BE IT). I kept shipping code I thought was fine and finding out otherwise weeks later. The existing tools were either cloud-locked or black boxes. BugSeer is my attempt at something I'd actually use: fast, private, and willing to explain itself.

It's open source under MIT. Stars, issues, and PRs welcome — especially if you break it. 👉 github.com/rishibanota/Bugseer
