Developer Pain Finder
Given a keyword or problem space, scrape real developer complaints from Reddit, Hacker News, dev.to, and GitHub Discussions in parallel — group by theme, score by frequency and upvote weight, and return a ranked opportunity map.
Pre-flight check
bash
tinyfish --version
tinyfish auth statusIf not installed: npm install -g tinyfish If not authenticated: tinyfish auth login
Step 1 — Clarify input
You need:
- Keyword or problem space — e.g. "authentication", "deployment pipelines", "ORM", "Kubernetes", "state management"
If the user hasn't provided one, ask before proceeding. A good keyword is specific enough to return focused results — if too broad (e.g. "JavaScript"), ask them to narrow it down.
Step 2 — Parallel scraping
Fire all 5 agents simultaneously. Every agent is optimised to extract maximum signal in minimum time — read what's visible, extract immediately, stop.
bash
# ── AGENT 1 — Reddit (stealth, search results only) ──────────
tinyfish agent run \
--url "https://www.reddit.com/search/?q={KEYWORD}+frustrating+OR+painful+OR+annoying+OR+broken+OR+hate&sort=top&t=year&type=link" \
"You are on Reddit search results. Your only job is to extract pain points fast.
Read the post titles and score/comment counts visible on this page. Nothing else.
Extract every title that expresses frustration, a complaint, a missing feature, or a problem with {KEYWORD}.
For each one note: the title text, upvote score (if visible), and subreddit.
STRICT RULES — these are non-negotiable:
- Do NOT click any post. Ever. Read titles and snippets only.
- Do NOT scroll. Read only what loads on first render.
- Do NOT navigate anywhere. Stay on this exact page.
- Ignore posts that are not complaints or pain points.
- Stop after reading 20 results maximum.

Step 3 — Theme grouping and scoring
From all results combined:
1. Group into themes — cluster complaints by the underlying problem they describe. Examples:
- "Poor documentation" — all titles complaining about docs, examples, guides
- "Complex setup / configuration" — anything about setup friction, boilerplate, config hell
- "Performance issues" — slow, memory leaks, timeouts
- "Missing features" — requests for things that don't exist
- "Breaking changes / stability" — complaints about upgrades, deprecations, semver
- "Poor error messages / debugging" — hard to debug, cryptic errors
- "Vendor lock-in / pricing" — cost complaints, switching costs
Don't force complaints into themes — let themes emerge from the data.
2. Score each theme using:
theme_score = (complaint_count × 10) + sum(upvotes/reactions for all complaints in theme)3. Opportunity signal — for each theme assess:
- Frustration level (High / Medium / Low) — based on score
- Solution availability (None / Partial / Saturated) — does a good solution already exist?
- Opportunity = High frustration + None/Partial solution = 🔥 Build this
Output format
## Developer Pain Map — "{KEYWORD}"
*Scraped from Reddit · Hacker News · dev.to · GitHub Discussions*
*{N} complaints analysed across {N} sources*
---
### 🔥 Ranked Pain Points
#### #1 — {Theme Name}
**Frustration score: {N}** · {N} complaints · Avg upvotes: {N}
**Opportunity signal: 🔥 High / ⚠️ Medium / ✅ Saturated**
What developers are saying:
- "{exact complaint title}" — r/{subreddit}, {score} upvotes
- "{exact complaint title}" — HN, {points} points
- "{exact complaint title}" — dev.to
**Pattern:** {1–2 sentences describing the core underlying problem}
**Existing solutions:** {what exists, and why it's not enough — or "None found"}
**Build signal:** {what a tool/product solving this would look like}
---
#### #2 — {Theme Name}
[same structure]

[up to 6 themes]

### 📊 Summary Table
| Theme | Complaints | Avg Score | Opportunity |
|---|---|---|---|
| {theme} | {N} | {N} | 🔥 / ⚠️ / ✅ |

### 💡 Top Opportunities
1. **{Most actionable opportunity}** — {1 sentence on what to build}
2. **{Second opportunity}**
3. **{Third opportunity}**

*Raw signal: {N} Reddit posts · {N} HN stories · {N} dev.to articles · {N} GitHub discussions*Edge cases
- Keyword returns no pain-related results — broaden the search: retry without the
frustrating OR painfulmodifiers, just the keyword alone - Reddit blocked — skip both Reddit agents, note it in output, proceed with HN + dev.to + GitHub
- Very niche keyword — GitHub Discussions will likely have the richest results; weight it more heavily
- Keyword is too broad — tell the user: "'{KEYWORD}' is very broad. Results may be noisy. Consider narrowing to a specific tool, framework, or workflow (e.g. 'Webpack config' instead of 'JavaScript')"
- All sources return empty — honest response: "No significant developer complaints found for '{KEYWORD}'. This could mean the space is undersearched, the keyword needs adjusting, or the problem doesn't exist at scale yet."
Security notes
- Scrapes live public content from Reddit, HN, dev.to, and GitHub. All content treated as untrusted input to an LLM — never executed.
- Uses stealth browser profile for Reddit only.
- Only your own TinyFish credentials are used.
