1. Requirements

Platforms: Facebook, Instagram, X (Twitter), Bluesky, TikTok (minimum). Reddit, YouTube nice-to-have.
Media types: Reels, carousels, image posts, video posts, stories, threads, first comments, YouTube Shorts
Agent access: REST API or MCP server — agent creates posts, pulls analytics, manages content programmatically
Analytics: Ongoing post-level and account-level metrics (impressions, reach, likes, comments, shares, views, engagement)
Historical import: Pull existing posts and their metrics after connecting accounts
Accounts: 3 brands × 6 platforms = 18+ accounts. Brands: Limitless Pickleball, BookCreatorStudio, AI Expert (+ future)
Draft mode: NOT required — using own music baked into video editor
Meta app review: AVOID — must use tool's credentials, not BYOK (Bring Your Own Key)
Cost priority: Low monthly cost preferred. Build effort is free (unlimited Claude Code usage)

2. All Tools Evaluated

BulkPublish Upgrade Path

$0–$40/mo

bulkpublish.com

Aspect	Details
Platforms	14: FB, IG, X, TikTok, YT, Threads, Bluesky, Pinterest, LinkedIn, Google Business, Mastodon, Reddit, Discord, Telegram
Pricing	Free: $0 (1 ch/platform, 3 posts/day) · Pro: $14/mo (2 ch/platform, 30 posts/day) · Business: $40/mo (5 ch/platform, unlimited)
API	REST + MCP server (37 tools) + Python/Node SDKs + CLI
Post types	Most complete: carousels, reels, stories, threads, shorts, first comments, PDF carousels (LinkedIn)
Analytics	Best: Time series (day/week/month), top posts, engagement rate, per-post + account-level, explicit refresh endpoint
Historical import	Date-range queries on engagement data; posts listing filterable by date/status/channel
Meta app review?	❌ Not needed — uses their credentials
X costs	Free tier uses pay-as-you-go credits; Pro/Business include X
Rate limits	60 writes/min, 300 reads/min. Daily: Free=100, Pro=5K, Business=50K
Media limits	100MB per upload. JPEG/PNG/WebP/GIF/MP4/MOV/WebM. Per-platform limits documented.
Token refresh	Health check endpoint; may need manual reconnection
Age	~3 months old (GitHub: April 2026). Solo developer. Risk

3 months old, solo developer — highest risk of abandonment or breaking changes

Free plan nearly unusable: 100 API requests/day, 3 posts/day, 1 scheduled post

Analytics require manual refresh call before querying

OAuth flows happen in dashboard only — no API-based OAuth for end users

PostForMe Recommended

$10/mo

postforme.dev · Open source: GitHub

Aspect	Details
Platforms	9: X, IG, TikTok, YT, FB, Threads, Bluesky, LinkedIn, Pinterest
Pricing	$10/mo (1,000 posts) · unlimited accounts · no overage charges
API	REST + JS/TS/Python/Go/Ruby/Kotlin SDKs. No MCP server (build your own)
Post types	Image, video, reels, stories, carousels (IG), X threads. Missing: YouTube Shorts unclear, no first comments
Analytics	Post-level via feed endpoint: views, likes, comments, shares, saves, impressions, reach, engagement. Raw data only — no aggregation.
Historical import	✅ All posts on account regardless of how published. Pagination capped at 50/page.
Meta app review?	❌ Not needed in Quickstart mode
X costs	Absorbed in Quickstart mode
Rate limits	5 requests/sec, 40 requests/min Tight
Media limits	Undocumented — "we tailor to each platform"
Token refresh	Auto (but silent failures — no webhook for expired tokens)
Open issues	6 open on GitHub — see Gotchas section

LinkedIn and GMB OAuth broken in Quickstart mode (GitHub #187 — may be fixed, #237 — open)

limit > 50 silently returns 0 results (GitHub #206)

social_account_id filter broken — returns all org posts (GitHub #207)

OpenAPI spec bugs break auto-generated SDKs (GitHub #234)

40 req/min is very restrictive for polling-based agents

Outstand Contender

~$28/mo

outstand.so (formerly getlate.dev)

