Ek agent jo apna kaam dikhata hai.
io-cli ek terminal coding agent hai. io-harness uske neeche ka embeddable Rust runtime hai. Dono open source, dono aapki hi provider keys pe — aur kuch bhi chhupta nahi.

Ek runtime. Uske upar ek terminal.
Hum neeche ki bhaari layer banate hain aur free dete hain. Uske upar jo banao, wo aapka.
io-harness
on crates.ioYeh base hai. Rust ke liye embeddable agent runtime. Aap ek contract dete ho — kaam, wo workspace jise chhuna allowed hai, aur kya padha, likha, chalaya aur dial kiya ja sakta hai — aur yeh loop chalakar outcome wapas deta hai.
- Cargo.toml mein ek line: cargo add io-harness. Koi daemon, koi account, koi telemetry nahi
- OpenRouter, Anthropic aur OpenAI seedhe, plus 21 OpenAI-shaped presets — 8 unmein local runtimes
- Har step, har refusal aur har budget kharcha ek SQLite trace mein — jo aapka hai
io-cli
terminalIsi pe bana terminal agent. Har poori hui line aapke terminal ke apne scrollback mein jaati hai; upar do rows batati rehti hain ki abhi kya ho raha hai, kitna kharcha hua, aur ijaazat kya hai.
- Likhne se pehle run rukta hai aur diff dikhata hai: y, a ya n, phir Enter — wahi jahaan poocha gaya
- Posture footer pe dikhti hai, aur Shift+Tab next turn se use badal deta hai
- /resume purana session kholta hai aur wahi sawaal poochta hai jispe uska run ruka tha
01 — harness
Embeddable, hosted nahi
Crate ki tarah add karo aur usi process mein chalao. Koi binary, koi daemon, koi UI, koi account aur koi telemetry nahi — default build mein ek bhi optional dependency nahi.
02 — harness
Har step pe durable
Har poore hue step ke baad trace, budget kharcha aur ek checkpoint — sab ek hi transaction mein. Crash ke baad poora tree wahi se chalta hai: na steps dohraye jaate hain, na dobara paisa lagta hai.
03 — harness
Koi bhi provider
OpenRouter, Anthropic aur OpenAI crate ke apne HTTP+SSE client pe, kisi bhi OpenAI-shaped endpoint ke liye ek Compatible provider, 21 vendor presets, aur unke beech fallback.
04 — harness
Boundary, trace ke saath
Padhne, likhne, chalane aur network pe layered deny-first rules. Har refusal trace mein hai — us rule aur us layer ke naam ke saath jisne roka.
05 — cli
Terminal aapse nahi cheenta
Koi alternate screen nahi, koi mouse capture nahi — kisi bhi mode mein, kisi bhi flag ke peeche. Search, selection aur tmux copy-mode chalte rehte hain, aur yeh badle to ek test build fail kar deta hai.
06 — cli
Approval wahi, jahaan poochi gayi
Likhne se pehle run rukta hai aur proposed diff dikhata hai. y, a ya n chuno aur Enter se confirm karo — isliye kisi sentence ke beech ka ek letter likhne ka faisla nahi kar sakta. 'Is session ke liye' usi act ko usi target pe yaad rakhta hai.
07 — cli
Aapki key, screen pe kabhi nahi
Wizard key ko live endpoint pe verify karta hai, file 0600 pe likhta hai, aur provider ka env var pehle se set ho to key kahin likhta hi nahi.
08 — cli
Kharcha, aur nateeja
/cost paisa aur token — run, session, model aur din ke hisaab se; /stats outcomes, first-try, gate failures aur latency. Kuch bhi andaaze se nahi.
Ek repository pe durable baatcheet
use io_harness::{ApproveAll, OpenRouter, Policy, Session, Store};
let provider = OpenRouter::from_env()?;
let store = Store::open("runs.db")?;
let policy = Policy::default()
.layer("app")
.allow_read("*")
.allow_write("src/*")
.deny_read("secrets/*")
.allow_exec("cargo test*")
.deny_exec("cargo publish*");
let mut session = Session::open(&store, "/path/to/repo")?;
let turn = session
.turn("the test suite is failing; why?", &provider, &store, &policy, &ApproveAll)
.await?;

