APIs & developer tools

Compare included quotas, restrictions and official provider documentation.

Free allowance

50 AI code reviews/month across 2 repositories; max 3 inline comments/review

Keep in mind

$0 forever, no card, up to 50 monthly PR panel reviews across 2 repositories; three default reviewers and maximum 3 inline comments. At quota exhaustion additional reviews are skipped (not auto-billed); custom panels, higher quotas and BYO OpenRouter key require paid plans.

Free allowance

MIT/Apache-2.0 local Python package and project manager with dependency resolution, lockfiles, Python version management and CLI tool installation; no license fee or per-project quota.

Keep in mind

This is local MIT/Apache-2.0 software, not a hosted Python development plan. Python packages and registries have independent terms; CI runners, private registries, cloud compute and bandwidth can cost money.

Free allowance

Free Developer tier: up to 10 GB data moved/month and 2 concurrent connector instances; no card required

Keep in mind

Developer is an ongoing free plan, not just a trial. Exceeding 10 GB/month or 2 connectors automatically starts a separate 30-day Cloud trial; after it ends, a payment method is needed to continue paid Cloud pipelines. Disable unneeded connectors to avoid subsequent charges.

Free allowance

Free personal projects: 10 monitors/heartbeats, one status page, Slack/email alerts; 3 GB logs and 3 GB traces/month retained for 3 days

Keep in mind

The $0 tier is positioned for personal projects. Also includes 100K exceptions, 5.000 session replays and 30 GB metrics allowance; longer retention, higher quotas and paid incident responder seats are separate. Do not assume the Free tier includes unlimited production monitoring or commercial-use rights.

Free allowance

GitHub Free personal accounts: 120 core-hours/month and 15 GB-month Codespaces storage

Keep in mind

Organization accounts do not receive this personal free quota. A 2-core machine consumes 2 core-hours per elapsed hour; if no payment method is on file, Codespaces usage is blocked when the free quota is exhausted instead of auto-billing. Paid overages require a payment method and budget controls.

Free allowance

Public packages are free; GitHub Free includes 500 MB private storage and 1 GB monthly transfer

Keep in mind

GitHub Free includes 500 MB private package storage and 1 GB private package transfer/month. Storage is shared with Actions artifacts; eligible public packages and current Container registry bandwidth are separately free. Above-limit private usage can be charged unless budgets/usage controls prevent it; plan reset applies to transfer.

Free allowance

10 minutes total browser execution time/day on Workers Free; 3 concurrent browser sessions/account

Keep in mind

The daily 10-minute Browser Run allowance is shared by Quick Actions and browser sessions. New browser sessions are limited to one every 20 seconds; browser timeout is 60 seconds and Quick Actions are capped at 1 request every 10 seconds. /crawl additionally permits 5 crawl jobs/day and up to 100 pages/job on Free; paid usage has separate charges.

Free allowance

5M requests/month; 1.000 API keys; unlimited APIs; 1 workspace member

Keep in mind

A billable-meter request means one API key validation OR one logged API call; using both can consume two units for the same application request. Free traffic is not hard-stopped immediately above the allowance, but the provider may request a tier upgrade for sustained overuse; its pricing FAQ says over-allowance accepted traffic is not retroactively billed. No credit card required.

Free allowance

250 API requests/month; full API catalog, CLI and MCP server

Keep in mind

Free remains $0 without a card for 250 API requests/month. Official pricing FAQ says usage above the monthly limit receives an approximately five-day upgrade grace window; requests over the limit MAY be billed after that. Do not assume an automatic hard stop; confirm actual billing enforcement with DATPAQ before production use.

Free allowance

100 requests/month per API across 20 APIs

Keep in mind

Free Basic is a hard stop at 100 requests/month per API, without a paid overage. Paid RapidAPI tiers use soft quotas and bill additional requests per call; commercial use is explicitly permitted even on Free.

Free allowance

500 API requests/month; 2 requests/second; 5 MB files; 1 API key

Keep in mind

The 500-request monthly API quota is separate from unlimited browser tools. The pricing comparison also lists limited Free AI Voice Studio usage (20 speech/transcription generations per day, 1.000 characters per take, 3 minutes per file); do not claim all audio/video features are excluded or that paid video transcription is included. API quota exhaustion returns HTTP 429; unused monthly API requests do not roll over. Commercial-use rights are unconfirmed.

Free allowance

100 screenshots/month (URL, HTML or Markdown to PNG/JPEG/WebP/PDF); 10 requests/minute, 1 render at a time

Keep in mind

Full-page captures have a lower maximum height and pixel density than paid plans. Failed renders and cache hits are not counted; paid overage is off by default.

Free local software
Free allowance

Free and open-source (MIT) command-line orchestrator for AI coding agents, repeatable workflows, and receipt-backed repository changes; unlimited local use for any number of projects.

Keep in mind

Runs locally in a terminal rather than as a hosted service: requires Node.js 20.10+, Git, and your own model provider or API key; no cloud dashboard, team plan, or hosted tier.

Free allowance

Free MIT-licensed local-first API client and CLI for HTTP/REST, GraphQL and gRPC; unlimited collection runs, 2 workspaces, 5 OpenAPI syncs/month; API testing, scripting and local Git-friendly collections.

Keep in mind

Desktop/CLI software, not a hosted API service; no cloud sync or provider-hosted usage allowance. Advanced in-app Git actions, private Git-provider integration, unlimited workspaces and premium support require paid plans. Follow MIT license notices; external API and CI infrastructure costs are separate.

Free allowance

3.000 atoms per month across the API catalog; 5 requests/second; 1 API key; 1 team member; MCP access.

Keep in mind

Atoms are not equivalent to API calls; each endpoint may consume a different amount. Traffic stops at the included quota unless upgraded or topped up; upstream API licenses and commercial rights vary, and Free has no paid-plan SLA.

Free allowance

MIT-licensed self-hosted Community Edition API development platform for HTTP, REST, GraphQL and WebSocket testing, API collections and collaboration; no vendor subscription, request or seat quota for the community software.

Keep in mind

Self-hosting requires your own application server, database, authentication setup, backups, TLS and ongoing security maintenance. Enterprise-only features (such as advanced SSO and audit logging) and hosted Cloud plans are separate; commercial use permitted under MIT license.

Free allowance

Free individual API client and core development tools, collections/environments, API specs and mock servers, native Git, manual Flows and collection runner.

Keep in mind

Designed for individuals; paid Solo/Team plans add automation, collaboration and expanded API monitoring. AI credits, mock-server usage and cloud queries have separate plan limits.
