Best Bluesky Posting API in 2026
Bluesky is finally where the people you actually want to follow ended up. The AT Protocol is open. The signal-to-noise is good. And it's increasingly the second platform anyone serious about distribution cross-posts to alongside Twitter/X.
If you're building anything that posts to social media, you want a Bluesky API that handles the awkward parts: app-password auth instead of OAuth, the 300-character cap, alt text for accessibility, language tags, and rate limits. I went through the major options and compared them on what actually matters for shipping.
PostPeer
PostPeer's Bluesky posting API handles the parts of the AT Protocol you don't want to deal with. You give it an app password once, then call the same /v1/posts/ endpoint you use for every other platform.
Text up to 300 characters. Image with optional alt text per attachment (which Bluesky users genuinely care about). Language tags via BCP-47 codes so the AT Protocol surfaces your post in the right feeds. Schedule for later or post now.
The API shape is identical to the rest of PostPeer. The same access key that posts to Twitter/X, Instagram, YouTube, TikTok, LinkedIn, Facebook, and Pinterest also posts to Bluesky. One SDK, one schema, one billing line.
Pricing: $8.50 per 1,000 posts on the Starter plan, dropping to $6 per 1,000 on Pro. Free tier with 20 posts. Pay-as-you-go credit packs that never expire if your volume is unpredictable.
Pros:
- Single endpoint covers Bluesky alongside every other major platform
- Free tier with no credit card
- App-password auth handled (we store it encrypted, never see your real password)
- Alt text and BCP-47 language tags supported
- Scheduling included
- Pay-as-you-go credit packs that never expire
Cons:
- Bluesky-specific niceties like reply threads and quote-posts on the roadmap
- Newer than Ayrshare, smaller community
There's also a free Bluesky post scheduler if you just want to schedule posts without writing code. Useful for kicking the tires before you wire it into your app.
Zernio (formerly Late)
Zernio rebranded from Late and supports Bluesky as part of their wide platform list. They cover 13+ networks, which is the main selling point if you need niche platforms like Reddit or Telegram alongside Bluesky.
Pricing: Build plan is $19/month for 120 posts, which works out to roughly $158 per 1,000 posts. Free tier exists with 20 posts and 2 social sets. Analytics is a separate add-on.
Pros:
- Wide platform coverage including Bluesky
- AI agent integrations (MCP, ChatGPT)
- Free tier available
Cons:
- Easily the most expensive per post in this list
- Limited social sets on lower plans
- Brand confusion from the rename
Post for Me
Post for Me supports Bluesky and leans into the developer-tool framing. Pay per post, unlimited accounts, unlimited team members, analytics included.
Pricing: $10 per 1,000 posts at the lowest tier, dropping to $7.50 per 1,000 on the 10k pack. Unlimited connected accounts.
Pros:
- Unlimited social accounts and team members
- Analytics and feed reading included
- Bring your own credentials option
Cons:
- No free tier to test before paying
- Slightly more expensive per post than PostPeer
- Newer product
Outstand
Outstand supports Bluesky on a usage-based pricing model. Five dollars a month base, then a penny per post.
Pricing: $5/month base includes 1,000 posts. Beyond that it's $0.01 per post. Roughly $15 per 1,000 once you factor in the base fee.
Pros:
- Transparent usage-based pricing
- Unlimited accounts included
- Stated 99.9% SLA, sub-200ms latency
Cons:
- No free tier
- Cost climbs at higher volume
- One pricing tier, no feature differentiation
Ayrshare
Ayrshare supports Bluesky as part of their enterprise-grade platform. Mature API, deep analytics, webhooks. If your company is paying and budget isn't the issue, they're a solid pick.
Pricing: Starts at $299/month with 10 profiles on the Launch plan. Business is $599/month for 30 profiles. Enterprise is custom.
Pros:
- Most mature platform on this list
- Strong analytics depth
- Webhooks and integrations
- Up to 5,000 profiles on Business
Cons:
- Starting price is 35x most alternatives
- No free tier
- 10 profile limit on Launch is stingy for the price

How to actually pick one
For most developers and small teams, PostPeer hits the sweet spot. Lowest cost per post here, unlimited accounts on every plan, free tier to prototype, and Bluesky uses the exact same API call shape as Twitter/X or LinkedIn. If you're already cross-posting, adding Bluesky is a ONE-line change to the platforms array.
If you need Reddit, Telegram, or Snapchat alongside Bluesky, Zernio has the broadest coverage but you'll pay significantly more per post. If you're at enterprise scale and need the most battle-tested option, Ayrshare is the safe pick, just be ready for the price tag.
For everyone else: start with the free tier and see how it goes. The free Bluesky scheduler is also a one-click way to test posting and scheduling without writing any code.
