DEV Community: Peakd

How do you decide what's actually the best?

Peakd — Thu, 16 Jul 2026 23:16:46 +0000

The problem

Every time I need to choose something (a bank, a project management tool, a streaming service, a country to visit) I end up down the same rabbit hole.

Search engines give me sponsored results. Forum threads are 3 years old and say "it depends." Review sites feel like whoever pays more gets ranked higher. AI gives me different answers every time I ask.

There's no single place where regular people say "this is the best" and you can actually trust it.

So I built one: peakd.io

What it is

A community-powered ranking platform for everything. Products, services, companies, countries, restaurants, streaming platforms, banks, universities. All ranked by real people using a 1-10 scale.

Think of it like a community-maintained encyclopaedia of "what's actually good." Anyone can add entries, rate things, and edit pages. The community decides what's #1, not advertisers.

How it works

Rate anything 1-10 on overall quality and specific aspects (like ease of use, value for money, performance)
Rankings update live as votes come in
Companies can't pay for position. They can claim their page and get analytics, but rankings belong to the community.
Compare anything head-to-head. Pick 2-4 things and see them side by side with scores on every aspect.
Confidence scoring means one person giving a 10 doesn't make something #1. You need real volume behind it.

Why it's different

Most ranking and review sites have the same fundamental flaw: the companies being ranked have too much control over the narrative. Some charge tens of thousands a year for premium visibility. Others let businesses flag, hide, or bury negative feedback. Many only cover one niche (software, or entertainment, or hardware specs) and ignore everything else.

Peakd is built on one principle:

Rankings belong to the community, not the subjects of those rankings.

Companies can claim their page, respond to feedback, and see analytics. But they cannot move their position up by a single spot through payment. The only way to rank higher is to genuinely be rated higher by real users.

Features that make this work

Precision ratings (1-10 sliders, not stars)
Most sites give you thumbs up/down or rigid 5-star ratings. On Peakd, you rate 1-10 on a smooth slider. Overall and on individual aspects like Ease of Use, Value for Money, Performance, Customer Support. A 7 and an 8 mean different things. You can express exactly what you think.

Per-aspect breakdowns
Don't just see an overall score. See that a product scores 9/10 on performance but 4/10 on customer support. This is the detail that actually helps you decide.

Trust-weighted voting
Not all votes count equally. New accounts carry less weight. Long-standing contributors who vote consistently across many entities build trust and their votes influence rankings more. This prevents brigading, fake reviews, and manipulation.

Confidence scoring (Bayesian)
A product with one 10/10 vote doesn't outrank something with 200 votes averaging 8.5. The system requires volume behind a score before it can claim top position. This is why you might see a 9.0 ranked below an 8.6. The 8.6 has real consensus behind it.

Head-to-head comparisons (up to 4)
Pick 2-4 things and see them side by side. Scores on every aspect, pros/cons, specs, community sentiment. No more opening 6 tabs to compare alternatives.

Auto-generated "Best X" pages
Every category has a live leaderboard: "Best Project Management Tools," "Best Banks in the UK," "Best Countries for Remote Workers." These pages update in real-time as votes come in. Always current, never a static article from 2 years ago.

Community-maintained data
Anyone can edit entity pages, add information, submit new entries, suggest corrections. Edits go through community review (a dynamic number of upvotes based on community size = approved). Companies that claim their page can manage their own content directly, but can never control ratings, reviews, or ranking position.

Everything ranked, not just one niche
Dev tools, banks, countries, airlines, streaming services, universities, restaurants, crypto exchanges, skincare brands, car manufacturers. 240 categories across every industry. If people compare it, it belongs here.

Public contributor profile (or private, your choice)
Every rating and contribution builds your profile: a public track record of your domain expertise. Your trust score grows, your contributor rank climbs, and the community can see what you know about. It's your reputation as someone who helps others make better decisions. Prefer privacy? Switch to private mode and your activity is hidden from everyone.

The problems we solve

"Best X" search results are all sponsored content.
On Peakd, rankings are community-voted. Can't be bought.

Review scores feel inflated or manufactured.
Trust-weighted voting + confidence scoring prevents gaming.

Sites only cover one niche.
Peakd covers everything. 240 categories across all industries.

Forum threads are outdated and chaotic.
Live rankings that update with every vote. Always current.

No way to compare things at a glance.
Side-by-side comparisons with per-aspect scores (up to 4 at once).

Companies hide or bury negative feedback.
Nothing can be hidden. Community governs all content.

You need a purchase history to leave a rating.
Rate anything you've used. No purchase required.

For businesses

If your product or company is listed on Peakd (it probably already is, we have 13,000+ entities):

Claim your page for free. Verified badge, edit your content directly (no approval wait), "Page Rep" badge on your comments, basic analytics dashboard.
Pro plan (£99/mo, 14-day free trial). Custom CTA button with click-through tracking, voter demographics (see who rates you by profession), rank change alerts (email + in-app), products/services/offers showcase section, auto-updating embed widgets for your website.

Embed your score. Put a live "Rated 8.4/10 on Peakd" badge on your website. Updates automatically.

You cannot delete reviews, hide ratings, or influence your rank position. What you can do is respond, improve, and let the community see you're listening.

The numbers

Head-to-head comparisons on any combination (up to 4)
Auto-generated "Best X in 2026" pages for every category

Always free for users

Peakd is completely free to use. Rate, compare, submit, discuss, build your profile, follow categories, create lists. All of it. No paywall, no premium tier, no "unlock more features." You contribute your opinions and in return you get access to the collective knowledge of everyone else's ratings and rankings. The more people participate, the more accurate and useful the rankings become for everyone.

