Real insight from Sigmon

Supabasegrowth●●●●○ importance

Supabase reaches 100K+ stars, signals strong developer adoption

Supabase's main repository has crossed 102K stars with 12.3K forks, indicating substantial developer interest and ecosystem contribution. The 1,015 open issues suggest active maintenance but potentially stretched resources.

AI-generated from GitHub signal data

The Monday morning difference

Same intel, ten minutes instead of two hours.

The old way

Without Sigmon

  • Monday morning: 5 tabs open — GitHub, npm, HN, Reddit, job boards.
  • Manually compare star counts. Miss the trend. Repeat next week.
  • Competitor shipped a major release 3 weeks ago — you just found out.
  • They hired 12 engineers last quarter — you learned from their blog.
  • A 500-upvote Hacker News thread about your space — you missed it.

The Sigmon way

With Sigmon

  • One email Monday morning: headline · why it matters · do this week.
  • AI tells you: “They’re scaling for enterprise. Your SMB window is now.”
  • 12 hires + 5 new Go repos = pivoting to backend — you see it in real time.
  • 30-day sparklines show who’s accelerating and who’s stalling.
  • Before your sales call: open Intel, copy the brief, win the deal.

27 hand-picked signals. Zero vanity metrics.

Free APIs first. Public data only. Leading indicators that arrive BEFORE the news cycle.

SEC EDGAR Funding Filings

Form D filings hit EDGAR 3–7 days BEFORE TechCrunch or Crunchbase report a raise. Legal, deterministic, free.

Cert Transparency (subdomain leaks)

New TLS certs in CT logs reveal staging URLs weeks before product launches. Catch releases as they're being built.

YC "Who's Hiring" Threads

Every month, YC competitors post their hiring needs on HN. Their role mix tells you their 6-month strategy.

GitHub PR/Issue Velocity

Same stars, different teams — velocity reveals which competitors are shipping fast vs coasting.

Discord Community Size

Real-time member count from public Discord widgets — mindshare proxy that often leads npm adoption.

Wayback Machine History

1-year-back snapshots of pricing pages and homepages — strategy evolution traced retroactively.

OSSF Scorecard

Google-backed automated security & maintenance scoring. Reveals when a popular OSS competitor has terrible code-hygiene under the hood.

Bundle Size (bundlephobia)

Head-to-head JS bundle diff. "Their SDK 142 KB, yours 18 KB" — direct sales-call ammunition.

Show HN Launches

Every Show HN by a competitor is an explicit launch event. Captures the moment they ship in front of the most-engaged dev audience.

README Positioning Shifts

We diff the competitor's GitHub README headline every cycle. "Fastest serverless DB" → "AI-native database" = strategic pivot detected before the marketing site catches up.

GitHub Stars & Releases

Star trends, fork counts, releases with full changelog bodies, contributor activity.

npm Downloads

Weekly download trends, week-over-week deltas, quality scores, dependency graph.

Hacker News & Reddit

Mentions, top-story scores, subreddit growth, community sentiment across both platforms.

ecosyste.ms Cross-Registry Adoption

Dependents across npm, PyPI, crates & more — plus archive flags. Real adoption breadth, not one registry's vanity number.

Job Postings (Greenhouse / Lever)

Open roles categorized by department — leading indicator of strategy direction 6-9 months ahead.

Website Monitoring

Sitemap diffs, changelog updates, pricing page changes, WHOIS — the AI flags every meaningful move.

Product Hunt Launches

Launches, upvotes, hunter signals — catches go-to-market pushes the moment they go live.

CNCF Landscape

Cloud-native ecosystem membership + tier promotions — a credibility signal enterprise buyers weigh, tracked the moment it shifts.

Snyk Advisor Scores

Popularity, maintenance, security scores per npm package — direct sales ammunition against competitors with stale or insecure SDKs. Pro.

Recent CVE Advisories (OSV)

Last-90-days vulnerability count from Google's OSV.dev. "Their SDK shipped 3 critical CVEs this quarter" — enterprise procurement gold. Pro.

GitHub Discussions

Community Q&A volume + maintainer answer rate. Stars don't show whether a project is being maintained — discussions do.

Status Page Incidents

Major outages, MTTR, downtime patterns — sales-call gold against competitors that ship unreliably. Pro.

VS Code & JetBrains Marketplaces

Extension installs + plugin downloads — leading dev-adoption signal the registries miss entirely. Pro.

Cloudflare Radar Traffic Trend

Bucketed domain-rank trend — a free traffic-momentum proxy, no SimilarWeb subscription required. Pro.

AI Synthesis

Connects the dots across all signals. Tells you what it MEANS — strategic implication, not data dump.

Good morning

6 competitors · 27 sources

Morning Brief10 insights · Today

Hono’s npm installs (44.8M/week) just overtook Next.js (37.9M) — despite a quarter of the GitHub stars. Edge-first frameworks are winning real adoption faster than star counts suggest.

Action: Track the tools over-indexing on installs vs stars — that gap is where adoption moves before the narrative catches up.

Next.js★ leader

140K stars · 37.9M npm/wk

Still the mindshare leader of the category

Why it holds up

The case for Sigmon, without the hype

27 sources, one read

SEC EDGAR, Certificate Transparency, GitHub velocity, npm, YC hiring threads, Discord, OSSF — the kind of breadth no founder checks by hand. We watch all of it every morning so you don't open a single tab.

Leading indicators, not headlines

Form D filings land 3–7 days before TechCrunch. README pivots show before the marketing site. Staging subdomains appear weeks before a launch. You hear about moves while there's still time to react.

The category, at a founder price

Competitive intelligence is what enterprise sales teams pay tens of thousands a year for. Sigmon brings the same signal-to-strategy pipeline to a solo founder's budget.

Why Twitter/X only in Pro?▾

Twitter/X signals require real-time mentions search and account monitoring. We integrated getxapi.com for reliable account metrics and competitive mentions — this API layer is included in Pro. We also doubled down on 27 leading-indicator sources (SEC EDGAR, CT logs, YC hiring threads, Discord, Cert Transparency, README diffs, Twitter mentions, Snyk + OSV vulnerability data, ecosyste.ms cross-registry dependents, CNCF Landscape tier, VS Code + JetBrains marketplace installs, Cloudflare Radar domain rank) that fire BEFORE the news cycle. Every source's live status is visible in Settings → Sources Health — no pretending.

Will the AI actually help, or is it filler?▾

The Strategic Brief is structured (headline / why it matters for YOUR product / specific actions with dates). We inject your last 5 insights for trend continuity and your win/loss history so objection handlers are sharp. If the AI is uncertain, it says so. No hedging filler.

Can I cancel anytime?▾

Yes. No annual lock-in. Cancel from Settings, no email-to-cancel nonsense. Your data exports as CSV.

What about my own data?▾

Stays in Supabase Postgres, encrypted at rest. We don't train models on your insights. Your competitor data is yours — not aggregated, not sold, not shared.

Why we built Sigmon

Tracking competitors across GitHub, npm, Hacker News, job boards, SEC filings, and a dozen other corners of the internet is a part-time job no founder actually has time for. So the signals that matter get missed — until a competitor's move is already public.

We built Sigmon to do that watching automatically, and to surface only what changes your next move — not a data dump, just the few things worth knowing before Monday.
