Schedule Threads posts on autopilot
Posta is a native Threads scheduler. Publish posts, carousels (up to 10 items), and videos (up to 5 minutes) via Meta's official Threads API — alongside LinkedIn, TikTok, Instagram, YouTube, Pinterest, Facebook, X, and Bluesky.
How Threads posting works in Posta
Threads is Meta's microblogging network and uses the same developer-platform plumbing as Instagram. Posta authenticates via OAuth, requests the three Threads scopes (basic profile, content publish, insights), and posts directly via the official Threads API. No browser automation, no scraping — your scheduled posts hit Meta's servers exactly the way the Threads app does.
Because Posta uses the official API, posts you schedule appear on your profile with the same reach and ranking as posts published manually. There's no shadow penalty, no third-party watermark, and no risk of your account being flagged for automated behaviour.
Threads limits, handled cleanly
Threads has specific limits Posta enforces at compose time so you never hit a publish-time failure:
Posta validates each constraint before queueing the job, so you don't get publish-time surprises like a 503-character caption silently truncated or a 6-minute video rejected by the API.
Timeline or Reels — pick the placement
Threads supports two video placements: standard Timeline posts and Reels. Picking the right one matters for discovery — Reels surface in the dedicated tab and get separate recommendation treatment, while Timeline videos appear inline in followers' feeds. Posta exposes this choice as a simple radio toggle in the composer, so the same video can go out to Timeline today and Reels next week without re-uploading.
Cross-post from Instagram, without duplicate work
Most Threads users also post on Instagram. Posta lets you compose once and publish to both with one click: face-aware cropping generates the right aspect ratios for each platform, captions adapt to each network's limits, and the same media is uploaded only once on your machine. Threads and Instagram both speak Meta's Graph API, but each has its own quirks — Posta hides the differences so you don't need to remember which network caps captions where.
Threads scheduling FAQ
Can I schedule Threads posts with Posta?
Yes. Posta publishes directly to Threads via the official Meta API. Schedule individual posts, carousels (up to 10 items), and videos (up to 5 minutes) with full caption and hashtag handling.
How does Posta connect to my Threads account?
OAuth through Meta's developer platform. Posta requests three scopes — threads_basic for profile, threads_content_publish for publishing, threads_manage_insights for analytics — and stores the resulting access token encrypted (AES-256-GCM). You authorise the connection from your Threads account, not via a workaround.
What's the Threads character limit?
Threads allows captions up to 500 characters. Posta validates the length at compose time and shows a clear counter so you don't hit the limit at publish time.
Does Posta support Threads carousels?
Yes. Up to 10 items per carousel post. Posta uploads each item via Meta's container API, waits for them to be ready, then publishes the carousel as a single post.
Can I post Threads videos?
Yes. Videos up to 5 minutes long. Posta auto-formats your source video to Threads' supported dimensions and compresses for fast upload without visible quality loss.
How many hashtags can I use on Threads?
Posta enforces a 5-hashtag cap on Threads posts. If your caption contains more than 5, the extras are trimmed before publish so the post never gets rejected by the API.
Can I cross-post from Instagram to Threads with Posta?
Yes. Connect both accounts and pick both in the composer; Posta auto-formats once and publishes the same content to both, with each platform's aspect-ratio and caption rules respected. You can also pick Threads-specific placement — Timeline or Reels — via the platform configuration.
Is there a free Threads scheduler?
Posta's 14-day trial includes Threads scheduling at no cost, no credit card required. The same trial covers LinkedIn, TikTok, Instagram, YouTube, Pinterest, Facebook, X (Twitter), and Bluesky.
