Streaming sports APIs (WebSocket) in 2026

Providers that push live data over WebSocket, server-sent events or push feeds instead of making you poll.

How this list is built: WebSocket, SSE or push-feed delivery stated in the docs, ordered by the SportDex Score. SportDex Score explained. No provider pays to be here.

Short answer: OpenF1 (66/100), PandaScore (65/100) and SharpAPI (60/100) lead this list of 15 providers in 2026. Last checked 2026-11-04.

1. OpenF1
Free / open data
Open-source API for Formula 1 session data: lap times, car telemetry, positions, pit stops, weather, team radio and race control. Historical data from 2023 is free without auth; live access is a paid sponsorship.

66Score
What developers say
Free open-source F1 API (lap times, telemetry, positions, weather, race control) used heavily in fan dashboards, replay tools, videos and analysis posts; historical data from 2023 needs no key, live access is paid. Users note it is unofficial, lacks pre-2023 data, has had outages that forced self-hosting, and deprecates fields. FastF1 and Jolpica are common alternatives.
Liked
- + Free historical data without auth
- + Rich telemetry and race control data
Watch out
- − No data before 2023
- − Live access requires paid sponsorship

Esports data
Esports statistics and odds provider covering 13 titles such as LoL, CS, Dota 2 and Valorant, with REST API for fixtures and history plus WebSocket live feeds.
Free tierfrom €400/mo⚡ Streaming8 discussions195 GitHub repos
65Score
What developers say
Esports data provider with REST API covering LoL, CS, Dota and others. Seen in dev questions for upcoming-match apps and a few GitHub wrappers and bots. Community remarks are sparse and mostly old: one user notes odds are paywalled, and it appears as one of few usable esports APIs. No real user verdict on quality or pricing.
Liked
- + One of few dedicated esports APIs
- + Used for LoL and CS match schedules
Watch out
- − Odds data not free

60Score
What developers say
Real-time sports odds API for US sportsbooks with +EV and arbitrage endpoints, launched in 2026 with a free beta tier. Material is mostly the founder's own launch posts plus one user using it for an arb tool and praising its sharp-book coverage versus The Odds API. Repos are few; sample data, R client and MCP server exist.

4. PropLine
Odds API
Player-prop and game odds from 100+ sportsbooks and exchanges across 73 sports, with graded prop results, line history, cross-book +EV and webhook or websocket alerts. Billed per request, compatible with The Odds API format.
Free tierfrom $9/mo⚡ Streaming20 GitHub repos
59Score
What developers say
Per-request-billed player-prop and odds API that mimics The Odds API format and grades props against box scores. Digest holds only a Show HN post, directory import and the vendor's own SDK, MCP and tool repos. No independent user opinion on accuracy, limits or cost, so little is known.

What developers say
Per-event-priced odds API with props and alternate lines, mentioned by algobetting users comparing it with The Odds API and similar vendors. Reported weaknesses: inconsistent or missing Fliff odds, only main markets for Australian books, and upstream errors in one project. Several wrappers, MCP servers and dashboards build on it.
Liked
- + Props and alternate lines included
- + Considered alongside The Odds API
Watch out
- − Fliff odds inconsistent or missing

What developers say
Young odds aggregator pitched as a cheaper drop-in for The Odds API, with a free 1,000-credit tier, prediction-market books and MCP tooling. Nearly everything found is vendor-written posts, directory submissions or the founder's own repos. No independent user feedback on reliability, accuracy or support, so little is actually known.

7. Live Tennis API
Sports data API
Tennis API for ATP, WTA, Challenger and ITF with live point-by-point scores, match history, market odds, rankings and an AI win-probability field, over REST and WebSocket.

What developers say
Tennis feed (REST and WebSocket) with point-by-point scores, odds and win probability. Most mentions are vendor-authored issues and promotions. A few independent users say they use it for tennis models or a match-simulation app and find the data detailed, but there is no real feedback on price, reliability or latency.

53Score
What developers say
Odds and scores API with a free tier, offered directly and via RapidAPI. Very little real discussion: one old Stack Overflow question about a 404 and a few repos, including a sportsbook ingestion service and an odds API benchmark that lists it among rivals. No user opinion on quality or price is available.

53Score
What developers say
Aggregated odds API with broad bookmaker claims, used in side projects and sportsbook prototypes, and listed in MCP/agent tool collections. User feedback leans negative: live odds delayed by roughly 10 seconds or more, many UK bookmakers shown inactive, and Pinnacle support dropped in January 2026. Seen as an alternative to The Odds API and OpticOdds.

- + Many bookmakers and sports claimed

Little real discussion exists. Nearly all hits are the generic phrase 'all sports' or Indian resellers' promo videos. Only a couple of directory listings and a few small GitHub apps for live scores reference allsportsapi.com. Nothing is known about pricing, quality or reliability from users.

Tennis API with livescores, fixtures, odds and WebSocket, used in around thirty small GitHub projects and tutorial apps.

Odds API with broad bookmaker and sport coverage, used by developers for arbitrage tools, football research bots and benchmarks. Praised for global coverage, but users report 404/500 errors on some historical Betfair markets and limited NBA history starting late 2025, and some ask about gaps and latency. Compared with The Odds API and BoltOdds.

What developers say
Seen as the benchmark enterprise sports data supplier, used via trial keys in hobby projects, wrappers and tutorials. Developers repeatedly call it too expensive (thousands per month), opaque on pricing, sometimes unwilling to sell to small buyers, and not fast enough for live use. Common cheaper alternatives mentioned: SportsDataIO, Genius, Opta, Sportmonks.

- + Broad sport coverage and depth
- + Regarded as the reference provider

Cricket-first provider used in a number of hobby cricket and IPL score sites, with a community SDK on GitHub. The one user opinion says it covers part of what a developer wanted for deep cricket stats but not all. Other hits are vendor-style posts; nothing on pricing, reliability or support.