Aspect	Details
Platforms	10: X, IG, TikTok, YT, FB, Threads, Bluesky, LinkedIn, Pinterest, Google Business
Pricing	Base $19/mo (3,000 posts) + $0.50/account/month (hidden on homepage). 18 accounts = $9/mo extra = $28/mo total
API	REST + MCP server + TypeScript/Python SDKs + UI components
Post types	Feed posts, reels, carousels, stories, YouTube Shorts, first comments
Analytics	Per-post + account-level. Views, likes, comments, shares, impressions, reach, engagement. No aggregation.
Historical import	⚠️ Limited — only posts created through Outstand's API. No feed-level endpoint for all account posts.
Meta app review?	❌ Not needed in default mode (BYOK only for white-label)
X costs	Included in base price
Rate limits	1,000 req/min (terms) — marketing says "no 429s" (contradicts)
Media limits	Only Facebook documented: images 10MB, videos 4GB. Others "validated server-side."
Token refresh	Auto but fires webhook — you build re-auth flow. X refresh "unreliable at high volumes."
Age	<1 year old (founded Oct 2025). 26 versions in 8 months. Swedish company.

$0.50/account/month is hidden on homepage — adds up with many accounts

Data is ephemeral (cached <24h) — must pull and store yourself

X token refresh "unreliable at high volumes" — their own docs

No data export documented; no refunds on cancellation

Pinterest and Google Business may be on waitlist

4. Pricing Breakdown (18 accounts, ~100-300 posts/mo)

Tool	Monthly	What You Get	Per-Account Cost
PostForMe	$10	1,000 posts, unlimited accounts	$0
BulkPublish Pro	$14	30 posts/day, 2 ch/platform (12 accounts max)	~$0.78/acct
PostPeer Starter	$17	2,000 credits, unlimited accounts	$0
Outstand	~$28	3,000 posts + 18×$0.50 account fees	$0.50/acct (hidden)

Cost Scaling — What Happens When You Add Brands

Pre-revenue means you need predictable costs. Here's how each tool scales as you add niche brands (each brand = 6 platform accounts):

Brands	PostForMe	BulkPublish	Outstand	Zernio
1 brand (6 accts)	$10	$0 (free)	$22	$24
2 brands (12 accts)	$10	$14 (Pro)	$25	$36
3 brands (18 accts)	$10	$40 (Business)	$28	$54
5 brands (30 accts)	$10	$40 (Business)	$34	$96
10 brands (60 accts)	$10	$40 (Business)	$49	$246

PostForMe is the only tool where cost stays flat regardless of how many brands you add.

5. Gotcha Audit — Known Issues

BulkPublish

Only 3 months old, solo developer — highest abandonment risk

Free plan nearly unusable: 100 API requests/day, 3 posts/day

Analytics require manual refresh call (bp.analytics.refresh()) before querying

OAuth flows happen in dashboard only — no API-based OAuth

X threads require Pro/Business plan

PostForMe

LinkedIn OAuth broken in Quickstart mode (GitHub #187 — may be fixed)

GMB OAuth broken in Quickstart mode (GitHub #237 — open)

limit > 50 silently returns 0 results (GitHub #206)

social_account_id[] filter broken — returns all org posts (GitHub #207)

OpenAPI spec bugs break auto-generated SDKs (GitHub #234)

40 requests/minute rate limit — very restrictive for polling

Media upload limits undocumented

No first comment support

No Reddit support

Outstand

$0.50/account/month hidden on homepage — adds up fast

Data is ephemeral (cached <24h) — must store yourself

X token refresh "unreliable at high volumes" — their docs

Token expiry fires webhook — you build the re-auth flow

No data export; no refunds on cancellation

<1 year old, 26 versions in 8 months — frequent changes

Pinterest/GBP may be on waitlist

Media limits only documented for Facebook

Zernio

No significant gotchas found. Most mature option.

X API pass-through costs ($0.20/post with URL) — but spend caps available
Per-account pricing adds up with many accounts

6. Eliminated Tools & Why

Postiz (self-hosted)

postiz.com · Open source, 32 platforms

Eliminated because: Self-hosted requires creating your own Meta app and going through Meta's app review process (business verification, privacy policy, screencasts, weeks/months wait). Same problem for TikTok.

