COVERAGE

4 default. 3 SEO. 4 video. 5 extended.

Springy ships 16 platforms — and as of v0.14, every one has a native, voice-critiqued generator (plus a Carousel generator for LinkedIn/Instagram swipe decks). The default cascade still fans out one anchor essay into four text platforms — LinkedIn, X-thread, Threads, Bluesky. SEO, video, and extended tiers are opt-in by flag, so existing runs don't change.

Beta tester reading? The PLATFORM_SUPPORT.md in the repo is the canonical readiness matrix — this page mirrors it but the doc is the source of truth and includes per-platform confidence + known limitations.

● 4 default cascade 3 SEO opt-in 4 video opt-in 5 extended opt-in

Default cascade

4 platforms

Runs on `cascade --top` with no flags. Generator + API publish + critique loop wired. The four-text default.

Platform	Publish method	Auth / setup	Notes
LinkedIn	API	OAuth 2.0	150–300 words ideal
X (Twitter)	API	OAuth 2.0 PKCE	5–8 tweet thread
Bluesky	API	App password	≤300 chars/post; easiest first platform
Threads	API	Meta Graph API	Meta dev-app required

SEO opt-in (--seo)

3 platforms

Long-form generators that run only when you pass `--seo`. Medium, Dev.to, and the Substack newsletter generator (subject + body, with the long-form vulnerability gate).

Platform	Publish method	Auth / setup	Notes
Medium	API	Integration token	Long-form draft; runs with --seo
Dev.to	API	API key	Markdown + tags; runs with --seo
Substack	Browser	Browser session	Newsletter generator (subject + body, vulnerability-gated); browser publish

Video opt-in

4 platforms

The generator drafts the script, caption, title and tags. For the MP4: drop one alongside the draft, or opt into a renderer via `SPRINGY_VIDEO_RENDERER` — HeyGen (text-to-video from the script) or OpusClip (clips a source video). Opt in with `--platforms reel,tiktok,youtube,rumble`.

Platform	Publish method	Auth / setup	Notes
Instagram Reel	API + Browser	Meta + browser fallback	Script + caption generated; MP4 from your file or a renderer
TikTok	API	Content Posting API	Script + caption generated; MP4 from your file or a renderer
YouTube	API	Google OAuth	Title + description + tags + hook generated; you supply the video
Rumble	Browser	Browser session	Title + description + tags generated; needs an MP4

Extended opt-in (--platforms)

5 platforms

Native, voice-critiqued generators that publish to community + niche platforms. Kept out of the default fan-out so existing runs don't change — opt in with `--platforms reddit,discord,…`. Targeting details (subreddit, Pinterest board/image, Quora question URL) come from the draft frontmatter.

Platform	Publish method	Auth / setup	Notes
Discord	Webhook	Channel webhook URL	Community-message generator; webhook publish
Reddit	API + Browser	OAuth + RSS + Playwright fallback	Value-first post generator; subreddit per draft
Telegram	API	Bot API	Broadcast generator; channel publish
Quora	Browser	Browser session	Answer generator; question URL per draft
Pinterest	API	OAuth 2.0	Keyword pin generator; needs board + image

API-first, browser fallback when there isn't one.

Where a platform exposes a usable API, springy uses it — faster, more reliable, better error handling. Where it doesn't (Substack / Rumble / Quora / Instagram Reel), springy uses Playwright to drive a real browser session you logged into once via springy browser:login <platform>. Session cookies are stored at 0o700 under config/.browser-data/.

Beyond publishing

v0.14 closed the loop from publish back to generation — all local, no extra model spend:

Hook-performance learning. Each post's hook is classified at publish time; engagement is aggregated by formula and the winning hook styles are spliced back into the generator prompt per platform.
Evergreen recycling. springy evergreen re-surfaces proven past posts (dry-run first; --live to enqueue).
Analytics. springy report rolls up engagement, top hooks, best posting hours, the A/B variant leaderboard, and spend — or open the local dashboard with springy ui (Hooks + Evergreen pages included).
Automated engagement polling. springy engage poll collects comments for LinkedIn / Bluesky / Reddit on a schedule; reply drafting is opt-in and sending stays behind a human gate.

What's NOT shipped yet

Text-to-video as a default. The Reel/TikTok/YouTube/Rumble generators draft the script; rendering is opt-in via SPRINGY_VIDEO_RENDERER (HeyGen text-to-video, or OpusClip to clip a source video). Without it you provide the MP4. A built-in Remotion caption-deck renderer is still on the roadmap.
Carousel rendering. The Carousel generator drafts slide copy + a feed caption; turning slides into images and uploading the deck isn't wired yet (generation-only for now).
Hosted/brokered OAuth as the default. Nango broker is opt-in (SPRINGY_AUTH_BROKER=remote); most platforms still require a per-platform developer-app registration today.

Want a platform that isn't here?

Two paths, in order of how much time you want to spend:

File a platform-request issue. Include a link to the API docs, the auth model (OAuth / API key / browser only), and whether you'd want to use it yourself.
Write a plugin. Most simple text-posting platforms are 150-200 lines: a client, a setup flow, and a publisher. The plugin interface is documented, and plugins:new <name> scaffolds everything.
