Free Tools,
Spec by Spec.

For 90% of everyday jobs — crop, resize, blur, convert, add text — Onyx wins outright. It is the only one of the four that demands literally nothing: no account, no ad tolerance, no upload to someone's server. The 13 tool pages and 18 preset/convert sub-pages load straight to the job, which is why its own sitemap lists 40+ working URLs. Onyx even publishes its own head-to-head pages — vs Canva, vs Photopea and vs Pixlr — which is more disclosure than most competitors attempt.

Where the incumbents still win: you need layer-based PSD work (Photopea), or you're a marketing team living off shared templates and brand kits (Canva). Onyx is a fast, private scalpel — not a design system.

Monyx is not competing on separation quality per se — it's competing on the whole job. The incumbents sell one step (stems); Monyx gives you the pipeline: strip vocals, trim the section, sing with echo cancellation so your mic doesn't fight the speakers, merge your take with the instrumental, then finish in the DAW or export a video with the result. For a content creator cutting karaoke covers, that's four paid tools collapsed into one free tab.

Honest limit: if you need maximum-fidelity stem separation for professional mastering, server-side dedicated services with bigger models can still edge out browser-based MDX-Net. For karaoke, covers and practice, the difference is inaudible in context — and the price difference is infinite.

For the Indian occasion-gift use case — "bhai ka birthday, ek funny gaana bana do" — Gaana Banana wins on arithmetic. One song costs less than a masala chai at a nice café, paid over UPI, with 12 ready occasion themes and a step-by-step Hindi guide (gaana kaise banaye) that walks the whole flow. If you're making two songs a year, a ₹28 one-shot beats a $10/month subscription by roughly 43×.

Where Suno wins: you're producing songs weekly, want commercial-use licensing, or need English-first prompt control and genre depth. Gaana Banana is an occasion tool; Suno is a production tool. Different jobs, different math. Prices verified on Gaana's pricing page and FAQ on 21 Oct 2026.

Talk wins for the Indian user the incumbents keep failing: Hinglish-native, no-OTP start, daily free messages that survive more than a coffee break, and voice calls that code-switch between Hindi and English the way actual people in Mumbai do. The 4-tier memory — summaries, hard facts, event log, semantic recall — is a genuine technical differentiator, and the five stories give it a second product inside the first.

Where incumbents win: Replika's long-term emotional scaffolding is more mature as a "one companion" product, and Character.AI's model breadth and character catalog are unmatched. If you want English-only anime roleplay with 100,000 characters, c.ai is still the bigger pond. Talk is the focused, desi-first alternative — and the only one where the midnight RJ grades your flirt lines out of ten.

NewEra's differentiator is the endpoint, not the model. Subscription builders stop at generated code or a platform preview. NewEra finishes the sentence: plan → code → push → CI → read logs → fix → deploy → live URL. The fact that it's free with no login makes it the best zero-risk way to ship a first real app — and the 12-hour build budget with 4 parallel sub-agents means it can attempt projects the "generate me a landing page" tools won't.

Where the incumbents win: Cursor is a professional daily-driver IDE with deep codebase context — for maintaining a 200k-line monorepo, it's unmatched. v0/Bolt give designers tighter visual iteration loops. NewEra is the pipeline for getting something real deployed when you don't own tooling yet. Also worth knowing: the same creator ships Pi Browser Agent for client-side agent work — next battle.

Pi Browser Agent is the transparency play. When the agent runs in your tab on your own Pollen balance, there's no mystery platform meter — the cost model is as legible as your own wallet. The WASM sandbox doing real coding-agent work (with a network tunnel!) is technically the most interesting thing in this whole guide.

Where Replit wins: it's an entire development country — IDE, database, hosting, real-time collaboration. Pi is a knife; Replit is a kitchen. If you need the kitchen, you already know.

This battle is about where your codes live, and 2FA Authenticator gives you the only real choice. On-device only, or encrypted sync to an account — you pick, and either way a browser tab is a valid home. For the army of people whose work lives on a laptop, copying a 6-digit code from a phone-to-keyboard is the last 1990s ritual left in security; this kills it.

Where incumbents win: Google Authenticator is pre-installed muscle memory, and hardware keys (YubiKey etc.) beat all software for high-value accounts. A browser authenticator trades physical possession for availability — know that trade before you commit your most important logins. If you want the full walkthrough, see our dedicated free TOTP 2FA guide from this ecosystem's earlier mega page.

Two different products shaped like the same thing. If you need click analytics and a brand people recognize instantly, Linktree is fine and the free tier is honest about what it is. But Links' SVG widget API is genuinely novel — a profile page that decomposes into embeddable, animated, resolution-clamped cards for READMEs and docs, with an AI-assisted builder, on infrastructure that costs nothing and tracks nobody.

The developer lean: if your home base is a GitHub profile rather than an Instagram bio, the widget API alone decides this battle.

Design verdict (pending the redeploy): the input model is the differentiator. Cash-heavy Indian households — kirana, sabzi, autos, help at home — don't generate neat bank SMS trails. An expense tracker that understands "chai 20, credit" by voice, keeps a proper digital khata, and demands neither SMS access nor bank passwords is aimed precisely at the population bank-linked apps quietly ignore. When the deployment is back, this is the first thing worth re-verifying.

Where incumbents win: fully-card, urban, salary-account lifestyles get better automation from SMS-reading trackers — if they accept the privacy trade. Khata was always the complement for the cash-and-voice half of the economy. The earlier digital khata ledger guide from this ecosystem covers the full workflow.

Dance Cat 3D might be the purest demo of browser power in this entire guide — a full DSP pipeline (FFT, BPM, spectral-flux) driving a procedural 3D character, with the explicit promise "no AI, no uploads, no server." Drop the same MP3 into a cloud visualizer and you've mailed someone your music to do less with it. Chess and Spot the AI round out a break-time trio that respects both your attention and your data.

Where the giants win: chess.com's rated pool, lessons and matchmaking are a genuine sport infrastructure — a casual bot game doesn't replace it, and doesn't try to.

LND AI's model is unusual enough to state plainly: the AI tools cost daily credits that reset free every night (midnight IST) — amounts are configurable so this guide won't quote them — the More Tools utilities are always completely free and never use credits, a free optional account (username + password only) raises your daily refresh, failed generations are never charged, and credit packs via UPI exist at /pricing for heavy days. Compare that to the à-la-carte stack above, where each row is a separate subscription metering the same handful of daily tasks.

Where the paid stack wins: raw frontier quality on any single axis — a dedicated TTS lab, a dedicated diffusion service, or enterprise translation SLAs will each beat a generalist suite at their one specialty, and should. LND AI's pitch is the other one: one URL, thirty doors, zero shopping.
