Get Free API KeyA free generator for relevant, platform-shaped hashtag sets. Pick the platform, type a topic or brand keyword, and get back a ranked list of hashtags sized for that platform's optimal count and mix of broad-reach + niche-engagement tags. Faster than maintaining a spreadsheet of "good hashtags for my niche" and fresher than a 2022 blog post listicle.
Instagram allows up to 30 tags per post. The generator returns a balanced mix: 5-8 high-volume reach tags, 12-15 mid-tier niche tags, and 5-7 micro-niche or branded tags. Performs better than either an all-mega or all-micro strategy in practice.
TikTok's algorithm cares less about hashtag volume than specificity. The generator caps at 10 tags and skews toward niche-specific terms that signal "this is about X" cleanly to the recommendation system.
X uses hashtags as discovery cues but penalises tweets that look like hashtag soup. The generator returns short, topical tags and respects the 280-character budget so you have room for actual copy.
Most teams using SocialAPIs are pulling content data (posts, ads, marketplace listings) rather than publishing — but the customer-facing arm of those teams still has to post on Instagram and TikTok. The hashtag generator covers that side of the workflow without making you sign up for yet another marketing tool. If you need a programmatic version, see the FAQ.
You type a topic, niche, or brand keyword; the tool returns a ranked set of hashtags sized for the platform you picked (Instagram up to 30, TikTok and X up to 10). The output mixes high-volume hashtags that drive reach with mid-volume niche tags that drive engagement, so the set actually performs instead of just looking long.
The suggestions are generated from a curated topic-to-hashtag map that we maintain on our side. They're not pulled live from Instagram or TikTok in real time (those APIs don't expose a hashtag suggestion endpoint publicly anyway). The advantage: the suggestions are stable and won't disappear because of an upstream rate limit at the moment you need them.
Two things. First, the lists are platform-shaped — Instagram's 30-tag cap, TikTok's preference for fewer tags, X's character budget — so you don't have to manually trim. Second, the topic input lets you ask for hashtags specific to your niche; you won't get generic #love #instagood #photooftheday filler that adds zero reach.
Today, no — the hashtag generator is a browser tool only. If you need programmatic hashtag suggestions for an automation pipeline (n8n, Make, scheduled posts), ping support@socialapis.io with the use case. If there's demand, we'll expose it as an API endpoint under /tools/hashtags.