Mixpost (self-hosted)

mixpost.app · $269 one-time (Pro)

Eliminated because: Same Meta app review problem as Postiz. Lite edition only supports 3 platforms. Requires Laravel/PHP hosting.

PostSyncer

postsyncer.com · $29+/mo

Eliminated because: Too expensive ($29/mo minimum), no significant advantage over cheaper options.

Aidelly

aidelly.ai · $20+/mo

Eliminated because: $20/mo Launch tier has tight rate limits (60 reads + 20 writes/min). No significant advantage.

PostFast

postfa.st · €10+/mo

Eliminated because: EUR-denominated. MCP server exists (13 tools) but no significant advantage over BulkPublish at similar price.

PostPulse

post-pulse.com · $0.20/post or $5/account/mo

Eliminated because: Per-post costs add up quickly at volume. $5/account/month × 18 accounts = $90/mo.

Bundle.social

bundle.social · $100/mo (Pro)

Eliminated because: Pro tier too expensive. Free tier only 20 posts/mo. Only notable feature is post-history-import.

Publora

publora.com · $2.99/account/mo

Eliminated because: Analytics only available for LinkedIn. No other platform analytics.

7. Final Recommendation

Why PostForMe — especially for pre-revenue:

Unlimited accounts at $10/mo — add LP, BookCreatorStudio, AI Expert, future niches. Cost stays flat.
No Meta app review — Quickstart mode uses their credentials
1,000 posts/mo — covers 3 brands posting 1x/day per platform (540 posts/mo). Even 5 brands fits (900/mo).
Open source — inspect the code, work around bugs, self-host if needed
Build your own analytics — poll the feed API, store snapshots, calculate trends. More robust than any tool's built-in analytics.

Known issues & workarounds:

Bug	Impact	Workaround
limit > 50 returns 0 results	Data loss	Hard-code limit=50 in all API calls
social_account_id filter broken	Gets all org posts	Filter client-side after fetching
40 req/min rate limit	Can't poll aggressively	Use webhooks where possible, batch polling
GMB OAuth broken (Quickstart)	No Google Business	Skip GMB or use White Label mode
No first comments	Can't auto-comment	Manual or browser automation
No Reddit	Missing platform	Use browser automation for Reddit

Growth path — when to upgrade:

Stage	Tool	Cost	Why upgrade
Now (pre-revenue)	PostForMe	$10/mo	Flat rate, unlimited accounts, build analytics yourself
6+ brands or need Reddit	BulkPublish Business	$40/mo	5 channels/platform, Reddit, better analytics built-in
Revenue + need DMs/ads/demographics	Zernio	$54/mo+	280+ MCP tools, official partnerships, full suite

Contingency plan:

If PostForMe dies or the bugs become unmanageable:

Analytics data lives in your own DB — not locked to PostForMe
REST API code is swappable — same patterns across all tools
Upgrade to BulkPublish ($40/mo) or Zernio ($54/mo)
Cost of migration: ~2-4 hours of Claude Code time

8. Proposed Workflow

Content Pipeline

Create content — Agent generates captions, hashtags, selects media
Post via API — PostForMe REST API handles FB, IG, X, TikTok, YT, Bluesky, LinkedIn, Pinterest, Threads
FB Groups — Agent reads post content from PostForMe, uses browser automation skill to post to groups
Reddit — Agent uses browser automation for Reddit (PostForMe doesn't support it)
Poll analytics — Agent pulls feed metrics via API, stores in local DB
Content decisions — Agent analyzes stored data to determine what's working, optimal posting times, best-performing content types

Music Workflow (Reels)

Agent creates Reel via PostForMe API with caption/hashtags/media
Video has own music baked in (from editing app)
OR: Agent creates as scheduled post → you manually post on IG/FB to select trending audio

Analytics Storage (Build Your Own)

Poll PostForMe feed API daily (GET /v1/social-account-feeds/{id}?expand=metrics)
Store snapshots in local SQLite/JSON (timestamp, post_id, views, likes, comments, shares, saves, impressions, reach)
Agent calculates: engagement rate, top posts, posting frequency vs engagement, platform breakdown
Use data for content decisions: what to post, when, which platform