India first
Yahaan bana. Yahaan ke hisaab se price.
Zyada tar agent tooling dollars mein bikti hai aur sirf gigabit English pe test hoti hai. Hum doosre sire se shuru karte hain: Coimbatore ka student shared wifi pe, Indore ki chaar logon ki team ₹3,000 budget mein, aur Mumbai ka bank jiska code building se bahar nahi ja sakta.
01 — Rupee-native
Billing rupees mein, checkout pe UPI. Dev tool pe koi FX markup nahi.
02 — Slow net friendly
Ruka hua run resume ho jaata hai: /resume usi sawaal ka jawaab deta hai aur usi step se aage badhta hai, shuru se nahi.
03 — Indic bhi chalega
Prompt aur eval packs jo Hindi, Tamil aur code-mixed English pe tikein — abhi khule mein ban rahe hain.
04 — Data ghar pe rehta hai
Poora local chalao, ya Indian region mein self-host karo. Day one se DPDP-aware defaults.
Pricing · ₹ mein, convert karke nahi
Free koi trial nahi hai.
Apne providers jodo aur sab kuch use karo. Apache-2.0, self-host, koi seat count nahi, koi sign-up wall nahi.
- Apni keys laao — koi bhi provider, local models bhi
- Apni machine pe unlimited sessions
- Poora io-harness runtime, apne code mein embeddable
- Layered permission boundary aur har run ka SQLite trace
- GitHub Discussions pe community support
Paid plans aane pe Free kharab ho jaayega?
Nahi. Aaj jo chalta hai wo paywall ke peeche nahi jaayega. Paid plans hosting aur team features hain, runtime nahi.
io account chahiye?
Free ke liye nahi. Install karo, provider key daalo, chalao.
Model ka kharcha included hai?
Free mein aap seedha apne provider ko dete ho — hum tokens pe markup nahi lagate. Managed inference Go plan mein judta hai.
Install
Ek command, chaaron platforms pe.
Dono scripts aapki machine ke liye sahi build chunti hain, unpack karne se pehle SHA256SUMS se verify karti hain, aur aapki hi directory mein install karti hain — na administrator rights, na shell profile ya PATH mein koi badlav. Tap aur bucket isi repository mein rehte hain, isiliye brew tap aur scoop bucket add mein URL dena padta hai. crates.io pe publish nahi hai: source se banane ke liye Rust 1.95 ya upar.
Chhattis commands, chaar groups
Jo kuch aap type kar sakte ho.
Groups is baat se bane hain ki aap kya kar rahe ho, na ki harness ka kaunsa hissa jawaab deta hai — aur koi group das se upar nahi jaata. Inmein gyaarah chalti turn ke beech chal jaati hain, baaki mana kar di jaati hain: rule yeh hai ki command karti kya hai, dikhti kitni maasoom hai wo nahi.

Crate ke saath kya aata hai
Dono ke neeche wahi runtime.
io-cli, io-harness pe bana ek program hai. Yeh wo hai jo crate khud lekar aati hai — wahi boundary, wahi ledger aur wahi trace, chahe turn terminal se aaya ho, editor se ya CI job se.
Permission boundary
Layered, deny-first rules over read, write, exec and network. Every refusal is attributed to the rule and the layer.
Containment
Commands run in the host’s own sandbox backend, writing to the workspace and nowhere else, with per-host egress.
Durable runs
Trace, budget draw and checkpoint commit in one transaction after every completed step. A crash resumes the whole tree.
Budgets
Steps, wall-clock and token spend, from one ledger a whole tree shares and no child can raise.
Verification
The project’s own test command, a second model against a rubric, or no gate at all.
Composition
Nested sub-agents over a shared workspace, inherit-and-narrow — and every agent in the tree has an address.
Accounting
Token split, latency and TTFT per call; cost derived on read from a price table you own. An unpriced model makes a total a floor.
Extensibility
The Tool trait in-process, MCP over stdio and streamable HTTP, markdown skills, capability bundles and hooks.
Reach
A browser under the policy, LSP navigation, provider-executed web search, documents, images and fixed-argv git.
