Should I vibe code
Scans Reddit conversations, clusters them into scored pain themes backed by real quotes, and turns the strongest into startup ideas
Reddit tells you what annoys people. It can't tell you what they'd pay to stop, and neither can your score.

Our verdict, the regret score and everything below it. Editorial and unsponsored — nobody can pay to be moved.
The honest answer
why the verdict is what it is
Of the scraping tools on this site, this is the one you should just build. There is no customer, no outbound message, no database of strangers' contact details and no schedule hammering somebody's server — it reads public threads through an API designed to be read, clusters them, and prints a list for an audience of one. Worst case you delete a folder. The honest warning is not about danger, it is about what the output is: a pain score is a number your own prompt invented, ranked over a corpus of people who felt like complaining in public, weighted by upvotes that measure entertainment rather than willingness to pay. Build it, use it as a reading list that saves you an hour of scrolling, and keep the link to every thread so that the first thing you do with a high-scoring theme is go and read three of them yourself. The failure mode is not a leak. It is spending six months on the top row of a spreadsheet.
What actually breaks
not "if". the specific failures.
- Coverage, immediately and invisibly — Reddit listing endpoints stop at roughly a thousand items per query, so "I scanned r/smallbusiness" means you scanned a recent slice of it and the tool will not say which slice
- The rate limit, at around a hundred requests a minute on a free OAuth client, which is fine for one scan and not fine for the broad mode that auto-discovers subreddits
- Clustering, which groups by topic because that is what embeddings do — you get "everybody mentions pricing" rather than "pricing is the thing that hurts", and those are different findings
- The score, which has no ground truth: nothing in the pipeline was ever checked against an outcome, so a 91 and a 63 differ only in how the summariser felt
- Quote fidelity, when the model paraphrases and you paste it as evidence — a compressed quote attached to a real username is a misattribution with a link next to it
- Deleted and removed content, cached in your store after the author took it down, which is a small thing until you publish the quote
- Selection, which is the deep one: a subreddit is people who chose to post about a problem, so the loudest pain is the one with the best community, not the biggest market
Is that you?
the verdict is a default, not a law
- It runs on your machine, for you, and the output is a document nobody else sees
- Every claim in the output carries a permalink and a fetch date, and you read the threads before believing the number
- You use the official API with your own credentials and stay inside the free tier's limits
- You treat the scores as an ordering of what to read, not as a measurement of anything
- You are turning it into a product that republishes other people's posts, at which point Reddit's data terms become a real conversation rather than a formality
- The pipeline collects usernames and profiles into anything resembling a contact list
- You plan to message the people whose complaints you mined, which converts a research tool into unsolicited outreach
- The score is going to be shown to an investor, a co-founder or a client as evidence rather than as a shortlist
If you build it anyway
the checklist, then the prompt that enforces it
- Store the permalink, the fetch timestamp and the verbatim text with every quote, and render quotes from the stored text rather than from the model's paraphrase. Evidence you cannot click is not evidence.
- Cache aggressively and scan on demand rather than on a schedule. There is no reason for this to run at 3am, and the free API tier is generous precisely because nobody is hammering it.
- Print the coverage of every scan next to the results: how many posts, over what date range, and what the listing cap cut off. A confident summary of two hundred threads reads identically to a confident summary of eight.
- Separate the counting from the writing. Compute frequency, recency and engagement as plain numbers you can inspect, and let the model name the theme — never let it produce the score, because a generated number looks exactly like a measured one.
- Re-check quotes before reuse. Posts get edited and deleted, and a cached line attributed to a live username is the one output here that can embarrass someone other than you.
- Keep a rejected pile. The themes you dismissed and why is the only record that turns this into a research habit rather than a slot machine you pull until it says something you like.
I am building a tool that reads public Reddit threads, clusters them into
themes and summarises the recurring complaints. It is for me alone. Keep it
honest rather than impressive — the failure here is believing the output.
1. Use the official Reddit API with my own OAuth credentials, and respect the
documented rate limit with real backoff. No unauthenticated scraping of
old.reddit HTML, no rotating anything.
2. Before writing the analysis, write the store: post id, permalink, subreddit,
author, created time, fetch time and verbatim body. Everything downstream
reads from this, and nothing is fetched twice.
3. Report coverage with every result — post count, date range, and where the
thousand-item listing cap truncated the query. Refuse to print a theme
summary without the sample size beside it.
4. Keep scoring numeric and inspectable: frequency, distinct authors, recency,
engagement. Do not let the model emit a 0-100 score. If I ask for one, push
back and explain that a generated number is indistinguishable from a
measured one on the page.
5. Quotes are rendered verbatim from the store with a permalink. If the model
paraphrases, label it as a paraphrase. Never attribute a rewritten sentence
to a username.
6. Cluster by embedding if you like, but show me the members of each cluster,
not just its label. I need to see when "pricing" swallowed four unrelated
conversations.
7. Run on demand. No cron, no daemon, no background scanning.
8. Do not build a contact list. No usernames outside quote attribution, no
profile crawling, no cross-referencing to other platforms.
9. Warn me in the output that the corpus is self-selected: these are people who
chose to complain in public, which is not the same population as buyers.
10. Out of scope, and say so: multi-user hosting, republishing threads, and
anything that messages the people whose posts were collected.That one keeps you out of trouble. For the prompt that actually builds it, canivibecodeit.com has one.

the boring option, and the way back out
If you want the answer this week rather than the tool. Nineteen dollars gets you scans today and a UI that is already tuned, which is a reasonable trade if the research is the point and the building is a detour. It is also a fair way to see what good output looks like before you copy the shape — subscribe for a month, read what it produces, then decide whether your version needs to exist.
$19/mo is cheaper than your weekend.
There is nothing to exit. The data is a folder of JSON with permalinks in it, the analysis is a script, and if you stop caring the whole thing costs nothing to leave sitting there. That is most of the argument for building rather than subscribing: the artefact you want is the reading list, and a reading list you own does not expire when a card does.

Questions
Three scraping tools on this site got YOUR FUNERAL. Why does this one get SHIP IT?
Because the risk in the others is never really the fetching. Apify is about operating a fleet against servers that did not consent, Browse AI is about evasion and about rows that describe people, Hexomatic is about a chain that acts on what it found. This reads a public API at a polite rate, produces a document, and stops. Nothing sends, nothing is stored about anyone you will contact, and the worst outcome is a wasted afternoon.
So why is the confidence only medium?
Because the SHIP IT holds for the personal version and evaporates for the product version. The moment it is hosted, republishes other people's posts and runs scans for strangers, you are redistributing a platform's content under terms you have not read, at a request rate that is no longer yours alone. That is a different entry, and it would not score like this one.
Is a pain score worth anything at all?
As an ordering, yes. As a measurement, no. Nothing in the pipeline was ever validated against an outcome — no cohort, no conversion, no revenue — so the number encodes how often a phrase appeared and how confident the summariser sounded. Keep it, sort by it, and never quote it to anyone. The value is that it puts twelve threads in front of you instead of four hundred.
What is the single most useful thing to add after v0?
The rejected pile. Log every theme you looked at and dismissed, with one line about why. Without it you rerun the scan every fortnight and rediscover the same four ideas, feeling slightly more convinced each time — which is exactly the failure this category of tool encourages, and the only thing that fixes it is a record of your own previous judgement.
Every week, someone ships something they shouldn’t have.