We make money from businesses (claimed pages and ads), never from users.

What you can do right now

Rate 5 things you use daily. Your bank, your phone, your project management tool, your streaming service. Takes 5 seconds each. Your vote changes the rankings immediately.
Check if the rankings feel right. Go to a category you know well. Does the #1 deserve to be #1? If not, vote and fix it.
Compare two things you're deciding between. Visit peakd.io/compare and see them side by side across every aspect.
Add something that's missing. Paste a URL and we'll try to auto-import the details, or fill in the form manually. Anyone can contribute.
Claim your company's page. If you're a founder or rep, your product is probably already listed. Claim it and start managing it.

What I'm looking for

People who'll actually use it. Not "cool idea, bookmarked." I mean people who'll go rate 5 things right now and see if the rankings feel right.

If you rate something and think "that ranking is wrong," good. Vote and fix it. That's the whole point.

I Built a Community Ranking Platform Alone. Tonight It Nearly Crashed Under 500 Users.

I Built a Community Ranking Platform Alone. Tonight It Nearly Crashed Under 500 Users.

I shipped Peakd tonight. Posted it on Hacker News at 2am. Within an hour, 500 people showed up and my server fell over.

This is the story of building a ranking platform solo for months, launching it at the worst possible time, and fixing a cascading database failure in real-time while strangers on the internet told me my site was broken.

What is Peakd?

A community-powered ranking platform for everything. Products, services, countries, universities, banks, streaming platforms — anything you'd Google "best X" for.

The idea: real people rate things 1-10, rankings are trust-weighted, and companies can never buy a higher position. Like Rotten Tomatoes meets Reddit, but for every industry.

15,000 entities. 1,700+ categories. One developer.

Why I Built It

Every "Best X in 2026" article online is SEO garbage. Written by someone who never touched the product, optimised for affiliate commissions.

G2 charges companies $30k/year to look good. Trustpilot feels like a shakedown. Versus.com only does hardware specs.

None of them answer the simple question: "What do real people actually think is best?"

So I built the answer. Community votes. Trust-weighted rankings. No pay-to-play. The data is community-maintained — like Wikipedia, anyone can suggest edits and corrections.

The Stack

Frontend: Next.js 16, TypeScript, Tailwind
Backend: Node.js, Express, PostgreSQL
Cache: Redis (this became important tonight)
Hosting: AWS Lightsail (2GB instance — this was the mistake)
CDN: Cloudflare
Data pipeline: Python workers pulling from Wikidata, Wikipedia, and official websites
Images: Lazy proxy with R2 CDN caching

What Happened at Launch

I posted on HN at 2am UK time (bad timing — Friday night US). Got 3 upvotes. Thought it flopped.

Then Cloudflare analytics showed 500 unique visitors. 76,000 requests in one hour. The site didn't "go viral" — it just got real traffic for the first time.

And it collapsed.

The Cascade

Every page load made 8+ API calls to PostgreSQL
No Redis caching on most routes (I'd only added it to 3 endpoints)
Database connection pool (30 connections) exhausted within minutes
Queries that normally take 50ms started taking 22 seconds
New requests queued behind stuck ones
Frontend SSR timed out waiting for backend
Users saw white pages, half-loaded content, or nothing at all

One HN commenter said: "I hit the back button before the page finished loading."

The Fix (Live, Under Pressure)

While people were browsing:

Restarted backend to clear the exhausted connection pool
Added Redis cache middleware to every read endpoint (30-120s TTL)
Warmed the caches by hitting every major endpoint locally
Discovered Redis had disconnected and all caching was silently failing
Restarted Redis connection, flushed stale data
Added ISR (Incremental Static Regeneration) to entity and category pages — Next.js now serves pre-built HTML instead of rendering on every request
Upgraded from 2GB to 4GB instance (snapshot → new instance → IP swap, ~10 minutes of downtime)

After the fix: 150ms response times. Load average 0.28. The site could now handle 3,000 concurrent users.

Lessons

1. Cache everything for anonymous users. If a response doesn't change per-user, it should never hit the database twice. I knew this. I just hadn't done it on 80% of my routes.

2. You can't test for production traffic locally. My dev machine handles 50ms queries fine. Under 500 concurrent users, those same queries take 20 seconds because they're all fighting for the same connection pool.

3. Launch timing matters more than launch quality. 2am Saturday UK time = Friday 9pm US East Coast. Half the audience is offline. The same post Tuesday at 3pm UK would have gotten 10x the engagement.

4. "Ship it" is correct advice. I spent months polishing. I could have spent 6 more months polishing. Instead I shipped, learned my server couldn't handle 500 users, and fixed it in 2 hours. That's worth more than any amount of local testing.

5. The product feedback was more valuable than the traffic. One commenter pointed out that aggregate scores don't tell you what's best for you. We actually have per-attribute ratings and audience filtering ("best X for developers", "best X for small teams") — but if a user can't find it on first visit, it doesn't exist. The feature is built. The discoverability isn't. I wouldn't have known that without launching.

What's Next

The site works now. Fast, cached, on a bigger server. The real question is whether anyone comes back.

I'm watching for 7-day retention. If people return to vote on more things without me asking — there's something here. If they don't — I'll know what to fix.

If you want to help shape the rankings: peakd.io. Pick a category you know well, rate a few things. Every vote makes the rankings more accurate.

Solo dev. Building in public. First real users tonight. Let's see what happens.
