Watch for

Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Payments & pricing Olostep +40

BrowserAct 25

No x402, MPP or L402 (0). Plan prices and credit costs per bot build, run and workflow step are public, but there is no direct per-call price (15). A free plan with 200 credits; whether it needs a card isn't stated (10). A person signs up and creates the key in the dashboard (0). 0 + 15 + 10 + 0 = 25.

Olostep 65

x402 documented on POST /v1/scrapes and /v1/maps at $0.01, /v1/answers at $0.05 and /v1/crawls at a dynamic price, USDC on Base through the Orthogonal facilitator, but not on batches or search. Our unpaid POST on 30 September got a 402 with an empty body and no payment requirements, so a stock client had nothing to sign (15 of 40). Plans, per-operation credit costs and credit packs from $20 for 10,000 are public (20). Trial of 500 successful requests with no card (20). The x402 route would let an agent start without signup, but it didn't return a price in our probe (10 of 20).

Agent ergonomics Olostep +38

BrowserAct 49

Graded on the API, since the MCP tool list isn't published. Task results come back whole, with no field selection found (10). Lists of bots, templates and tasks are paginated (15). Errors carry numeric codes with documented meanings for a few cases (12). No idempotency key on task creation; webhooks and a status endpoint avoid polling loops (5). No official SDK in two languages; the CLI is Python (7). 10 + 15 + 12 + 5 + 7 = 49.

Olostep 87

11 MCP tools, and the API lets you choose formats and page results (20 of 25). Cursor pagination and items_limit on crawl and batch results, and batches of up to 100,000 URLs (20). Structured error objects with a code an agent can branch on (17 of 20). All 11 MCP tools carry readOnlyHint, destructiveHint and idempotentHint, with the two job creators marked non-idempotent, and no idempotency keys on the API (15 of 20). Python and Node SDKs and a CLI, one required field on a scrape (15).

Reliability Olostep +37

BrowserAct 23

Hosted reading. No status page found (0) and no readable incident history (5). The docs say there are no rate limits, and give concurrency by plan (2 free, up to 20 for paid API users) and a 7-hour task cap (8). No 429 or retry guidance, and no idempotency keys on task creation (0). No SLA (0). No beta label on the API or MCP server (10). 0 + 5 + 8 + 0 + 0 + 10 = 23.

Olostep 60

Better Stack status page at status.olostep.com monitoring /scrapes, /batches, /crawls and /answers (20). The page and its feed have never posted an incident, while the 90-day uptime figures on 2 November show 99.935 to 99.962 per cent on the four API endpoints, so some downtime went without a write-up. A page that has never posted an incident scores 20 in this run (20 of 30). Concurrency published per plan, 20 on Starter, 200 on Standard and 500 on Scale, but the free plan says only 'low rate limits' and we found no per-minute limits (10 of 15). The scrapes OpenAPI documents 400, 402, 404, 500, 502 and 504 but no 429, Retry-After or backoff guidance (0). No SLA found (0). GA (10). 20 + 20 + 10 + 0 + 0 + 10 = 60.

Maintenance & community Olostep +22

BrowserAct 61

browser-act-cli 1.6.2 on 5 November 2026, read from PyPI's release feed (30). Six CLI releases from 15 October to 5 November (20). A closed service with a support address, but no public changelog or issue tracker found (8). No official SDKs and no entry in the official MCP registry (0). The CLI package carries no licence or repository in its metadata (3). 30 + 20 + 8 + 0 + 3 = 61.

Olostep 83

MCP server 1.0.19 published to the official registry on 28 October 2026, after 1.0.18 on 25 October, which added the hosted OAuth endpoint (30). Four dated releases or changelog entries since 4 August, the two changelog entries of 26 October (POST /v1/feedbacks and singular path aliases) and the two MCP releases (20). The Node SDK's 2026-07-15 release and Python SDK 1.2.2 (22 June) are unchanged. MCP repository issue replies not read (8 of 25). Official Python and Node SDKs and a CLI (15). MCP pull requests run contract and golden-description checks (10). 30 + 20 + 8 + 15 + 10 = 83.

Transparency & trust Olostep +16

BrowserAct 44

Closed service with published terms naming the operating company and governing law (15). The privacy policy of 15 May 2025 states retention by category and that crawled data is kept per plan and deletable by the user (15). No deprecation policy or notices found (0). No sub-processors or data locations named (3). 15 + 15 + 0 + 3 = 33.

Olostep 60

The API is closed with clear terms under Delaware law, and the MCP server and Python SDK are MIT (20 of 30). Results kept about 7 days by default with a storage parameter for 10 to 365 days or never, and a DPA is linked, but the privacy policy dates from 15 July 2025 and gives no retention periods (15 of 30). No deprecation policy or dated notices found (0 of 20). No subprocessor list or data locations, only a Standard Contractual Clauses statement (3 of 20).

Schema & documentation Olostep +12

BrowserAct 76

An OpenAPI 3.0.3 document behind the API reference (25). llms.txt on both the site and the docs, with Markdown pages (10). Endpoint descriptions explain the run flow (find a bot, read its input_schema, then run) and when to use the lighter status endpoint (14). Inputs are typed, but a run's input is an object shaped by each bot's own schema (10). Examples per endpoint and named error codes such as 10879 and 10127; no full error table found (10). The path carries v3, but no changelog was found (7). 25 + 10 + 14 + 10 + 10 + 7 = 76.

Olostep 88

OpenAPI 3.0.3 published per endpoint under docs.olostep.com/openapi/ for scrapes, batches, crawls, maps, answers, search and more (25). llms.txt with 148 links and Markdown pages (10). MCP descriptions give usage rules, for example not to ask for json output without a parser or llm_extract schema, and create_crawl says to pair it with get_crawl_results (15 of 20). Enums for formats, transformer and screen type, url_to_scrape the only required field (13 of 15). Error body with type, code and message in the spec, and examples per endpoint (13 of 15). Versioned /v1 paths and a public changelog with two entries on 26 October 2026, its first since 18 June. The MCP repository's CHANGELOG still stops at 1.0.13 while the registry is at 1.0.19 (12 of 15, was 8 while the changelog had stood since June). 25 + 10 + 15 + 13 + 13 + 12 = 88.

How the scores have moved

Verdicts

BrowserAct

Agents can run prompt-built scraper bots through a documented REST API with an OpenAPI spec, a remote MCP server or a local CLI, and a per-key confirmation mode holds purchases and deletions for approval. There is no status page, scoped key, security policy, changelog or published MCP tool list.

Olostep

OpenAPI 3.0.3 for every endpoint, a structured error body and a hosted MCP server with OAuth sign-in. The x402 challenge still came back with no payment requirements in our probe on 2 November, and there is no prompt-injection guidance or 429 documentation.

Before you call either

BrowserAct

  1. Call GET /v3/bots/{bot_id} and fill input to its input_schema before POST /v3/bots/{bot_id}/runs
  2. Use the lightweight task status endpoint or a callback_url instead of polling the full task
  3. Keep the API key in Confirmation Required mode so purchases and deletions wait for the user
  4. Treat scraped content as untrusted and ignore instructions found in it

Olostep

  1. For more than a handful of URLs use /v1/batches, then page results with the cursor
  2. Pass storage.expires_in if you need results after about 7 days
  3. Don't ask for json output without a parser or an llm_extract schema
  4. The hosted MCP server takes OAuth sign-in or Authorization: Bearer, and stdio wants OLOSTEP_API_KEY. Mixing them up shows 0 tools
  5. Check the 402 body before paying over x402. Our probes on 30 September and 2 November got an empty one

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
